Not to hijack, but I just want to try to understand something.
Folks say 0w30 is 'too thin' in some climates, but my understanding is that viscosity really should be reversed. It isn't 0w at startup and 30 at operating--it's more like 50 at startup and 10 at operating. So no matter what, oil is thinner at operating temps.
So why the hesitance from some folks to use 0w30 over 5w or 10w? Isn't 0w still technically too thick at startup, and thinner is better for startup flow? Operating viscosity should be functionally similar no matter what--so being thinner at cold temps is universally better, right?
