Has anyone compared the same grade conventional and synthetic of the same brand VOA's: ie 5w30 Pennzoil Platinum, Pennzoil conventional, Quaker State HP/ Quaker State Conventional, VSP/Valvoline conventional, Mobil 1/MC5K, etc?
From what I've noticed (some are obvious):
Syn- Grp 3 or 3/4 mix base oil, higher TBN, same Calcium & Zinc
Dino- Grp 2 or 2+ base oil, more Boron & Moly
There is more, but with the quirky search feature I have tried to gather VOA data to include in this post.
Was too much weight being placed on the base oil of syns to use lower moly and boron (pre moly price hike) than in dinos?
