Oil Type

Ah yes, the can of worms has now been opened! Believe me when I tell you that you wont get a constant answer. Some will say synthetic, some will say regular, some will say cheap, some will say expensive. Different weight oil IS for different climates and driving/racing styles. Choose what is best for your application.

The valves in your car are mechanical and thus, are before the age of hydraulic valves and "emissions control oil". The oil back then had high amounts of Zinc, or "ZDDP" as the technical abbreviation for it. Get a good racing oil that has these higher amounts of zinc to protect your tappets from ever-so-slowly wearing themselves out.
