#185954 So I'm glad I came across this question, I have been wondering this a lot, right now I'm running the valvoline full synthetic 5W-30 (synpower). In the summer, my oil temperatures sky rocketed and now in the winter it's usually pretty stable unless you get on it. I'm also running a Bosch filter at the moment and seems like they a re pretty good, I would never run a fram after what I found on YouTube and d series.

So should I have a winter and summer oil or could I get away with running that 5w-50 all year?
Thanks for all the good info Ryan..... I will read it again
