But think about this....Rotella is designed to go long, long in a commercial diesel engine and keep it clean and manage soot.
more reason to use this for my track car that runs 11.5:1 AFR in boost. I'm really torn between using this oil on the track because of everyone's uninformed, arm-chair quarterback opinion and the threat or suspicion of foaming with long 4k-7k rpm exposure for 30-minutes at a time. However the UOAs look good.
a built miata motor running 15psi through a gt2860rs, and the car sees track time. 11.5 is rich, but fat enough to compensate for 10% ethanol and keep EGT under 1300*F.
