If you’re using fuelrated at 87 octane or higher and you stillhear heavy knocking, your engine needs service. But don’t worry if you heara little pinging noisewhen you’re accelerating or driving up a hill. That’s normal, and you don’t haveto buy a higher octane fuel to get rid of pinging. It’s theheavy, constant knock that means you have a problem.

What about gasoline with blending materials that contain oxygen (oxygenates),such asMTBE or alcohol?

MTBE is “methyl tertiary-butylether.” Fuel that is no more than 15% MTBE is fine for your vehicle.

Ethanol is ethyl or grain alcohol. Properly-blended fuelthat is no more than 10%ethanol is fine for your vehicle.

Methanol is methyl or wood alcohol.

Fuel that is morethan 5% methanol is bad for your vehicle. Don’t use it. Itcan corrode metal parts in your fuel systemand also damage plasticand rubber parts. That damage wouldn’t be covered under your warranty. And evenat 5% or less, there must be “cosolvents” and corrosion preventers in this fuel to help avoid these problems.
