I have used millers and royal purple racing 41 for the last year on track. AT 120 DegC the royal purle which is the same grade I.e 10 cst and40cst @ 100deg runs .05 barG higher oil pressure than the millers. I know most people in the racing faterintyt on here run millers but just speaking from my experience. I hope this helps
