The Ford Barn - View Single Post - Use WD40 to suspend crud in cylinders for removal

I have heard that WD40 leaves a silicon residue that can reduce bearing (and cylinder) life. I was also warned by the guy who installed my power garage door not to lube it with WD40 as it could void the warranty. Remember it was designed as a Water Dispersant not a lubricant.

FWIW I add a little 2-cycle oil to my gas. Don't have a clue if is beneficial - just seems a good thing to do.
