5w30 or 10w40
I always seem to remember hearing 5w30 in the winter 10w30 in the summer, but everbody here seems to recomend 5w30 all the time. I already got 10w40 GTX, should I get 5w30 instead? Also what's the purpose of warming the engine up before changing the oil? Sorry for all the newbie questions but this is my first time changing the oil since I got the car last fall (didn't want to lay in the snow to change it during the winter , so I had it done). Thanks in advance.

Warm oil flows better from the crankcase than cold oil does, so it gives you a better drain.
