A.W. go with 20w-50 Valvoline that has zinc in it. A Pontiac engine builder, and his dad who's also an engine builder, said to use in in my 66 GTO's 400 he built. I've been using it faithfully, along with a Purolator L30005 filter. No problems at all.
No 10w-40 Valvoline here either. Only High Mileage 10w-30 semi synthetic. I've stocked up with 5 5 quart jugs just in case that disappears too. I refuse to use any other brand because of all the paraffin in them. Yes, that's where the sludge comes from. Which is probably why synthetic oil was born.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
