Currently have a leased vehicle that I daily drive. The lease is up in early spring and I do not plan on purchasing it. About a month ago I couldn't pass up a 2012 Scion xB with just under 20,000 miles on it for a price I could not refuse. Really like the vehicle. Has the little 2.4 and has tons of room for how small it looks. I am way under mileage on the lease so I do not drive the xB much at all. It just sits in the garage with a tank full of fuel (non ethanol) and some SI-1 in the tank. We get super cold temperatures here, like -30F last winter and am wondering how often I should be driving the xB. I have always heard that a car sitting for long periods is not great for the vehicle, especially in extended cold temps. Is once a week enough for 30 or 45 minutes or a couple days a week? Hoping this isn't a dumb question. Thanks guys.
