Default Re: Best oil for V8

[QUOTE=Flathead Fever;2232151]Because the sulfur and other anti-wear additives have been removed from most oils. I use the Delo 15W-40 "diesel" oil in all my collector cars, flatheads and Mustangs. They cannot remove the additives from the diesel oil because of the extreme pressure the bearings have on them. You need those additives for your flat tappet camshaft.....

This is the first time I have heard a solid reason to use diesel oil in an old car.
