Q: Gasoline

asked by on

I started running my car on 100% gas but my son tells me I won't find it on my trip to California..will it hurt my engine to switch back to 10% ethanol ..what's the best gas to use ? So confused !

My car has 13500 miles.
My car has an automatic transmission.

Hi. Your Kia Sportage should be rated to use regular unleaded gas that is 10% ethanol 87 octane or higher. It will not hurt your car if you go back to using 10% ethanol gas while you are on you trip to California.
