What kind of oil do you guys run in the winter?

I was thinking about running a lighter weight oil for the winter so it can warm up faster but am kinda scared to change it.

Also for whats its worth what do you run in the summer time?

I run 20w 50 castrol all year, and have done so for ever. I think it is mild enough here not really worry about. hope that helps.,

I don't have a 1st gen, but I do have a 1st gen FSM.



Hope that helps.

Wow thanks dDub, I am an idiot I ran 5-20 all summer and last time I changed I only had 10-40 so thats what I used, judging by your chart that makes me a newb, ohh well now i am running 10-40. Did i **** my engine up this summer by putting the most opposite oil i could in, it never once overheated or even got near overheating so idk it seems fine.

It's probably fine, just run the correct weights from now on.

i ran castrol gxt 20w50 all year round, in both my 1st gens and 2nd gens, then my dad ran his old 1st gen with same stuff for the 15 yrs he owned that one.

I run 10-30 year-round. Thicker oil robs horsepower, decreases fuel economy and gets mighty thick in the cold weather. I can see a turbo owner running 20-50 in the summer months, but otherwise it's pretty phycho in our climate. In stock racing classes, we typically run 0-16. On the street, anything-30 is fine, particularly if it's a synthetic. Going thicker is just thowing money away and not providing any real benefit.

EDIT: I don't much care for 10-40 due to the way in which they extend the viscosity range. 10-30 is much better, in general.

Since I have my omp blocled off and the fact that it is cold and Washington really doesn't see too many temp "extremes" I have made the swap to 10-30 and haven't had any issues. Warms up quicker which has been nice since I have to daily drive my 7. I have always used "quality" oil in any of my vehicles anyhow. By "quality" I mean oils that have a petroleum base and not the parafum (wax) base that some of the cheaper oils have. You all know what wax does when it burns (leaved residue, adheres to surface it melts to).
