Also dont forget there is no longer the oil additive in oil that used to be in there to protect tappets, since everything is now roller in the Automotive world and it's no longer needed, they dropped it.

Diesel oil and some high performance stuff still has it, so just use diesel oil, (or synthetic) it just has a little more soap to keep the engine clean, and that's not a bad thing.

MOST OIL HAD ZINK. NOW THEY DONT. ONLY KOHLER 10W30 AND AMSOIL DOES THAT I KNOW OF.

I checked my notes and for those that want to know the additive's offical name is "zinc dialkyl dithio phosphate " or ZDDP. also found that Comp Cams recommends useing Shell Rotella in high performance applications this is Shells "diesel" oil.  Or again, synethic is fine.
