Oil Question...

[Tripps]

Hey guys.. I've been running some full synthetic Mobile 1 15-50w oil in my car for a while, and winter is now approaching, the car is increasingly harder to turn over in the mornings when it is cold.

I live in Salt Lake City so it gets fairly chilly with lots of winter weather, I've contemplated switching to a 10-30 or 10-40, maybe even a 5-30 or something close. Does anyone have any suggestions?

Thanks!

Many guys have used 10w30, or 5w-30, and one quart of 15w50.

I'd generally stay away from full 15w50. It's too thick.
