The Packard Six was a series of luxury automobiles built over several generations by Packard from 1913 until 1947. The name was originally used to describe the car in general terms, while Series numbers were initially used and changed every year to denote wheelbases, then the number classification changed as market conditions changed so as to keep competitive with other luxury brands.

77-412: There are three generations that used a six-cylinder engine before World War II, with varying engine displacements and periodic mechanical changes. The Packard Six was the first top level luxury platform built by the company to introduce a six-cylinder engine, and was offered in three wheelbase options of 121.5 in (3,086.1 mm), 133 in (3,378.2 mm), and 139 in (3,530.6 mm). This

154-456: A condition called "stale fuel". Gasoline containing ethanol is especially subject to absorbing atmospheric moisture, then forming gums, solids, or two phases (a hydrocarbon phase floating on top of a water-alcohol phase). The presence of these degradation products in the fuel tank or fuel lines plus a carburetor or fuel injection components makes it harder to start the engine or causes reduced engine performance On resumption of regular engine use,

231-449: A controlled process called deflagration . However, the unburned mixture may autoignite by pressure and heat alone, rather than igniting from the spark plug at exactly the right time, causing a rapid pressure rise that can damage the engine. This is often referred to as engine knocking or end-gas knock. Knocking can be reduced by increasing the gasoline's resistance to autoignition , which is expressed by its octane rating. Octane rating

308-443: A fine mist. Quality gasoline should be stable for six months if stored properly, but can degrade over time. Gasoline stored for a year will most likely be able to be burned in an internal combustion engine without too much trouble. However, the effects of long-term storage will become more noticeable with each passing month until a time comes when the gasoline should be diluted with ever-increasing amounts of freshly made fuel so that

385-500: A gasoline depends upon: The various refinery streams blended to make gasoline have different characteristics. Some important streams include the following: The terms above are the jargon used in the oil industry, and the terminology varies. Currently, many countries set limits on gasoline aromatics in general, benzene in particular, and olefin (alkene) content. Such regulations have led to an increasing preference for alkane isomers, such as isomerate or alkylate, as their octane rating

462-466: A greater volume fraction of aromatics. Finished marketable gasoline is traded (in Europe) with a standard reference of 0.755 kilograms per liter (6.30 lb/U.S. gal), (7,5668 lb/ imp gal) its price is escalated or de-escalated according to its actual density. Because of its low density, gasoline floats on water, and therefore water cannot generally be used to extinguish a gasoline fire unless applied in

539-412: A growing annual target of total gallons blended. Although the mandate does not require a specific percentage of ethanol, annual increases in the target combined with declining gasoline consumption have caused the typical ethanol content in gasoline to approach 10 percent. Most fuel pumps display a sticker that states that the fuel may contain up to 10 percent ethanol, an intentional disparity that reflects

616-742: A heavier design than on previous years' models, while a column shift became and option alongside the center mounted shifter. This shape remained in use for 1939's 17th Series, the last of the Packard Twelves. 5262 examples were built in total, with the top sedan as the All Weather Cabriolet by Brunn & Company for US$ 8,510 ($ 184,202 in 2023 dollars ). For 1940 Packard's top model was the Packard Custom Super Eight . In October 1935, American President Franklin D. Roosevelt gave Joseph Stalin an armoured Packard Twelve, which became

693-574: A high compression ratio. A high expansion ratio is also one of the two key reasons for the efficiency of diesel engines , along with the elimination of pumping losses due to throttling of the intake airflow. The lower energy content of LPG by liquid volume in comparison to gasoline is due mainly to its lower density. This lower density is a property of the lower molecular weight of propane (LPG's chief component) compared to gasoline's blend of various hydrocarbon compounds with heavier molecular weights than propane. Conversely, LPG's energy content by weight

770-401: A higher compression ratio through the concomitant higher expansion ratio on the power stroke, which is by far the greater effect. The higher expansion ratio extracts more work from the high-pressure gas created by the combustion process. An Atkinson cycle engine uses the timing of the valve events to produce the benefits of a high expansion ratio without the disadvantages, chiefly detonation, of

847-628: A nation with a good supply of high-octane gasoline would have the advantage in air power. In 1943, the Rolls-Royce Merlin aero engine produced 980 kilowatts (1,320 hp) using 100 RON fuel from a modest 27 liters (1,600 cu in) displacement. By the time of Operation Overlord , both the RAF and USAAF were conducting some operations in Europe using 150 RON fuel (100/150 avgas ), obtained by adding 2.5 percent aniline to 100-octane avgas. By this time,

924-417: A representative species, performs the chemical reaction: By weight, combustion of gasoline releases about 46.7 megajoules per kilogram (13.0  kWh /kg; 21.2 MJ/ lb ) or by volume 33.6 megajoules per liter (9.3 kWh/L; 127 MJ/U.S. gal; 121,000 BTU/U.S. gal), quoting the lower heating value . Gasoline blends differ, and therefore actual energy content varies according to

1001-538: A sign of changing times, the majority of second generation Packard Twelves received standard bodywork, with custom bodywork gradually losing favor. Many of the custom cars were actually only "semi-customs", with Dietrich assembling Packard-made bodies with special touches. Packard introduced the Twin Six to stay competitive with Marmon , Pierce-Arrow , Rolls-Royce , Renault and other luxury brands. Cadillac and Lincoln began offering large luxury products starting in

1078-455: A smaller radiator than the all-new tenth series models. The Twin Six' V12-engine was retained without major change. The cylinder blocks are at a 67-degree angle, bore and stroke 3 + 7 ⁄ 16 and 4 in (87.3 and 101.6 mm) respectively. A 445.5 cu in (7,300 cc) displacement was the result and maximum power is 160 hp (119 kW) at 3200 rpm. The cooling system

1155-497: A twelve-cylinder engine, initially called the "Twin Six", then changing the name to "Packard Twelve," to align it with the rest of the Packard lineup. This was the 10th Series and two models were on offer: the 1005 and the 1006 had wheelbases of 142 in (3,606.80 mm) and 147 in (3,733.80 mm). The Twin Six' double drop frame was replaced by a tapered design. Convertibles and roadsters used leftover ninth series bodies with

1232-441: A typical gasoline consists of a homogeneous mixture of hydrocarbons with between 4 and 12 carbon atoms per molecule (commonly referred to as C4–C12). It is a mixture of paraffins ( alkanes ), olefins ( alkenes ), napthenes ( cycloalkanes ), and aromatics . The use of the term paraffin in place of the standard chemical nomenclature alkane is particular to the oil industry (which relies extensively on jargon). The composition of

1309-735: Is 10 percent ethanol, and 98E5, which is 5 percent ethanol. Most gasoline sold in Sweden has 5–15 percent ethanol added. Three different ethanol blends are sold in the Netherlands—E5, E10 and hE15. The last of these differs from standard ethanol–gasoline blends in that it consists of 15 percent hydrous ethanol (i.e., the ethanol–water azeotrope ) instead of the anhydrous ethanol traditionally used for blending with gasoline. The Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP) requires gasoline for automobile use to have 27.5 percent of ethanol added to its composition. Pure hydrated ethanol

1386-457: Is a naturally colorless liquid, many gasolines are dyed in various colors to indicate their composition and acceptable uses. In Australia, the lowest grade of gasoline (RON 91) was dyed a light shade of red/orange, but is now the same color as the medium grade (RON 95) and high octane (RON 98), which are dyed yellow. In the U.S., aviation gasoline ( avgas ) is dyed to identify its octane rating and to distinguish it from kerosene-based jet fuel, which

1463-504: Is also available as a fuel. Legislation requires retailers to label fuels containing ethanol on the dispenser, and limits ethanol use to 10 percent of gasoline in Australia. Such gasoline is commonly called E10 by major brands, and it is cheaper than regular unleaded gasoline. The federal Renewable Fuel Standard (RFS) effectively requires refiners and blenders to blend renewable biofuels (mostly ethanol) with gasoline, sufficient to meet

1540-456: Is called E85 . The most extensive use of ethanol takes place in Brazil , where the ethanol is derived from sugarcane . In 2004, over 13 billion liters (3.4 × 10 ^  U.S. gal) of ethanol was produced in the U.S. for fuel use, mostly from corn and sold as E10. E85 is slowly becoming available in much of the U.S., though many of the relatively few stations vending E85 are not open to

1617-490: Is higher than gasoline's due to a higher hydrogen -to- carbon ratio. Molecular weights of the species in the representative octane combustion are 114, 32, 44, and 18 for C 8 H 18 , O 2 , CO 2 , and H 2 O, respectively; therefore one kilogram (2.2 lb) of fuel reacts with 3.51 kilograms (7.7 lb) of oxygen to produce 3.09 kilograms (6.8 lb) of carbon dioxide and 1.42 kilograms (3.1 lb) of water. Spark-ignition engines are designed to burn gasoline in

1694-627: Is higher than n-alkanes. In the European Union, the benzene limit is set at one percent by volume for all grades of automotive gasoline. This is usually achieved by avoiding feeding C6, in particular cyclohexane , to the reformer unit, where it would be converted to benzene. Therefore, only (desulfurized) heavy virgin naphtha (HVN) is fed to the reformer unit Gasoline can also contain other organic compounds , such as organic ethers (deliberately added), plus small levels of contaminants, in particular organosulfur compounds (which are usually removed at

1771-422: Is left colorless. In Canada, the gasoline for marine and farm use is dyed red and is not subject to fuel excise tax in most provinces. Oxygenate blending adds oxygen -bearing compounds such as MTBE , ETBE , TAME , TAEE , ethanol , and biobutanol . The presence of these oxygenates reduces the amount of carbon monoxide and unburned fuel in the exhaust. In many areas throughout the U.S., oxygenate blending

1848-492: Is mandated by EPA regulations to reduce smog and other airborne pollutants. For example, in Southern California fuel must contain two percent oxygen by weight, resulting in a mixture of 5.6 percent ethanol in gasoline. The resulting fuel is often known as reformulated gasoline (RFG) or oxygenated gasoline, or, in the case of California, California reformulated gasoline (CARBOB). The federal requirement that RFG contain oxygen

1925-448: Is measured relative to a mixture of 2,2,4-trimethylpentane (an isomer of octane ) and n- heptane . There are different conventions for expressing octane ratings, so the same physical fuel may have several different octane ratings based on the measure used. One of the best known is the research octane number (RON). The octane rating of typical commercially available gasoline varies by country. In Finland , Sweden , and Norway , 95 RON

2002-406: Is produced in oil refineries . Roughly 72 liters (19 U.S. gal) of gasoline is derived from a 160-liter (42 U.S. gal) barrel of crude oil . Material separated from crude oil via distillation , called virgin or straight-run gasoline, does not meet specifications for modern engines (particularly the octane rating ; see below), but can be pooled to the gasoline blend. The bulk of

2079-481: Is series (Six only, Twin Sixes and Eights had their own series designation), 2nd and 3rd digits refer to wheelbase. F.e.: 233 is 2nd series Six, (longer) 133" wheelbase. 326 is 3rd series Six, (shorter) 126" wheelbase. The line consisted of: The Six was discontinued after the 5th series, and there was no Packard six cylinder car until the 1937 115-C. As the complicated naming system was revised for 1929, 626 and 633 refer to

2156-458: Is sporadic or seasonal (little to no use for one or more seasons of the year). Users have been advised to keep gasoline containers more than half full and properly capped to reduce air exposure, to avoid storage at high temperatures, to run an engine for ten minutes to circulate the stabilizer through all components prior to storage, and to run the engine at intervals to purge stale fuel from the carburetor. Gasoline stability requirements are set by

2233-486: Is the standard for regular unleaded gasoline and 98 RON is also available as a more expensive option. In the United Kingdom, over 95 percent of gasoline sold has 95 RON and is marketed as Unleaded or Premium Unleaded. Super Unleaded, with 97/98 RON and branded high-performance fuels (e.g., Shell V-Power, BP Ultimate) with 99 RON make up the balance. Gasoline with 102 RON may rarely be available for racing purposes. In

2310-680: Is used in Canada and the U.S. to boost octane rating. Its use in the U.S. has been restricted by regulations, although it is currently allowed. Its use in the European Union is restricted by Article 8a of the Fuel Quality Directive following its testing under the Protocol for the evaluation of effects of metallic fuel-additives on the emissions performance of vehicles. Gummy, sticky resin deposits result from oxidative degradation of gasoline during long-term storage. These harmful deposits arise from

2387-470: The Oldsmobile L-Series and DeSoto sixes and the retail price for a 4-door sedan was US$ 895 ($ 18,969 in 2023 dollars ) while the station wagon was listed at US$ 1,295 ($ 27,447 in 2023 dollars ). When production resumed after the war in the fall of 1945, the model year 1946 resumed with pre-war designs, and all models with the larger 245.3 cu in (4,020 cc) L-head engine were now called

2464-727: The Packard Clipper , with designations of Clipper Six. The listed retail price of the Clipper Series 2100 4-door Touring Sedan Model 1682 was US$ 1730 ($ 27,031 in 2023 dollars ). Packard Twin Six The Packard Twelve was a range of V12-engined luxury automobiles built by the Packard Motor Car Company in Detroit , Michigan . The car was built from model year 1916 until 1923, then it returned 1933 until 1939. As

2541-449: The U.S. Clean Air Act banned the sale of leaded fuel for use in on-road vehicles in the U.S. The use of TEL also necessitated other additives, such as dibromoethane . European countries began replacing lead-containing additives by the end of the 1980s, and by the end of the 1990s, leaded gasoline was banned within the entire European Union with an exception for Avgas 100LL for general aviation . The UAE started to switch to unleaded in

2618-556: The fractional distillation of petroleum and later chemically enhanced with gasoline additives . It is a high-volume profitable product produced in crude oil refineries. The fuel-characteristics of a particular gasoline-blend, which will resist igniting too early are measured as the octane rating of the fuel blend. Gasoline blends with stable octane ratings are produced in several fuel-grades for various types of motors. A low octane rated fuel may cause engine knocking and reduced efficiency in reciprocating engines . Tetraethyl lead

2695-811: The L-head engine was once again the only engine offered with a 116" wheelbase. It was officially identified as the Packard Single Six until it was joined with the Packard Single Eight in 1924. Once the eight cylinder engine was introduced, the Six was repositioned as a mid-level luxury car competing with the Buick Master Six and later the Chrysler Six , with a retail price of a 1921 5-passenger sedan listed at US$ 4,940 ($ 84,386 in 2023 dollars ). This generation introduced updated vehicle identification: 1st digit

2772-469: The Rolls-Royce Merlin 66 was developing 1,500 kilowatts (2,000 hp) using this fuel. Gasoline, when used in high- compression internal combustion engines, tends to auto-ignite or "detonate" causing damaging engine knocking (also called "pinging" or "pinking"). To address this problem, tetraethyl lead (TEL) was widely adopted as an additive for gasoline in the 1920s. With a growing awareness of

2849-671: The U.S., octane ratings in unleaded fuels vary between 85 and 87 AKI (91–92 RON) for regular, 89–90 AKI (94–95 RON) for mid-grade (equivalent to European regular), up to 90–94 AKI (95–99 RON) for premium (European premium). As South Africa's largest city, Johannesburg , is located on the Highveld at 1,753 meters (5,751 ft) above sea level, the Automobile Association of South Africa recommends 95-octane gasoline at low altitude and 93-octane for use in Johannesburg because "The higher

2926-410: The addition of 5–100 ppm of antioxidants , such as phenylenediamines and other amines . Hydrocarbons with a bromine number of 10 or above can be protected with the combination of unhindered or partially hindered phenols and oil-soluble strong amine bases, such as hindered phenols. "Stale" gasoline can be detected by a colorimetric enzymatic test for organic peroxides produced by oxidation of

3003-457: The altitude the lower the air pressure, and the lower the need for a high octane fuel as there is no real performance gain". Octane rating became important as the military sought higher output for aircraft engines in the late 1920s and the 1940s. A higher octane rating allows a higher compression ratio or supercharger boost, and thus higher temperatures and pressures, which translate to higher power output. Some scientists even predicted that

3080-588: The announcement "the end of one toxic era". However, leaded gasoline continues to be used in aeronautic, auto racing, and off-road applications. The use of leaded additives is still permitted worldwide for the formulation of some grades of aviation gasoline such as 100LL , because the required octane rating is difficult to reach without the use of leaded additives. Different additives have replaced lead compounds. The most popular additives include aromatic hydrocarbons , ethers ( MTBE and ETBE ), and alcohols , most commonly ethanol . Lead replacement petrol (LRP)

3157-612: The buildup may or may not be eventually cleaned out by the flow of fresh gasoline. The addition of a fuel stabilizer to gasoline can extend the life of fuel that is not or cannot be stored properly, though removal of all fuel from a fuel system is the only real solution to the problem of long-term storage of an engine or a machine or vehicle. Typical fuel stabilizers are proprietary mixtures containing mineral spirits , isopropyl alcohol , 1,2,4-trimethylbenzene or other additives . Fuel stabilizers are commonly used for small engines, such as lawnmower and tractor engines, especially when their use

3234-493: The customers preferences. Ten different body styles were available on either wheelbase while coupe and runabout body styles were only offered on the 125" wheelbase. The engine was a 60 degree L-head displacing 424.1 cu in (6,950 cc) producing 88 hp (66 kW) at 2600 rpm. Detachable heads and larger radiators came in 1916, a center-mounted gear shifter and brake levers in 1917. The range consisted of three series, built from May 1915 until June 1923. It

3311-450: The dictator's favourite automotive vehicle for many years. Gasoline#1903 to 1914 Gasoline ( North American English ) or petrol ( Commonwealth English ) is a petrochemical product characterized as a transparent, yellowish, and flammable liquid normally used as a fuel for spark-ignited internal combustion engines . When formulated as a fuel for engines , gasoline is chemically composed of organic compounds derived from

3388-509: The early 2000s. Reduction in the average lead content of human blood may be a major cause for falling violent crime rates around the world including South Africa. A study found a correlation between leaded gasoline usage and violent crime (see Lead–crime hypothesis ). Other studies found no correlation. In August 2021, the UN Environment Programme announced that leaded petrol had been eradicated worldwide, with Algeria being

3465-418: The end of production for cars using leaded gasoline in member states. At this stage, a large percentage of cars from the 1980s and early 1990s which ran on leaded gasoline were still in use, along with cars that could run on unleaded fuel. However, the declining number of such cars on British roads saw many gasoline stations withdrawing LRP from sale by 2003. Methylcyclopentadienyl manganese tricarbonyl (MMT)

3542-419: The gas) that can withstand the vapor pressure of the gasoline without venting (to prevent the loss of the more volatile fractions) at a stable cool temperature (to reduce the excess pressure from liquid expansion and to reduce the rate of any decomposition reactions). When gasoline is not stored correctly, gums and solids may result, which can corrode system components and accumulate on wet surfaces, resulting in

3619-641: The gasoline. Gasolines are also treated with metal deactivators , which are compounds that sequester (deactivate) metal salts that otherwise accelerate the formation of gummy residues. The metal impurities might arise from the engine itself or as contaminants in the fuel. Gasoline, as delivered at the pump, also contains additives to reduce internal engine carbon buildups, improve combustion and allow easier starting in cold climates. High levels of detergent can be found in Top Tier Detergent Gasolines . The specification for Top Tier Detergent Gasolines

3696-400: The last country to deplete its reserves. UN Secretary-General António Guterres called the eradication of leaded petrol an "international success story". He also added: "Ending the use of leaded petrol will prevent more than one million premature deaths each year from heart disease, strokes and cancer, and it will protect children whose IQs are damaged by exposure to lead". Greenpeace called

3773-516: The last quarter of the 19th century. The fuel for these early engines was a relatively volatile hydrocarbon obtained from coal gas . With a boiling point near 85 °C (185 °F) ( n -octane boils at 125.62 °C (258.12 °F) ), it was well-suited for early carburetors (evaporators). The development of a "spray nozzle" carburetor enabled the use of less volatile fuels. Further improvements in engine efficiency were attempted at higher compression ratios , but early attempts were blocked by

3850-472: The late 1910s. Large displacement engines provided the horsepower and torque their clients wanted and due to the low quality of gasoline fuel at the time, and low compression ratios , 50 bhp was more than adequate. It is estimated that the rating equivalent of early gasoline available varied from 40 to 60 octane and that the "High-Test", sometimes referred to as "fighting grade", probably averaged 50 to 65 octane. The first company produced 12-cylinder engine

3927-644: The new 1929 Packard Standard Eight in a similar way. 5th series Eight was omitted. Packard reintroduced the six cylinder model as the Packard Fifteenth Series Six Model 115-C, a lower priced companion to the One-Twenty . The first model year was 1937-1942 where it used a 237 cu in (3,884 cc) L-head engine, and was called the Packard One-Ten beginning in 1940. It was introduced as an affordable middle-class family car competing with

4004-406: The older gasoline may be used up. If left undiluted, improper operation will occur and this may include engine damage from misfiring or the lack of proper action of the fuel within a fuel injection system and from an onboard computer attempting to compensate (if applicable to the vehicle). Gasoline should ideally be stored in an airtight container (to prevent oxidation or water vapor mixing in with

4081-455: The oxidation of alkenes and other minor components in gasoline (see drying oils ). Improvements in refinery techniques have generally reduced the susceptibility of gasolines to these problems. Previously, catalytically or thermally cracked gasolines were most susceptible to oxidation. The formation of gums is accelerated by copper salts, which can be neutralized by additives called metal deactivators . This degradation can be prevented through

4158-449: The phaseout of leaded motor fuels in the United Kingdom, Australia , South Africa , and some other countries. Consumer confusion led to a widespread mistaken preference for LRP rather than unleaded, and LRP was phased out 8 to 10 years after the introduction of unleaded. Leaded gasoline was withdrawn from sale in Britain after 31 December 1999, seven years after EEC regulations signaled

4235-573: The premature explosion of fuel, known as knocking . In 1891, the Shukhov cracking process became the world's first commercial method to break down heavier hydrocarbons in crude oil to increase the percentage of lighter products compared to simple distillation. Commercial gasoline as well as other liquid transportation fuels are complex mixtures of hydrocarbons. The performance specification also varies with season, requiring less volatile blends during summer, in order to minimize evaporative losses. Gasoline

4312-427: The refinery). On average, U.S. petroleum refineries produce about 19 to 20 gallons of gasoline, 11 to 13 gallons of distillate fuel diesel fuel and 3 to 4 gallons of jet fuel from each 42 gallon (152 liters) barrel of crude oil. The product ratio depends upon the processing in an oil refinery and the crude oil assay . The specific gravity of gasoline ranges from 0.71 to 0.77, with higher densities having

4389-445: The season and producer by up to 1.75 percent more or less than the average. On average, about 74 liters (20 U.S. gal) of gasoline are available from a barrel of crude oil (about 46 percent by volume), varying with the quality of the crude and the grade of the gasoline. The remainder is products ranging from tar to naphtha . A high-octane-rated fuel, such as liquefied petroleum gas (LPG), has an overall lower power output at

4466-688: The seriousness of the extent of environmental and health damage caused by lead compounds, however, and the incompatibility of lead with catalytic converters , governments began to mandate reductions in gasoline lead. In the U.S., the Environmental Protection Agency issued regulations to reduce the lead content of leaded gasoline over a series of annual phases, scheduled to begin in 1973 but delayed by court appeals until 1976. By 1995, leaded fuel accounted for only 0.6 percent of total gasoline sales and under 1,800 metric tons (2,000 short tons; 1,800 long tons) of lead per year. From 1 January 1996,

4543-455: The standard ASTM D4814. This standard describes the various characteristics and requirements of automotive fuels for use over a wide range of operating conditions in ground vehicles equipped with spark-ignition engines. A gasoline-fueled internal combustion engine obtains energy from the combustion of gasoline's various hydrocarbons with oxygen from the ambient air, yielding carbon dioxide and water as exhaust. The combustion of octane ,

4620-419: The two-seat Coupe Roadster to the five-seat Formal Sedan. Standard bodyworks for the long wheelbase Model 1006 were Sedan and Sedan Limousine (both either five- or seven-seaters), with a host of custom bodyworks also on offer. These were mainly by Dietrich and LeBaron . The Super Eight long wheelbase chassis was no longer available, restricting custom bodyworks to the new Twelve. In 1934 the 11th series model

4697-408: The typical 10:1 compression ratio of an engine design optimized for gasoline fuel. An engine tuned for LPG fuel via higher compression ratios (typically 12:1) improves the power output. This is because higher-octane fuels allow for a higher compression ratio without knocking, resulting in a higher cylinder temperature, which improves efficiency . Also, increased mechanical efficiency is created by

Closed body choices were painted similar without cream yellow painted wheels. Brightwork was nickel plated, and a Warner speedometer , with a Waltham clock , among other items, were standard equipment. Optionally, the choice of interior and exterior colors were endless to accommodate

4851-504: The varying actual percentage. In parts of the U.S., ethanol is sometimes added to gasoline without an indication that it is a component. In October 2007, the Government of India decided to make five percent ethanol blending (with gasoline) mandatory. Currently, 10 percent ethanol blended product (E10) is being sold in various parts of the country. Ethanol has been found in at least one study to damage catalytic converters. Though gasoline

4928-499: Was available with a shorter wheelbase from 1915 until May 1919. From 1915 to 1920, the Twin Six was the sole offering from Packard. Production was 30,941 automobiles. Prices started at US$ 3,050 ($ 85,400 in 2023 dollars ) to US$ 5,150 ($ 144,200 in 2023 dollars ) for the Imperial Limousine. The 1919 Third Series Twin Six 3-25 Runabout was used as the pace car for the 1919 Indianapolis 500 auto race. For 1933 Packard reintroduced

5005-625: Was developed by four automakers: GM , Honda , Toyota , and BMW . According to the bulletin, the minimal U.S. EPA requirement is not sufficient to keep engines clean. Typical detergents include alkylamines and alkyl phosphates at a level of 50–100 ppm. In the EU, 5 percent ethanol can be added within the common gasoline spec (EN 228). Discussions are ongoing to allow 10 percent blending of ethanol (available in Finnish, French and German gasoline stations). In Finland, most gasoline stations sell 95E10, which

5082-402: Was developed for vehicles designed to run on leaded fuels and incompatible with unleaded fuels. Rather than tetraethyllead, it contains other metals such as potassium compounds or methylcyclopentadienyl manganese tricarbonyl (MMT); these are purported to buffer soft exhaust valves and seats so that they do not suffer recession due to the use of unleaded fuel. LRP was marketed during and after

5159-411: Was done by Count Alexis de Sakhnoffsky in his stint as a consultant at Packard. Only four Sport Coupes were built. This was the last car to be "Custom Made by Packard." The Model codes were 1106 (short), 1107 (middle), and 1108 (long). 960 Packard Twelves were built in 1934. This was also the first year that a radio was a factory option. For the 12th Series of 1935, the engine gained aluminum heads and

5236-478: Was dropped on 6 May 2006 because the industry had developed VOC -controlled RFG that did not need additional oxygen. MTBE was phased out in the U.S. due to groundwater contamination and the resulting regulations and lawsuits. Ethanol and, to a lesser extent, ethanol-derived ETBE are common substitutes. A common ethanol-gasoline mix of 10 percent ethanol mixed with gasoline is called gasohol or E10, and an ethanol-gasoline mix of 85 percent ethanol mixed with gasoline

5313-506: Was improved and a new Bendix-Stromberg EE-3 carburetor with an automatic choke was introduced, increasing power somewhat. A single dry-plate clutch replaced the earlier twin-plate model, matched to a floor-shifted three-speed manual transmission and a new one-piece driveshaft. The existing mechanical brakes were also adopted for the Twelve. The shorter wheelbase (Model 1005) was available with at least ten different styles of bodywork, ranging from

5390-518: Was in 1916, called the Packard Twin Six (1-25, 1-35) signifying two different wheelbases of 125 in (3,200 mm) and 135 in (3,400 mm), and was for four years the only product sold until the Single Six returned in 1921. The standard paint scheme for open cars, touring sedans, phaetons, and runabouts was Packard blue with cream yellow striping on body and door panels, with black used on

5467-462: Was introduced, adding a shorter third version on the 135 in (3.43 m) chassis of the Super Eight . An "Aero Sport Coupe" bodied in-house and a LeBaron -bodied "Runabout Speedster" were available on this wheelbase; only around ten of these two types were made. The appearance of the dramatic, almond-shaped Aero Sport Coupe was guided by Packard stylist Ed Macauley although the actual design work

5544-524: Was largely unchanged from the 12th (there was no 13th Series). The only differences were a radiator angled by five more degrees, the oil temperature regulator was redesigned, and the shortest wheelbase model was discontinued. Model year 1937 brought hydraulic brakes for the 15th Series Twelve; these had already been available for two years on the Packard One Twenty . Suicide doors were changed to conventional, front-hinged ones. With 1300 built, 1937

5621-469: Was once widely used to increase the octane rating but are not used in modern automotive gasoline due to the health hazard . Aviation, off-road motor vehicles, and racing car motors still use leaded gasolines. Interest in gasoline-like fuels started with the invention of internal combustion engines suitable for use in transportation applications. The so-called Otto engines were developed in Germany during

5698-549: Was stroked by a quarter inch, bringing up the displacement to 473.3 cu in (7,756 cc). Power was 175 hp (130 kW) at 3200 rpm and a high compression version with 180 hp (134 kW) was also available. The gearbox was now fully synchronized and both the mechanical brakes and the clutch received vacuum assist . The new wheelbases on offer were 132 + 1 ⁄ 2  in (3.37 m), 139 + 1 ⁄ 4  in (3.54 m), and 144 + 1 ⁄ 4  in (3.66 m). The 14th Series of 1936

5775-568: Was the Twelve's most successful year, and Dietrich offered six custom coachwork options. 1938's 16th Series brought yet shorter wheelbases: 127 + 3 ⁄ 8  in (3.24 m), 134 + 3 ⁄ 8  in (3.41 m), and 139 + 3 ⁄ 8  in (3.54 m). The shortest Model 1606 used the Super Eight chassis but was not included in Packard's brochures and it is unsure if any were built. Only 566 16th Series Twelves were built, followed by 446 17th Series. The fenders were of

5852-651: Was the last Packard to use the term "model" in its designation. Officially, the car was first introduced as the Packard Six Series 1-48. The car was described with varying marketing terms such as the Packard Six, the Packard Dominant Six, the Packard 'Six-48', '1248', and the Packard '48'. The '48' designation was assigned to 525 cu in (8,603 cc) T-head engines , while the Series 1-38 or '38' designation

5929-507: Was used for 415 cu in (6,801 cc) L-head engines that used a different valve configuration. The transmission offered three forward gears and was installed at the rear axle. The Six was replaced in 1916 with the Packard Twin Six and was the only platform manufactured in two wheelbases. Retail price of an Imperial Landaulet 7-passenger sedan was US$ 6,550 ($ 199,242 in 2023 dollars ). The line consisted of: Beginning in 1921,
