Synthetic Oil question.

Older engine tolerances are usually bigger then newer ones.
A buddy told me, while he was watching the speed channel, that he heard soon the only oil that will stop friction is the kind you put in or is recommend for a diesel engine.
That there was some sort of chemical being taking out of reg oil because all newer cars dont need the same kind of protection they did before.
Maybe this is why a corvette comes out of the factory full of synthetic.(no doubt a blueprinted engine) Not sure a corvette is a good example for this conversation.

Now this may be an old thread but it is a good one, indeed, and it is what made me join this forum...
I have a project 67 mustang coupe w/ 351 Cleveland and I owned it for bout 13 years. I de-tuned it, the engine, from when I bought it as well we rebuilt it. After it sat in the yard for almost a decade, I started driving it again. (Good starter for my first thread)
We'd always put synthetic in. Even when it had solid lifters.
I wish I knew more what all we are talking about here, I didnt see the TV article that my friend did, and I always thought oil was oil. But if I rob my engine of those big friction protecting molecules and have to scrap it, I will have to sue the oil industry the way smokers sued the tobacco. lol
