can i add fuel octane booster to 87 octane?
or just run the 93 gas? thanks .

 

Sorry, but no - you need to use proper premium pump gas.

Besides, you would spend FAR more to actually get up to 93 octane trying to do it thru octane boosters as compared to just paying the additional 20 cents per gallon at the pump.

There are no shortcuts to quality fuel, or the proper octane. If there were, no oil company would ever sell or even bother to make anything other than the lowest octane.
