Re: Racing Oil

I run 15w-50 racing oil in my 35 Cadillac just because of the zinc. The only drawback for me is that my caddi don't have a dipstick but a floating rod with an indicator in top and because of the heavy oil the float is not very responsive. Haven't changed oil yet in my 36 Packard but I think I will use the same oil.
