Quick Answer: Why Use Ethanol Free Gas

Pure gas gives drivers better mileage. This is because gas mixtures like E10 and E15 have less free energy due to the added ethanol. Compared to regular and premium gas mixtures, non-ethanol gas is better for your overall mileage.

Is ethanol-free gas better for your engine?

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.

Because it is an alcohol, ethanol dries out the rubber components in a fuel system. This leads to cracking and brittle fuel lines, floats, seals and diaphragms.

What is the difference between ethanol-free gas and regular gas?

Ethanol contains roughly one third less energy than ethanol-free (also known as non-ethanol) gasoline does, which means you will get slightly fewer miles per gallon if you use E10 or E15. The fewer miles per gallon you get is small, but measurable. For E15, the amount goes up to 4-5% fewer miles per gallon.

Is gasohol better than gasoline?

Overall, gasohol and gasoline have some similarities and many differences and both impact that effects the environment.

Can you use Rec fuel in a car?

REC-90 is an ethanol-free, 90 octane unleaded gasoline blend designed for use in recreational/marine engines which can be damaged by the ethanol found in other gasoline blends. It is also usable in some aviation engines [1] and automotive engines, though it has not been thoroughly tested for cars and trucks.

Why is ethanol-free gas more expensive?

Each year, the laws require that the number of gallons of blended gasoline increase. As a result, pipelines are sending refineries sub-octane gas that needs ethanol or premium gasoline blended with it before it goes on sale. As refineries start to cut this amount of pure gas, it is becoming scarcer and more expensive.

Is Costco gas as good as Shell?

So the higher the ethanol content, the higher the octane. The octane rating for E15 (15% ethanol) is 88 octane and E85 (85% ethanol) is 108 octane.

Do I need fuel stabilizer if I use ethanol-free gas?
