Read your owners manual, run whatever it says to run. Check your gas door...usually on the inside of it it tells you what the manufacturer says you need to run.

 

The higher the octane, the better quality the gas is (usualy), unless they run it through dirty underwear I think your safe running between 87-95 octane
