The assumption's been that since ConocoPhillips is the U.S. distributor for Korean S-Oil's Group III base oils, that's what goes into the synthetic and synthetic blend finished oils blended by ConocoPhillips for sale domestically. I can't say the mechanic who told you domestically available Motorcraft uses base oils imported from the U.K. is wrong, but it doesn't seem to make any sense, either. It makes more sense to me that U.K. Motorcraft oil uses U.K sourced base stocks. But, what do I know?...
I do know that with nearly 1,000 miles on the first batch of buck-a-quart TropArtic 10w30 SM Synthetic Blend I scored at Dollar Tree last summer, my Hyundai 2.7L V6 is running at least as well as it did with my former motor oil: Havoline 10w30 SL.
