If its the BG44k stuff, it will work, they use nothing but that stuff at the dealership. They use a special tool, which I think enters the fuel line through the pressure fitting on the engine, injects it through there. But it works. You cant get it on your hands, or it will burn. One of the mechanics told me that when I handled a can, told me to wash my hands soon.

Seafoam will probably work about the same also.
