Well, if the stuff works, it works. That's really all I care about. I know that a lot of bs products have come down the pike over my lifetime, but every now and again, something pops up that's as good as promised.
Be nice is this was one of them. Sounds like great stuff.
I wouldn’t know why running a high quality motor oil or synthetic, suited to your application, couldn’t produce the same results. There are so many specialty oils on the market now, there is something for everyone. I run oil with zinc in it in my old stuff with flat tappets. The racers use it.
Motorkote doesn’t seem like too expensive an experiment. $25 bottle at Amazon treats 2 V8 engines. Can’t hurt to try and see if you notice a difference.
