It’s like the video from Slick-50 some years ago where they put slick-50 in a mower - ran it for a while and then drained the oil and started the mower up again and ran for a few hours. It was a total SCAM. The oil was NEVER drained.
And as I’ve said before…Amsoil could be the best oil ever made - it doesn’t mean a thing. People aren’t keeping their vehicles over 500k miles.
