That's why I posted here.
I thought it was pretty much snake oil. But I watched those two videos, and now I wonder.
It made a real difference for the tractor engine. Tractor engine being larger, like a truck engine, and not just a lawnmower engine, but still different in ways from a truck engine, I wondered if it would make that kind of difference for ours.
Looked like the longer it ran, the better it did.
My engine could use that much help. Doesn't need much. But I would be happier with a bit more compression...

I have read about others having good results as well.
Was just kind of hoping someone here has had some experience with it.
