It is sold at gm dealerships and is about 24.00 a bottle. Just follow the directions on bottle and i guarentee you it will clean all carbon off your valves and pistons. I call it ( miracle fix in a bottle) i have been using it in everything i own since 1998. You will not be disappointed. If you do alot of trolling you will build up carbon fast with our gas being junk that it is you rob your engine of power and rpm's. Try it yiu will be surprisef.

Chevron makes it for GM and calls it Techron when they sell it. It is in their gas already.
