nipper Posted March 30, 2007 Share Posted March 30, 2007 EEEEEKKKK Back away from the additve ..... Anything that says its going to flush or cklean part of your engine is not a good thing. The only thing that seems to work well is seafoam. nipper Link to comment Share on other sites More sharing options...

If you burn it im all for it, if you add it to one of your liquids that you dont burn i'm not. nipper Link to comment Share on other sites More sharing options...
1997outback Posted April 4, 2007 Author Share Posted April 4, 2007 what is better to add the seafoam to the gas or to the injector? and how do i add it to the injector? Link to comment Share on other sites More sharing options...
jamal Posted April 4, 2007 Share Posted April 4, 2007 if you add it to the gas tank it's going to go through the injectors... I seafoamed my car through the pcv and gas tank. It made a lot of white smoke and I think it helped. Link to comment Share on other sites More sharing options...
