If you are running a oil, you probably dont need the stabil just the seafoam in a maintenance dose (1oz/gal)
You may not realize it, but if you are adding seafoam, you are adding alcohol to your fuel. Seafoam is nothing but alcohol, naptha and pale oil, its expensive for what it is. I can't see treating fuel for alcohol, with more alcohol.
