Ethanol Fuel. E85 has an average energy content of 81,800 BTU/gallon. much more clear! Politicians have been made aware that since the British public have changed back to buying petrol (gasolene) powered cars from diesel, the CO2 emmisions from road transport have gone up. A car running on E85 has about 80% the efficiency of the same car running on gasoline. Unfortunately, there were only 1,208 E85 filling stations -- less than 1 percent of the total filling stations in America. Until you burn through the E85, we recommend that you top off your fuel regularly to dilute the E85 as soon as possible. Unless you know what you're doing and the pros and cons of burning this in your vehicle." I compared how clean the three fuels burn. Thoughts? A car running on E85 has about 80% the efficiency of the same car running on gasoline. E85 is an ethanol mixture promoted as an alternative to gasoline. Hunderd's of thousands of people have converted thier vehicles to burn E85 with no problems. But assuming your car is already burning proper fuel mixture, it should be almost no difference. I'm in the middle of building a 600hp LC2, Buick 3.8L v6, motor for my Grand National. Q: I know that pure alcohol burns almost invisible in daylight. While ethanol does burn cleaner than gas, meaning less smog, flex fuel cars still produce roughly the same amount of greenhouse gases as their fossil fuel counterparts. Some penny pinchers have even installed legal moonshine stills in their own backyards, to save on gas money. Ethanol fuel is ethyl alcohol, the same type of alcohol found in alcoholic beverages, used as fuel.It is most often used as a motor fuel, mainly as a biofuel additive for gasoline.The first production car running entirely on ethanol was the Fiat 147, introduced in 1978 in Brazil by Fiat.Ethanol is commonly made from biomass such as corn or sugarcane. A blend that holds ~85% ethanol and ~15% gasoline. If you are referring to E85 its because ethanol contains less energy they gas. E85 is around 105 octane. Gasohol burns cleaner, but you pay for it with lower fuel economy. There are several E85 stations in my area. It does burn cleaner than gasoline. Tyler on April 03, 2017: Ethanol is a cleaner burning fuel and it is better for the enviroment. Does e85 burn cleaner? E10 can be used in any new car. I use gasoline as little as I can but E85 really needs to come down in price to be more competitive. These evaporative emissions contribute to the formation of harmful, ground-level ozone and smog. Check out my new burn test! My vehicles usually burn E85 OBD1 vehicles (2 years). Second on this list is water or coolant, obviously everyone knows that water will not burn and should never be in your fuel tank. JDnHuntsvilleAL on March 01, 2017: E85 fuel Conventional gasoline blended with 85 percent ethanol is a different story. I was considering E85, since its 85% ethanol I thought that maybe it would burn cleaner. Adding ethanol to gasoline makes it cleaner and reduces air pollution, right? Now, I don't travel 80mph nor have a turbo. 1. Ethanol on its own has a much higher octane rating than normal gas. They are timed for it. Having posted this, I am aware of no actual internal engine damage burning E85. This means that if you choose to use higher blends of ethanol gasoline, the performance of your car may improve dramatically in the areas of horsepower and torque. All major U.S. automakers offer cars, vans, and light trucks designed for E85, often at the same prices as their gaso-line counterparts. Gasoline cars produce more carbonaceous particulate matter than modern filter-equipped diesel cars, Scientific Reports Specifically, burning E85 resulted in fewer ozone-forming compounds than gasoline. So RON95 un-leaded fuel contains upto 5% ethanol. More information: S. M. Platt et al. Not as efficient. I'm going to be running E85, one for the inherit higher octane rating and two it does appear to keep your engine, pistons and heads, cleaner and three it is cheaper and doesn't contain lead like C16. It doesnt by itself. E85 meet these challenges with special lubricants and selected components made from advanced materials. In 2007, there were 5.5 million Flex Fuel Vehicles on the road in the U.S. that could run on E85 fuel. Unleaded 88 is the most tested fuel in history, and is EPA-approved for use in all 2001 and newer cars, SUVs, and light-duty trucks. I agree. Using Unleaded 88/E15. This may be what you are referring to. And as far as pollution, the gasoline industry makes the most cancer causing chemicals of any industry in the world. But E85 does burn cleaner. Technology for ethanol production is cleaner than in the past and those issues will be worked out. Others drive on the more controversial E85, which is 85 percent alcohol. There are some tweaks to oxygen sensors and a couple other things to get it really working well that may impact some of the readiness monitors. Vehicles running on E85 tend to experience a drop in fuel economy versus gasoline (up to 25-30%) due to Ethanol's lower energy content but at the benefit of burning cleaner. The start/priming technique is the secret. While ethanol does burn cleaner than gas, meaning less smog, flex fuel cars still produce roughly the same amount of greenhouse gases as their fossil fuel counterparts. It goes from 21 MPG average to 19 MPG average. Ethanol and ethanol-gasoline mixtures burn cleaner and have higher octane levels than pure gasoline, but they also have higher evaporative emissions from fuel tanks and dispensing equipment. Which would a loss of about 3 mpg in this example. If your price spread is about 20% (most places aren't right now), then your cost-per-mile will be equal or better using e85. But, as long as you dont consistently put E85 into your gas tank, you should be Your best protection, take it easy and don't demand high hp of your engine. I just use 87 for most fill ups. So biofuel lobbyists would have us believe. My fuel economy does drop with E85. E85 is 85% ethanol and E15 is 15% ethanol. I was reading something the other day about someone doing an E85 conversion on some car and they said that not only does it burn cleaner but the E85 fuel has a higher octane than normal gasoline. A vehicle using E85 would require 1.39 gallons to go the same distance as one gallon of conventional gasoline. A8, catch can, headlight to airbox tube, Abs cover, Scat Pack puddle lights, Scat Pack rear panel vinyl, JLT Coolant Tank cover. Now in the long run, E85 does burn cleaner, is 104 octane, and American made. I get E85 whenever it is convenient and cheaper than regular gas though. Not very green in my humble opinion. My MPG went up, but the truck seemed sluggish. I use e85 almost exclusively, since it's American made, burns cleaner and is our country's best gasoline replacement. Otherwise, people wouldn't covert. "E85 Don't Do It! Yes, it does burn cleaner in the chamber. Straight ethanol, the alcohol used in E85, burns with a pale yellow flame. Car Bibles states that more people today are concerned about fuel consumption's effects on the environment. But with the introduction of ethanol fuel, which can legally be from 10% to 85% many fuel tanks end up with gallons of water just due to ethanol separation. Ethanol in E10 serves as an oxygenate, which helps gasoline burn cleaner to reduce smog. It only does in an engine designed for that slower burn (slower, not faster). For example if your car gets 8 mpg on E10 then using E85 would get you 0 mpg according to this article. The less time you have your engine running with the wrong ethanol mixture, the better. Welcome! E85 is a fuel blend. I find this hard to believe but I wanted to pose the question and see if there are any fuel experts who can back this up. The resulting fuel is called E85, denoting 85 percent ethanol and 15 percent gas. Ethanol is added to normal pump gas to help the engines burn cleaner but is only at about a 10-15% ethanol to gas ratio. These are flexible-fuel vehicles that can run on E85, gasoline, or any combination of the two. As for E85, it does burn much cleaner than gasoline so if where you are does a tail pipe test it should be no problem, but if they do an OBDII test it will depend on how the tune is setup I believe. You'll probably see about a 15-20% drop in MPG since e85 has less energy than gas. While ethanol does burn cleaner than gas, meaning less smog, flex fuel cars still produce roughly the same amount of greenhouse gases as their fossil fuel counterparts. In reality you would actually get 2/3 the mpg of E10 using E85. A: Pure methanol (wood alcohol) burns with a pale blue light that is nearly invisible in daylight. I've been running e85 exclusively for the last two years, but had to fill up twice last week with gasoline. At one time the cost trade off made it worth it to use E85, but not anymore. E85 has an average energy content of 81,800 BTU/gallon. Since it has less energy means you need more of it to do the same thing. Does E85 also burn invisibly? As I had stated earlier in this article ethanol is a great cleaner and this alone can cause issues as it dislodges built up dirt sending harmful and filter clogging particles through your fuel system and engine. A car running on E85 has about 80% the efficiency of the same car running on gasoline. "[E85] compared very favorably to a low-sulfur, low-benzene, oxygenated gasoline." Cleaner for the Environment. E85 does have a higher octane rating but it has less energy so the result is less mpg and less hp unless the timing is adjusted to take advantage of the higher octane. This will burn out fuel pumps. E85 fuel, on the other hand, is about 85% ethanol to 15% gas. Related: What's the difference between white gas, propane, kerosene, and gasoline? Similarly, it is asked, does e85 burn cleaner? edit/update: I have had good luck with standard premium gas. I would like a post or section of E85 to list actual engine damage of E85 fuel. Most planes with MOGAS STCs were originally certified for less octane than 100LL, so they are designed to run with a faster burn that lower octane provides. Your engine is made to run on 0% ethanol but has been adapted to run on ethanol which is lower octane so you have to burn more of it to get the same amount of energy so even though E85 is cheaper you will negate the savings because your miles per gallon goes way down. Fuels blended with ethanol burn cleaner and cooler, helping your engine to run more efficiently. What is E85? Unleaded 88/E15 is a fuel blend containing 15% ethanol and 85% gasoline that burns cleaner than regular gasoline. However, a study published in Proceedings of the National Academy of Sciences (PNAS) comes to the opposite conclusion.. Lead author Jason Hill of the University of Minnesota Department of Bioproducts and Biosystem Engineering summarized key findings of the
