I have an '85 gs and was wondering if it was worth it or not to use octane boost. IF not what would be safe to help clean the fuel going into my tank?

 

No, why do you want to increase the octane? Higher octane does not increase power, or "clean the fuel." I don't know exactly what you mean by that.

 

No increased octane is not worth the money. Why do you want to clean the fuel going into your tank? If the gas is old then drain the gas and put new gas in. That is the only way I would "clean" the gas going into the tank.

 

never put that stuff in your car.....terrible for it
