Hey all! Just bought a 2012 Nitro with a 250 Pro XS. The previous owner has just been putting regular fuel with no treatment in the tank. He said if I started putting SeaFoam in the tank it would due more harm than good at this point since it would dis lodge any hunk built up in the motor and potentially block the fuel supply. Is there any truth to this? What would you guys do?
At the top of this page you will find a sticky, with all of the information you need. But you should be running Don's cocktail in every tank of fuel. From the way it sounds, the previous owner has never changed the fuel lines or filter on the engine. I would recommend doing that for sure, and having the injectors flowed/cleaned. Then you would know exactly what has been done, or needs to be done, instead of the unknown.

If you would, please take a moment to review the Announcements at the top of the Forum, and be sure to provide the Required Info (serial number) when posting. Thanks!
