Ok, what are the benefits in this case?

Bottom line is this- the M103 is a flat tappet engine, you want to risk potential camshaft damage using the latest low ZDDP AND risk leakage AND spend 2x the amount you normally spend?

Makes no sense gents.

Dino oil in these engines is fine, don't fix what isn't broken.
