Hxll no! I would never use/add snake oil in my vehicles, PERIOD.
Truth is, almost all the ads on late-nite TeeVee infomercials are basically useless and their only goal is to go after your mullahs.
Conspiracy aside, the ever evolving oil technologies is going alongside (if not parallel/trailing) with the ongoing development of IC engines, and as the standards become ever more stringent, so is the complexity of the oil (blend).Just wait til you read up on the soon-to-be-coming-to-a-store-near-you ILSAC GF-5 standard and you'll understand why.
Bottomline: why the heck you add those infomercial-grade snake oil and assume that it's gonna make your existing OTC (recent API/ILSAC standard) motor oil betta?
Oh, I get it. IT's your money of course....
