As to cold..not quite as cold as Daryl..but 2010..drove to West Yellowstone Montana..left Bozeman it was -38F..by the time I got to WYS it was being reported on the local radio anywhere from -62F to -64F...never shut my vehicle off while I was there..refueled, added some addl gasoline antifreeze to the tank and made it the 90 miles back home..felt miserably cold
