Not sure if this is true, but i have friends who drag race and they use a straight weight oil becuase the molecules are not hybrid like a 10/30 or 20/50. they prefer like an sae30 or sae40 weight, supposedly under alot of stress the straight weight oil will be alot less prone to molecular breakdown becuase they are bound together better...
if anyone knows this for sure, i mean the guys who told me have some crazy records and race weekly, but i'd still like to know for sure, seems like it would be truthful to me ?!?
