Even if mileage efficiency is reduced by 3%, ethanol-free gas is better for the engine. There have been reports of ethanol mixed gas leading to rusting engine parts. Ethanol, by nature, attracts water and can cause damage. There are gas stations across the U.S. that offer consumers a choice of ethanol vs.
You’re all good—mixing ethanol and non-ethanol gas won’t affect your car. Most modern vehicles are designed to run on gasoline. Minor changes to this formula, such as ethanol, won’t damage your engine and might even improve your gas mileage.
What happens if you mix ethanol free gas with regular gas?
We researched the various types of automotive fuel from multiple professional sources so that you’ll know for sure what this will mean. You can safely mix ethanol and non-ethanol gasoline in your vehicle’s fuel tank. Regular gasoline and ethanol are compatible and mixing the two will not harm your engine.
E85 gas is suitable for use in any vehicle designated as a flex-fuel vehicle by the manufacturer. Cars.com reports that flex-fuel vehicles are capable of running on both ethanol-gasoline blends and regular gasoline.

Can you run ethanol free in a regular engine?
Using non-ethanol gas in your car won’t harm the vehicle’s engine. You can mix ethanol-free gas with ethanol-blended varieties. However, using an ethanol blend may cause damage to your outdoor power equipment.
Which gas should I use for my car?
For the vast majority of American drivers, regular unleaded gasoline is all they need to use. However, most gas pumps also have premium and/or mid-grade gasoline that cost a little bit more, and have a little bit higher octane rating.
Can normal cars take 10% ethanol?

What year cars can use ethanol gas?
Is Your Car Approved to Run on Ethanol? According to a 2017 study, 80 percent of new vehicles sold were approved to run on E15 gasoline. In 2012, the government approved the use of E15 gasoline in any vehicle made after 2001, though not all manufacturers were on board at the time.
Can ethanol damage your engine?
Water-ethanol solutions can damage fuel systems and engines, and the system will need to get flushed to prevent further damage. Once phase separation has occurred, no additive can reverse it, and the fuel tank will require draining.
Back in the old days (pre-1994), E85 could eat away at some engine components. Most vehicles produced in and after 1994 are immune to ethanol. Since 1994, it has been US federal law that vehicles must be compatible with ethanol. So engine damage caused by E85 hasn’t really been an issue since then.
What happens if I put E85 instead of 87?
Continually filling a standard gasoline car with this high-ethanol fuel can result in serious fuel system corrosion. Plus, when you accidentally put E85 fuel in a car, it may void your engine warranty. That means you could be on the hook for the repairs, even if your car is brand new.

If moist air gets into the tank, the ethanol will absorb the water and can lead to running problems and rust. Ethanol can also corrode fiberglass and rubber, often found in classic cars. To keep your classic car in great shape, we recommend filling it with non-ethanol gas.
Does E85 get worse gas mileage?
MPG. Due to ethanol’s lower energy content, FFVs operating on E85 get roughly 15% to 27% fewer miles per gallon than when operating on regular gasoline, depending on the ethanol content. Regular gasoline typically contains about 10% ethanol.
Do you get better gas mileage with a full tank?
A full tank of fuel weighs more, driving round with additional weight in a car or van will reduce fuel economy.
Why is E85 so cheap?
“The reason for that is because the main ingredient in E85 – ethanol – is priced far below gasoline right now. You look at the wholesale terminals where the fuel is blended and ethanol today is selling for about $2.80 a gallon. That compares to gasoline that is selling for about $4.20 a gallon.
It’s potentially damaging. E85 is not corrosive in nature, but does attract moisture; and water is bad news for engines.
It can be costly to retrofit. Vehicles produced before 1987 are not E85 compatible.
Not quite environmentally friendly.
Not as efficient.
Bad in cold weather.
Can you mix E85 and 87 gas?
Yes, you can. Provided your engine is designed to run on E85, you can feed it any ratio of E85/gasoline. You should not attempt this in an engine not designed to run on E85.
Can you mix regular gas and flex-fuel?
Yes, standard gasoline can be used in flex-fuel vehicles.
The engine inside FFVs is designed to run on gasoline as well as other fuels. This generally means gas blended with ethanol and methanol. No matter what fuel you put into your FFV, it’s stored in the same tank.
