Maybe a stupid question, but my engine builder recommends 20-50 Valvoline, which I run in my 427 FE. My garage is not heated and the temps are in the 35 to 40 degree range here in PA. Will I run the risk of snapping the
oil pump shaft or spinning a bearing if I try to start my engine in these temps? The reason I want to start it is a friend who owns a car dealership wants to put it in his showroom which is heated and I would like it in the controlled environment and have the extra space in my garage.
