I will agree with that. If Kirk uses Syn-Lube and has good luck with it, hey, no problem. I prefer a good name brand oil that is API certified. I have a hard time buying products from a vehicle trunk (the old speaker scam comes to mind). I really would not have a hard time with S-L-4_life, if the website was not from 1996. Anyone with a little computer knowledge can make a decent site with DreamWeaver and cold fusion.
I prefer a quality oil that I can find on the shelf.
