I've stuck with 0W-40 Supercar, and paid for oil analysis with each oil change. Since I'm averaging 20k mi. per year, I'm doing a lot of highway driving. Analysis results have shown good life remaining even after 6,500 miles, though that is my personal limit for this engine. The analysis is my piece of mind that all is well inside.
