Hey guys, I was speaking recently to a mechanic friend of mine and he was telling me I could probably benefit from doing a professional carbon cleanse . It's some kind of machine that runs a chemical or solvent through your engine and collects the exhaust . He says that any engine with about a hundred grand on the clock could stand to have carbon buildup removed and that I"d notice an increase in power. They charge $125 where he works versus $250 at dealerships. I've never heard of this before but I don't consider myself all that savvy in the mechanical knowledge realm. What do you men know about this ? Thanks for the input.
