Sunruh... since my conditions are NOT normal & ALL racing (RPM range is 6K - 14K), my thinking is that the new Rotella 15W40 Syn blend will be more shear stable. Am I correct? Also just to put this into persepctive I dump my oil after every race weekend, same for track days. This is part of the reason I dont use a more expensive race specific oil as my OCI is so frequent.
Thank you.
