Rotella T6 looks like some awesome oil, my Audi's motor being both direct injected and turbocharged, it's really hard on oil. Rotella T6 still looked good after 8300 miles! I also run this in my Honda Superhawk motorcycle, Cummins diesel pick-up, and a 400hp 74' Corvette. Considering running it in my 2010 Corvette too, though it specs 5w-30.
