I put it in the crankcase up to two quarts between oil changes. It's basically the cleaning additives that are in very good motor oils.

One quart in my old 350 gas powered chevy crankcase raised the oil pressure from 5-10 at idle to 20 at idle. Started using it at 190k on that truck and have used it since on any that leak or burn a little oil.

Never run it in the fuel. Do use seafoam occasionally.
