Re: Seafoam in high mileage engines
It does what it says, but at that many miles, you might want to wait until your just about ready for an oil and plug change. As far as recommendation for use, ultimately, using a quality oil and filter as well as keeping up with maintenance of the air intake and throttle body minimizes, if not eliminates the need for such a product. Also, the older the engine, the more likely you can have fouling or develop leaks. I've used it, noticed a slight change, but AI had all ready disassembled my throttle body and cleaned it.
