The best way to get residue out of your motor [SOLVED] Asked by Will D. In Alabama How often can I use Sea Foam in order to get all the residue out of my motor?
Thanks for the question Will. For best results, you can use Sea Foam in every tank of fuel to clean fuel passageways and upper engine areas. For oil, we recommend adding Sea Foam to the crankcase every oil & filter interval. Hope this helps!
