You are definitely right about the behavior of 20W50 at 0 F, Craig. I
use it here in Central Oklahoma, where 0 F might be the absolute lowest
for an entire winter, with 20 F being a much more common daily low.
We've had several periods of five or six days continuously below
freezing this winter, and folks are going nuts (they forget other cold
winters that have occurred). Since my camper is strictly for camping, I
don't have to drive it when it is that cold. I did try to get a 15W50
oil, but distributors here only have synthetics in that grade, except
for a Citgo brand (forget the name of the oil, but it is from Citgo). I
don't see the point in paying for synthetic oil when I am going to
change it at 3000 miles, anyway. Should I? My experience says not.
