I've done real life testing in millions of miles with oils in all kinds of vehicles. I could care less about .02 in a quarter mile. I do care how long my motor runs good and how much wear is on the internals. I run conventional oil in everything from a 1966 273 to a 2001 Jeep Cherokee. From 2.0 liter 4 cylinder to a 383 V8. NEVER an engine failure, they all start and run like new with between 250,000 and 300,000 miles on them. I won't run anything lower than 10w30, and that is synthetic in the three 5.7 Hemis in the newer vehicles we own. Sell that BS to anyone that will listen, not me. With my track record, why would I experiment with "new" expensive balony.
