At the risk of starting a huge debate, just what is the purpose of seafoam ? All modern oils and gasolines contain detergents to reduce sludge. I'm a strong believer in preventive maintenance. None of my cars, even when they hit 200k ever showed any signs of sludge buildup. A buddy of mine took his valve cover off on a honda with almost 300k on it and there was no sign of sludge buildup. So, what am I buying with seafoam? Again, not starting a debate, just wondering.
Wonder no more. You are buying the peace of mind that you DID do something to keep you engine(s) running nice. Will it help? Who knows
