Does anyone know what has a higher HT/HS between Amsoil 0w-30 and M1 0w-40? I notice Mobil doesnt post HT/HS data on there website..hmmm. I'm thinking ahead to far, but for next summer I want the higher of the two bc my engine runs hot. I have the 0w-30 wt comparisons, but not the 40. Also, Isn't this for Diesel engines?
AMSOIL CASTROL MOBIL

HT/HS 3.5 3.1 3.4
WEAR: .39 .47 .45
