I was curious if anyone has any tips or reasons why I should NOT do this to my car... (2001 GTP w/no engine mods) Also, what are all the benefits and does it acutally help THAT much? Does it ACTUALLY clean out the engine and injectors? And also, pouring it into the fuel... Does it require replacing the old fuel after? Is there a time limit you need to change your oil after you seafoam an engine? Pouring order tips? Thanks for everyone that helps out in any way.
