Yeah I use Seafoam on all my cars. 1/3 bottle through the intake, 1/3 bottle in crankcase, and 1/3 bottle in the fuel. Then you go WOT all over the place. It will create a TON of white smoke behind you, but it basically burns off all the deposits in your motor. I think its made of petrolium so it makes your car run insane hot, so thats how it burns off the deposits. Make sure you change your oil after the treatment
