I thought what you were saying was that the diff' between Hot 15w-40 & Hot 10w-40 was giving you a 10PSI drop at speed ~ Theoretically, because they are both 40s they should produce the same results ~ you are correct that you have to put something in there so if you try them all & they all vary then you use the one that varies the least ~ but bottom line is I think I misread what you were trying to say.
