Re: motor oils
The owners manuals, as far as I can remember, have a graph with oil weight recommendations for the climate the vehicle will be operated in. The lowest number to be used in the coldest temps for easier cold temp lubrication. I don't think I've ever seen a zero recommendation.
As far as my old 315,000 miles Tahoe is concerned, I have used 10w30 in it for 12 years and now with the high miles it does use a couple qts between changes. I am thinking a 20w50 might be a good one to use. Might even use a bit less oil too.
