...because you are supposed to mix them with 10w-40 when higher viscosity range is desired? Just wondering if this is the intent of oil companies. I just used 50/50 10w-30 and 10w-40 in an oil-burning Hi-Mi Mitsu because I was reluctant to use just 40 weight. Makes some sense to blend, right? ![[I dont know]](/forums/graemlins/dunno.gif)
