Excellent.
I do wonder, if the more efficient oils also help them wrangle every last horsepower out of an engine, due to the oil moving around easier or with less friction, or if that is nonsense.
I've gone the AEHaas route for a long time, inspired primarily by this board, on a long time quest to see the "thinnest" oil I could use without causing an issue and.. as unscientific and not able to be used as actual evidence as it is, I always thought I could feel "more power" - specifically in terms of an engine revving up faster, only change engine oil, or perhaps more freely if that is impossible or easier - on a thinner oil, I'm stuck on HTHS, just occurred to me how that may relate to MOFT.
I've sometimes thrown in a thicker oil, to try to contrast to what I think I know, and, sometimes engine seems to really like that too. So I don't know what to think.
