What weight oil do you run in the winter?
 

I was thinking about putting in a different weight oil the next time I do my oil change which is in about 3 weeks when it's due. What do you winter season guys use? And do you still use synthetic in the winter or regular plain oil?

Around here it's okay to use 5w30 all year, so I do. If it gets colder than -30 you won't find people outside anyway. But it gets colder than a witches tits in Bahstin so you would probably do well to consider a 0W for the winter.

In areas that are really freezing most the time 0w is recommended by the manufacturers.

I run Mobil 1 15w50 all year. Cranks a little slow in the winter but its all I trust with my setup.

I seem to recall your setup is ... non-standard. Let it warm up before standing on the gas and it'll probably be fine.
