Bob

Thanks much for this info ~ sounds like maybe some more InfoDigging couldn't hurt when it comes to the RedLine

GearLube issue.

I'm still sticking to Valvoline, though, until some info pops up saying its bad thing to do. I've gotten enough good

answers from them to feel like they pretty much know what they are doing & their Lubes are Ok for my VDUBARU.
