Is 15 percent ethanol bad for your car?

One of the major complaints by E15 opponents is that ethanol can corrode many of the plastics, metals, and rubber components used in internal-combustion engines and their fuel systems. Hence, using fuel with a higher concentration of ethanol than the manufacturer recommends may damage your vehicle.

Will E15 hurt my engine?

Bob Dinneen, CEO of the Renewable Fuels Association, says E15 is safe for virtually all post-2001 vehicles, based on extensive government-sponsored testing. “We think the (EPA) warning label should be sufficient to notify consumers,” Dinneen says. “There are no corrosive issues with E15.

What happens if I put 15 ethanol gas in my car?

Running E15 gasoline in a car that is not approved for it could cause engine problems. Independent research by AAA’s auto engineers also finds that using E15 in new and older cars could cause damage to the fuel system, speed up engine wear and cause the “check engine” light to illuminate.

Can I use E15 in my e85 car?

They can run on anything from 100-percent gasoline to blends containing 85 percent ethanol. All 2001-model standard vehicles and newer can run on E15 but can’t handle the corrosiveness of higher ethanol percentages.

Is 10% ethanol bad for cars?

The short answer is, no, ethanol-free gasoline is not bad for your car. Most cars today can run on ethanol gas blends up to E15 (15% ethanol) and on non-ethanol gasoline. And flex fuel vehicles can handle up to E85 (85% ethanol) without a problem.

Why is E15 bad?

E15 is shorthand for gasoline blended with 15 percent ethanol. The reason it’s a big deal is that ethanol is fairly corrosive to rubber and certain metals, so it can cause damage to vital components.

Can I use 87 instead of E15?

So an engine designed for E15 can run regular gas with up to 15% ethanol (aka alcohol) or less (E10 or E5) or regular gas 87 octane (no ethanol), or mid-range 89 octane, or premium 91+ octane.

Will E85 hurt my engine?

E85 is actually safer for your engine than regular gasoline is. E85 flex fuel not only powers your engine but also cleans your engine, fuel lines, and fuel injectors. That’s because E85 contains a high amount of ethanol, up to 83%.

Which is better E85 or E15?

E15 typically has an octane rating of 88, but is generally less expensive than traditional gasoline, the Renewable Fuel Association stated. Similarly E85 is a mixture of ethanol and traditional gasoline, but has a much higher percentage of ethanol – between 51 and 83 percent, according to the U.S. Department of Energy.

Why does E85 get less mpg?

The drop in fuel economy is because ethanol has lower energy content per gallon than gasoline. E85 also burns faster than regular gasoline because it vaporizes faster. So your engine may eat through E85 faster than regular gasoline.

What’s the difference between E85 and E15 fuel? examined that question in a fuel-efficiency road test of E85, which is a blend of 85 percent ethanol and 15 percent gasoline. With its 15 percent ethanol content, E15 fuel would not reduce mpg enough to erase the benefit of ethanol’s cheaper price, says Bob Dinneen, chief executive of the pro-ethanol Renewable Fuels Association.

Who are the opponents of the E15 fuel blend?

Opponents of E15 fuel also argue that its use without proper controls could endanger the estimated 40 percent of all passenger cars and light trucks on the road today built before the 2001 model year and not approved for E15.

When was E15 fuel approved for use in cars?

Most consumers won’t have to grapple with the problem any time soon. E15 fuel has been approved by the Environmental Protection Agency (EPA) for use in passenger cars from the 2001 model year or later, and it is being promoted in several Corn Belt states where ethanol is a major product.

What are the arguments for and against E15?

In such a case, the real winner would be the ethanol industry, which would benefit from a 50 percent increase in demand if E15 became ubiquitous. One of the chief complaints by E15 opponents is that ethanol (an alcohol) is corrosive to many of the metals, plastics and rubber components used in internal-combustion engines and their fuel systems.
