Here's the UOA I had done of Shell Rotella T6 5W-40, after 3000 miles, and quite a bit of tracking.
Oil type with viscosity - Shell Rotella T6 5W-40 Fully Synthetic
Miles on the oil - 3000, 2 months, 150-200 track miles
Vehicle type/engine - 06 Mazdaspeed6, 2.3L turbo direct injection 70,000 miles
Driving conditions - normal/sprinted, 50/50 highway/city, summer temps 70-90F.
Track conditions - 1 day oil temps @ 260-275F for 1.5hrs, 1 day @ 250F for 1hr, ambient temps 70-90F
It looks like this oil holds up very well to higher temps, and the abuse of being at higher RPMs for extended periods of time. Plus, I'm glad of the wear results on the engine.
