I am in the Sunny, sometimes sweltering Sonoran Desert so for me the heat is far more of an issue than any 2 week winter cold stretch. I did decide to go with the VR1 oil and for the summer I plan on running straight 50 in the crankcase and considering a 140 for tranny and diff. The heat here is insane during the summer. Search for replacement diff. hasn't begun yet. Full gasket set first then I'll work my way towards the back, follow the drive train.
What you encountered with the sending unit would not surprise me at all. It did sit in a garage for almost 10 years. Started right up so I would imagine that they at least started it up fairly often and the gas didn't smell like varnish.
