Just wondering the best motor oil to run in below freezing weather and who has different opinions? It gets down to about 6* in the winter here and Im concerned about my oil pressure at start up. I have a 10:1 compression 306 built up if that makes any difference?

5W-30 would work just fine also - make it a little easier on the starts

The first number in the oil weight, the 5w, 10W, 15W, ect represents the cold weight, which in the winter you want to be a low number. 5W-30 and 10W-30 are the same at operating temps but the 5W30 flows better when cold. I run Mobil 1 Synthetic 5W-30 and an oil cooler.
