Sammit’s YouTube channel recently built a Mazda Miata with a forged 1.6L engine and spent multiple days on the dyno at HP Logic with Jack … To better judge ethanol's strengths and weaknesses, we decided to buy a flex-fuel vehicle (FFV) and put E85 to the test. Bear2013. [21], The examples and perspective in this article, The examples and perspective in this section, US EPA/OAR/Office of Transportation & Air Quality/Advanced Technology Division and FEV Engine Technology; Inc. "Economical, High-Efficiency Engine Technologies for Alcohol Fuels", Journal of the Air & Waste Management Association, Vol. My personal recommendation is to choose gasoline, due to the more expensive repair costs when using E85 in many cars. According to the U.S. Department of Energy, there are 3300 E85 gas stations available to the public across 42 states. Gasoline – Which one should I choose? Browse up-to-the-minute automotive news and analysis, including expert reviews of the latest cars on the market, at Cars.com. ! It can only be used in fuel systems designed specifically for E85 blends. The American Jobs Creation Act of 2004 created the Volumetric Ethanol Excise Tax Credit (VEETC) to subsidize production costs. There are four primary types of pollutants scientists study. While the price per gallon may be cheaper than 93 octane gasoline, you will be buying more of it at the pump. July 4, 2016, 9:54pm #1. In Brazil, ethanol fuel is neat at the pumps, hence flexible-fuel vehicles (FFV) including trucks, tractors, motorbikes and mopeds run on E100. E85 is an ethanol mixture promoted as an alternative to gasoline. Identification Ethanol has 34 percent less energy than gasoline per gallon, which equates to about 2 to 3 miles per gallon for E10 (10 percent ethanol), according to the New York Times. However, E85 in certain engine operating conditions may increase emissions of acetaldehyde. By Danny@Prodigy | 2020-11-04T09:40:43-05:00 Nov 4, 2020 | 0 Comments. It can be used in flexible fuel vehicles (FFVs), which are available from domestic and foreign automakers. The percentage of ethanol depends on the geographical location and time of the year. One car that has higher power on ethanol is the Koenigsegg CCXR, which on ethanol is the fifth-most powerful production car, with 20% more hp on E85 than on gasoline. The 85% fraction is commonly sold at pumps worldwide (outside the US), and when specifically supplied or sold as E85 is always 85% ethanol (at pumps or in barrel). Increased support and government subsidies mean that E85 and other flex fuels are here to stay. Because of the lower heating value E85 has a cooler intake charge—which, coupled with its high stability level from its high octane rating—has also been used as a "power adder" in turbocharged performance vehicles. In the US such FFVs are designed to run on any mixture of gasoline or ethanol up to 85% ethanol, whereas in countries such as Brazil where the climate is typically warmer, FFV run on neat alcohol. 45, Issue 39, Learn how and when to remove this template message. The tests have shown very little consistency if any at all because there are too many variables involved. While E85 gas costs less than regular gasoline at the pump, the decrease in miles per gallon makes it more expensive when driving. Search for the most efficient hybrid, diesel, and alternative fuel vehicles. As of July 1, 2014, there were more than 3,300 fuel stations that offered E85 fuel. [13] The availability ended in 2011, due to a severe excise-duty hike which rendered it economically unviable. October 21, 2019 Reply . General Discussion. In some parts of the country, stations offer gas with 15% ethanol. Because of Brazil's relatively warmer climate, gas stations in that country can sell pure ethanol. While it has been around for quite some time, it is just now starting to take hold in the US. The octane being the resistance to pre-detinaton or spontaneous combustion. For example, E85 is less volatile than gasoline or low-volume ethanol blends, which results in fewer evaporative emissions. The octane rating of pure ethanol is 100, but when it’s blended with gasoline, it performs as if it’s 112. Ethanol advocates[who?] E85 gas (also known as flex fuel) is a high-level combination of ethanol and gasoline that consists of 51 percent to 83 percent ethanol blended with gasoline. As shown, the amount of CO 2 emitted from gasoline and E85 is nearly equal (0.2% difference) on a Btu basis. Research by the U.S. Energy Information Administration shows that pure ethanol has a lower heating value than gasoline, so it makes it harder to start a car's engine in areas with a cold climate. Vehicles that use ethanol produce fewer emissions compared to those that run on diesel or regular gasoline. Tailpipe emissions result from fuel combustion in a vehicle's engine. We specialize in high horsepower forced induction engines. 1. So I have been debating this for a while.. well since its Winter, and there's nothing else to really do. Stage 3 Let's take it back to 2008, our owner and founder, Wes, had just finished a 5.7 HEMI swap for a ... E85 Ethanol vs. 93 Octane Gasoline There are three general categories of ethanol-gasoline blends: E10, E15, and E85. All 2001-model standard vehicles and newer can run on E15 but can't handle the corrosiveness of higher ethanol percentages. However, E85 can further reduce emissions of certain pollutants as compared to conventional gasoline or lower-volume ethanol blends. Most gasoline sold in the U.S. contains some ethanol, which is added as an oxygenator that reduces emissions. This fuel, which is popular in the US and sold under the E10, E20, e15 and E85 branding, is made up of up to 10% ethyl alcohol, which degrades very quickly.

Like all consumer products, there are pros and cons to using E85. E85 is an alternative fuel supported by many automakers on a wide range of cars. Feb 7, 2013 #1. In 2016, the installation of new ethanol infrastructure began in 20 states, thanks to a $210 million grant from the U.S. Department of Agriculture. The fuel economy difference between using E85 and gasoline is given as a range since E85 includes blends containing 51% to 83% ethanol: The lower bound (15% mpg decrease) is based on the difference in the energy content of a 51% ethanol blend and that of gasoline, which is typically 10% ethanol. Car research starts at Edmunds! Simple calculations of the BTU values of the ethanol and the gasoline indicate the reduced heat values available to the internal combustion engine. [19][20] In another test, however, a fleet of Ford Tauruses averaged only about 6% fewer miles per gallon in ethanol-based vehicles when compared to traditional, gas-powered Tauruses. Gasoline gallon equivalent (GGE) or gasoline-equivalent gallon (GEG) is the amount of alternative fuel it takes to equal the energy content of one liquid gallon of gasoline.GGE allows consumers to compare the energy content of competing fuels against a commonly known fuel—gasoline. The pros include: Ethanol is an alcohol fuel derived from several different plant materials, including corn, sugar cane, or various grasses. Cars.com reports that flex-fuel vehicles are capable of running on both ethanol-gasoline blends and regular gasoline. A gallon of gasoline provides one-third more energy than a gallon of ethanol. Ethanol-free gasoline is an optimal choice for your handheld outdoor equipment. E85 vs. E10 is gasoline with 10% ethanol content. Brazil makes theirs from sugarcane. Dale Lattz and Gary Schnitkey • Weekly Farm Economics • Machinery cost estimates for agricultural uses have been updated for 2019. The burning of fuel produces energy. The main difference between Ethanol and Gasoline is that Ethanol is composed of only ethyl alcohol molecules whereas Gasoline is composed of several types of organic molecules. E85 is the most common form of flex fuel available on the market. Between 2017 and 2019, most per acre costs increased between 7 and 9 percent. Ethanol vs Gasoline. In the United States, the exact ratio of fuel ethanol to hydrocarbon may vary according to ASTM 5798 that specifies the allowable ethanol content in E85 as ranging from 51% to 83%. E85 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume. E85 (or flex fuel) is a term that refers to high-level ethanol-gasoline blends containing 51% to 83% ethanol, depending on geography and season (see Fuel Properties and E85 Flex Fuel Specification). E85 has a lower BTU than traditional gasoline. Handbook for Handling, Storing, and Dispensing E85 and Other Ethanol-Gasoline Blends. On the other hand, E85 or 85% ethanol gasoline requires approximately a 9.85:1 AFR to achieve stoichiometric. When drivers use E10 or E15 instead of pure gasoline, they will notice a decrease in miles per gallon. Although ethanol fuel is not perfect, researchers are working around the clock to beef up its efficiency to make it a reliable energy source by getting rid of its disadvantages. E85 advocates counter that concern by pointing out that over 93% of all corn grown in the United States is never fed directly to people, but is instead used as livestock feed[citation needed]. Since the advent of E85 in the early 2000s, people have been using it as go-fast juice due to its intrinsic knock resistance and cooling properties. Consumers can use the Department of Energy's vehicle cost calculator to determine how much a flex-fuel vehicle can save on fuel costs and greenhouse gas emissions. Pump Gas vs E85 tunes. It also reduces the chances for engine “knock” or “pinging.” Regular gasoline usually contains 10% ethanol. Sometimes, we make our choice depending on the price difference. The last time machinery costs were released on farmdoc was in 2017. It is a renewable resource that is produced domestically rather than imported. Ethanol Fuel is a Source of Hydrogen. There are many differences between E85 and gasoline. [16][17] E85 also has higher octane content, which can provide more engine power. Advertisement . This is because compared to pure gasoline, ethanol has about one-third less energy. In the United States, to realize equivalent fuel economy at the pump with an FFV, the price of E85 must be much lower than gasoline. E85 has less potential energy compared to gasoline, which is why mileage suffers with E85, but we’re using it for its other benefits. Tequila: E85 Fuel A mixture of 85-percent ethanol and 15-percent gasoline, E85 is considered by many to be a poor-man’s race fuel – and for good reasons. Here you will find the biggest things to consider before making your choice. In gas station when we see E10 (ethanol) and regular unleaded gas we ask why choose one over the other. ! Shell V-Power ® NiTRO+ Premium Gasoline is an innovative premium formulation engineered with four levels of defense against gunk, corrosion, wear and friction to help keep your engine running like new *. In addition to use as a gasoline additive, fuel ethanol forms the bulk of E85, also known as flex-fuel. This includes failed fuel injectors, fuel pumps, etc. David Freiburger and Steve Dulcich at Engine Masters wanted to find out which makes more power and by how much.So they grabbed a 489-cubic-inch, 13.5:1 compression big block Chevy, teamed up with our partners at Summit Racing for a couple of key parts, and started playing.. To ensure a level playing field, they used Rockett Brand’s 114-octane race gas … In one US test, an early model 2.75-ton Chevy Tahoe FFV averaged 18 MPG (U.S. gallons) for gasoline and 13 MPG for E85, 28% worse than gasoline. A federal mandate limits the amount of 100-percent gasoline on the market. Kyle Brixey’s Trailblazer SS is no stranger to boost. Critics of E85 and ethanol, in general, argue that its lower heating value outweighs any benefits. [12] E85 as a fuel is widely used in Sweden; however, most of it is imported from Italy and Brazil. E85. In countries like Australia where E85 is always 85% ethanol (and pump fuel with varying fractions is called "flex fuel"), performance motoring enthusiasts and motor racing clubs/championships use E85 extensively (without the need for any FFV certification). In an advanced engine, E85 can improve the engine's fuel consumption. So does that mean that the miles per gallon indicator ( either average or instantaneous) will show higher miles per gallon? 3. Gasoline or E85 ethanol-blended fuel? On the face of it ethanol actually has a slightly lower energy content than gasoline per kilogram, but it also has a much richer stoichiometric AFR (9.8:1 for E85 vs 14.7:1 for pump gas) which means we need to use more of it to mix with the same mass of air. Ethanol and gasoline are two types of fuel mostly used in vehicles. In Brazil, sugar cane is a prominent source of ethanol. I inquired about running E85 on my car, so really push this 16g. E85 is a fuel that is made of 85 % ethanol, and 15% gasoline. Depending on the driver's location and the ups and downs of the energy markets, the cost of E85 can vary greatly, especially when compared to regular gasoline and E10. There has been some debate with the usage of energy sources today, much more that everyone has become environment conscious with regard to the impact of energy on the planet. This difficulty in cold cranking is why ethanol blends contain a fraction of gasoline. My Nissan Juke do not exellerate. You will read estimates of 15- to 18-percent loss in mileage-per-gallon when using E85 compared to gasoline in flex-fuel vehicles (FFV). Some vehicles can be converted to use E85 despite not being specifically built for it.

AlternativeFuels*Data*Center*–*Fuel*PropertiesComparison*!www.afdc.energy.gov!! In contrast, ethanol critics contest the benefits of E85 by focusing on the fact that E85 has 33% lower heating value compared to the higher heating value of gasoline. A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline. E85, for instance, reduces fuel economy by 7 to 8 miles per gallon when compared to gasoline, according to the Environmental Protection Agency. The percentage of ethanol depends on the geographical location and time of the year. It's wrong, they say, to base ethanol engine design on that of a gas engine when ethanol is closer to diesel fuel. Plus, ethanol is a renewable energy source made from corn. We use a BSFC of .55 for forced induction. Get detailed expert vehicle reviews and ratings for every car on the market. Throttle: Drive-by-wire controlled port throttles The Society of Automotive Engineers and other supporters of E85 usage argue that if automotive manufacturers would recognize and take advantage of ethanol-based fuel's superior traits, they could make an ethanol engine that was as efficient as one powered by gasoline. GGE also compares gasoline to fuels sold as a gas (natural gas, propane, hydrogen) and electricity. On a Jet Plane, Illinois. There are both great advantages and great disadvantages associated with the use of ethanol as an alternative fuel to petroleum. Using this approach, the EPA has produced an ethanol-only engine which achieves much higher brake thermal efficiency levels than gasoline engines achieve. B) ENVIRONMENT: E85 burns cleaner than gasoline and emits less particulate matter into the air, far less than unleaded gasoline. Another advantage of the ethanol content in the E85 is that it doesn’t have the corrosive issues you may experience in methanol. Stainless steel fuel lines, sometimes lined with plastic, and stainless-steel fuel tanks in place of terne fuel tanks have been used. Despite the lower miles per gallon, flex-fuel vehicles often put out more torque and more horsepower when running on E85 instead of regular gasoline. [1] This is due to the lower heating value of neat ethanol making it difficult to crank engines in relatively cold climates without pre-heating air intake, faster cranking, or mixing varying fractions of gasoline according to climate. Corn used to produce ethanol contains a high amount of starch and is not easily digestible by humans, like sweet corn. E85 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume.. In the United States, government subsidies of ethanol in general and E85 in particular have encouraged a growing infrastructure for the retail sale of E85, especially in corn growing states in the Midwest. [3] For us, the E85 trip was about $30 more expensive — about 22.9 cents per mile on E85 versus 18.7 cents per mile with gasoline. But for our purposes, non-ethanol gasoline requires a 14.7:1 AFR to achieve stoichiometric, while E10, or 10% ethanol gasoline, requires a 14.0:1 AFR to achieve stoichiometric, which is an optimal air/fuel ratio. Blending ethanol and gasoline at a ratio of 85 percent to 15 percent (E85), the blended fuel is nearly thirty percent less powerful than pure gasoline. Hence, people are now thinking twice whether they’ll still use the same good old gasoline for their cars over the newly invented bio fuels and the like. To determine which is cleaner, gasoline or ethanol, researchers must “compare these fuels over their full life cycle.” Hill explains: That is, we need to consider the damage caused by producing them in addition to using them. Because it is highly oxygenated and requires increased fuel flow compared to conventional non-oxygenated fuels, consult with your fuel injection system or carburetor supplier for correct air/fuel ratio calibrations. Depending on the climate you are in, E85 typically contains a blend of 85% ethanol and 15% gasoline. Using a guaranteed fraction of ethanol makes it easier for a vehicle to reach peak performance and fuel economy. Ethanol Uses. You’ve probably heard about the benefits of using E85 for your performance vehicle and how you can make more power using it, but do you know why? E85 Ethanol vs. 93 Octane Gasoline. Main Difference – Ethanol vs Gasoline. What could be the problem. Advertisement. Because E85 is predominantly ethanol, the exhaust emissions are very different from those of regular gasoline. View Larger Image; We have been hearing about E85 ethanol, or flex fuel, for the better part of a decade now. Most gasoline available in the U.S. is blended with 10- to 15-percent ethanol … E85 vs. E85 (or flex fuel)—a high-level, gasoline-ethanol blend—is less volatile than gasoline and low-level ethanol blends and results in lower evaporative emissions. E85 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume.. Numerous studies have compared and contrasted the different emissions and the effects these emissions have on the environment, but the tests have been inconclusive. It's less available in other regions, especially New England and the Pacific Northwest. Other measures taken by Congress to jump start ethanol production include the 2004 VEETC bill, which provided for a Small Ethanol Producer Tax Credit which gave tax credits to small ethanol producers. Thanks to the lack of alcohol in it, this type of gas will not tend to attract particles of water and moisture into the fuel tank, line, or storage container. The most common use of manufactured ethanol is as a vehicle fuel for internal-combustion engines. Key Areas Covered. E85 gas (also known as flex fuel) is a high-level combination of ethanol and gasoline that consists of 51 percent to 83 percent ethanol blended with gasoline. According to the manufacturer, this is due to the cooling properties of ethanol. According to these proponents, an ethanol engine that can reach up to 22 percent more miles per gallon than a gasoline engine already exists. We may earn a commission for purchases made through our links. What is E85 vs E90 vs E70? E85 has about 33% less BTUs than traditional gasoline. As an example, a gallon of gasoline typically will produce 114,000 BTUs of heat while ethanol comes in at a lower rating of 76,600 BTUs per gallon. There are a few major differences between FFVs and non-FFVs. Table 1 compares gasoline and E85 on the basis of CO 2 emitted per million Btu. Because ethanol is corn-based, E85 gas is readily available in the Midwest region of the United States. [clarification needed] Since its 85% ethanol Vs 10% ethanol (Gas) And proportionally the octane in gas is 91-93 Vs E85 being 100. !!!!!10/29/2014! In Finland E85 is available from 52 St1 chain locations and 71 ABC chain locations. E85 is an alternative fuel supported by many automakers on a wide range of cars. E85–Gasoline WTW Energy and Emissions Comparison CO 2 is a major GHG and the predominant emission produced during combustion of carbon-containing fuels. 95talongirl Supporting Member. E85 has less potential energy compared to gasoline, which is why mileage suffers with E85, but we’re using it for its other benefits. These modifications have not only resulted in lower GHG emissions, but typically resulted in 10-12% power and torque increase at the wheels. Having a guaranteed ethanol fraction obviates the need for a vehicle system to calculate best engine tune according to maximise performance and economy. It can’t pass 40 kmh. But an interesting change occurs with E85. A BTU is a British thermal unit, which basically is how much energy is in the fuel itself. One disadvantage of ethanol fuel is that it has been reported to cause engine burns and corrosion. It delivers unsurpassed protection against gunk, unbeatable protection against corrosion, and our best protection against wear and friction. I should also note that ethanol can be made from ANY plant matter. As more effort is put into maximizing an engine to take advantage of E85's higher "octane", engines achieve greater power advantages. E85 vs. Race gas Posted by 95talongirl, Feb 7, 2013. E85 was originally introduced to the mainstream market around the … Fuel is a source of energy. Sunoco E85-R is an unleaded racing fuel containing 85 volume % ethanol. Pure ethanol provides 2/3 of the heat value available in pure gasoline. [citation needed], E85 promoters and the Society of Automotive Engineers contend that automotive manufacturers currently fail to equal the fuel consumption of gasoline because they fail to take advantages of characteristics which are superior in ethanol-based fuel blends. The Renewable Fuels Association defines a flex fuel as a blend of ethanol and gasoline that contains more than 15 percent ethanol and less than 83 percent ethanol. [14][15] The E85 sold by St1 is labeled as RE85 and as "Eko E85" in ABC-stations to indicate it is manufactured from Finnish bio-waste. Others say that the world can easily replace all of its use of petroleum by simply making ethanol from the many crops that yield more ethanol per acre than corn yields, with existing technology, not future technology,[11] and that certain elements in the cellulosic ethanol field are more interested in patent rights than in producing the greatest amount of ethanol at the lowest price point. Gasoline vs E85 Comparison. Supporters counter that argument by pointing out that heating value does not factor into overall efficiency. E15 is gasoline with 15% ethanol content, and E85 is a fuel that may contain up to 85% fuel ethanol. E85 was formerly available from the Maxol chain in Ireland, where it was made from whey, a byproduct of cheese manufacturing. !!!!!1! Well, you realistically have two choices if you don’t want to run race gas: E85 or water/meth injection. Supporters, such as the Renewable Fuels Association, say E85 ethanol fuel expands the market for U.S. crops and creates jobs in agriculture and refining. Mileage is dependent upon the composition of the ethanol-gasoline blend, transmission, state of engine tune (primarily fuel-air mixture, spark timing and compression ratio). In the United States to offset this difference in fuel consumption in vehicles not optimised for ethanol, legislation has been passed to subsidize its cost. Stanford University’s Mark Jacobson estimates that E85 fuel in “flex-fuel” vehicles may increase ozone-related mortality, asthma, and hospitalizations by 4 percent compared to gasoline by 2020 for the U.S. as a whole and 9 percent in Los Angeles alone. 40 % in lower GHG emissions, but ethanol in petrol is here to stay alternativefuels * *!
