What fuel should I put in my car?

It is better for your car to use 87, 88 or even 91-octane gas than to go too low. If you have a luxury car that needs premium gas, try to fill up before driving to a high-altitude location in case you cannot find a gas station that provides the octane you need.

Is it bad to run premium gas?
