Just a quick recap: Out of the hundreds of people on here who have tried Seafoam, there are FOUR (to the best of my knowledge, I've read the entire Seafoam thread) who don't like it. MGDFan, Labnerd, Faster150 (because he prefers B12), and Mattineer, who somehow managed to mess up his F-150 Oh, and some newbie who claimed to fry a 2 stroke by using Seafoam in it.

 

I've always thought I got good results from it. Smooths idle and throttle response.



Sea-Foam Deep Creep is also my favorite penatrating fluid. THis stuff works better than ANYTHING I've used before. Have not broken a single bolt since I starting using it. It foams up and soaks into threads.
