P66 uses a lot of SK lubricant grp 3 base oils for their motor oils (kendall, motorcraft, shield choice) as well.P66 base stock is hydro processed in Grp2/Grp3 … (others crack)
Conoco is the E&P branch
ChevronPhillips makes several levels of base stock that includes PAO
MC is about like any other semi - but obviously a focus on Ford owners.
Since Grp2 base stocks have become better - calling something semi opens the lower cost production door.
For example around two dozen blenders buy XOM’s EHC - wonder why ?
(there are semi’s posing as synthetic too) …
