OK OK OK, I know this topics been covered a 1000 time but..I'm changing cams in my stang tomorrow and was wondering if its safe to switch to a full synthetic oil? I've heard many horror stories about seals and gunk in the motor ect...My stang is a carb motor with about 120,000 miles on it. , doesn't somke or use any oil at all. I've never had any problems with dino oil but I can see the new technology in the snthetic oil. Somebody give me the full story.....
