What's a good break-in motor oil for a new Ford crate motor?
Synthetic? Old skool non-synthetic? Recommended weight?
Thanks

You’re probably talking about GM-EOS.... I’ve not seen it in quite a while but it may still be available... As I recall it was a Moly-Zinc based product..GM has an excellent break-in additive you can pick up at the dealer for newly rebuilt engines.
