Should I be using one over the other? Have I been putting the wrong type of fuel in my vehicle? Often times the choice is based on price, availability, and the manufacturer's recommendations.
If ethanol is less efficient than gasoline and can even damage cars, why is it being blended and sold? First, gasoline blended with ethanol burns cleaner than pure gasoline. The second reason is that ethanol comes from corn, and it is big business. Agribusiness is a powerful lobby in Washington and with environmentalists siding with them on this issue; the use of ethanol will spread. While E10 is widely available, E15 gasoline is only sold in a handful of states and then in just a few filling stations.
E15 is sold in Kansas, Iowa, and Nebraska. When the Environmental Protection Agency approved E15, it restricted its use and excluded the following from running on it. All major vehicle manufacturers are exploring voiding warranties on cars using E15 despite engineered for no more than E10 fuel.
Do not put diesel or regular leaded gasoline inside an FFV. Admittedly, leaded gasoline is very rare these days, but if you happen to come across some, keep it out of your FFV tank. The flex-fuel designation generally means you can put E85 gasoline or regular unleaded gas in your vehicle. Ever Wonder: Why is there a lot of oil in the Middle East?
The reason for this is that ethanol burns faster than regular gas. Drivers should notice no performance loss when using E In fact, some FFVs perform better —have more torque and horsepower—running on E85 than on regular gasoline. So while you can mix E85 with regular gasoline it's not really beneficial in any way even if you have a flex fuel vehicle because they don't really gain hp by utilizing E85 or any blend in between and they actually get less fuel range the higher the ethanol ratio.
Will e85 damage my engine? Ethanol has a corrosive action on fuel-system components, magnesium, aluminium and rubber. Running E85 on an older model engine without tuning it and replacing some components will ruin the engine in short time. Replacing fuel hoses, fuel pumps, gaskets, seals, fuel filters, fuel injectors, throttle bodies, etc. Does e85 give you more power? E85 fuel can give you a significant boost in power and torque without breaking the bank for racing fuels.
It has a base octane rating of and has the bonus of added cooling properties that add even more knock resistance than racing fuels with the same rating. What is the benefit of e85 fuel? E85 can be perfect for the high horsepower or high compression build, as long as it is readily available in your area.
Because of E85s increased resistance to detonation, it allows for more power without the cost of expensive race fuels. Department of Energy, there are E85 gas stations available to the public across 42 states.
Outside the United States, ethanol producers often use alternative crops. In Brazil, sugar cane is a prominent source of ethanol. Research by the U. 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. This difficulty in cold cranking is why ethanol blends contain a fraction of gasoline. E85 gas is suitable for use in any vehicle designated as a flex-fuel vehicle by the manufacturer.
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.
Because of Brazil's relatively warmer climate, gas stations in that country can sell pure ethanol. Flex-fuel vehicles in Brazil run on E as opposed to the E85 that is for sale in most parts of the world. Fuel sold as E is always percent ethanol, while fuel sold as E85 always contains 85 percent ethanol. Using a guaranteed fraction of ethanol makes it easier for a vehicle to reach peak performance and fuel economy.
In Austalia, E85 is the preferred fuel among motor racing clubs and sports car enthusiasts. The motor racing industry has always preferred ethanol- or methanol-based fuels because these fuels tend to give performance vehicles more thermal efficiency and increased torque.
In an advanced engine, E85 can improve the engine's fuel consumption. In the United States, the government has tried to encourage the production and sale of E85 by providing subsidies, particularly to corn producers in the Midwest.
