Re: Which V8 engine oil?

OK I'm confused now. Hadn't known anything about the removal of zinc from our oil. For that matter I didn't know the oil contained zinc. I run a 327 with 58000 miles on it and use 10 W 40 oil right now. Should I go up to 20 W 50 ?

BTW, Changed the cam and lifters in my Dad's 51 V8 Studebaker back in 1966 because two of the lobes on the cam wore flat. Funny thing, The problem with that car didn't show itself until the plugs were changed once. The engine started firing back thru the carb. The old plug was fouled so the bad cylinder didn't try to fire. When the plugs were replaced the bad cylinder would try but with a perpetually closed exhaust valve the fire didn't have any place to go except back out the intake when the intake valve opened again. Had to pull the plug wire off To stop the firing thru the carb. That old Stude still drove pretty good on 7 and after a wile 6 cylinders.

The 51 Stude was my first drive in movie car.
