1967 Chevy II Nova with a 327 Small Block and a mild cam. What type of oil is best

[Dan]

with this engine? wght.grd? I would like to find out what other types of oild you all think would run best in hte engine

[mikey]

With that small an engine you should use a low viscosity synthetic oil so it can ooze into all the tight places. Probably Mobil 1 in 5W30. If that causes it to knock, move down to 10W30.

[Ron I]

It depends how new the motor is I have a 73 gmc with a new 350 and i
use a good 10/30

[Chevelle]

I have a 69 Chevelle 454 thats pretty performance oriented and I go with 10W 30. It would be alright in yours, I really doubt your gonna be running it when its 30 F outside. But buy Royal Purple, yes i know its more expensive but it really is the best oil for these older engines and performance engines. It will also give you a slight boost in HP (about 1-5hp) just because of less friction.
