My engine's (2000 mazda 626 2.5L V6) operating temperatre is around 100C.
Looking at the data sheets from mobil1 I wonder how much horepower(given that my engine produces 170HP at 6000RPM) will I lose or gain by using M1 5W-40(0W-40) or M1 0W-20(currently in the car) this summer?
Their respecive viscosities for 100C are:
M1 5W-40 cSt @ 100ºC 14.8
M1 0W-40 cSt @ 100ºC 14.3
M1 0W-20 cSt @ 100ºC 8.4
How does higher viscosity rob engine of power? Does it show only at higher RPM or troughout the power band?
I have done 3UOA so far you can see results here:
