Mayf,
A few years back I bought a "test mule" Buick V6 from a petroleum lab in
San Antonio. They tested various oils to determine which gave best
performance. I asked which ones were best and the guy told me he couldn't
discuss it because of contractual confidentiality agreements. After we got
the motor loaded, as I was closing the window on my truck, I pointed to the
muscle car in the parking lot and he said it was his. I asked what oil he
used. At the very last instant he quietly said: "Mobile One". That's the
only oil I've used since.
