Re: synthetic oil comparison
Had a S/S buddy tell me of a recently developed Valvoline Synthetic racing oil...says it has added zinc and other additives to keep our dinosaur BBC's alive & well...I don't have a bottle in my hands yet, but hope to nab some soon and I'll report back. Otherwise, sounds like it's eeny-meenie-miney-mo to pick your oil, then dump in a moly additive or a bottle of GM EOS...
