Using 0w30 or 0w40 oil?

[Thomby]

Is anyone running 0w? I know we have the choice of 5w30 or 5w40 depending on how hot an environment we're in, but in either case a 0w should let it lubricate better on cold starts, where a lot of wear occurs, right?

That is a wrong assumption and it is a nearly endless discussion in the respective "Oil Threads" in dozens of "Oil Forums"
Stick with your 5W30 unless you're in very hot or very cold environments.
