Was wondering with the cold weather outside, like 9*,[wind chill] day time, likely to be even lower tonight. With the vehicle, 01 mazda, with over 160,000 miles, running good. Anyway car will sit till Monday, is it any good to start and let run for a few minutes, 5 at the most, then Sunday the same? Come Monday temp's will hover once again in the 40's. Here in the mid Atlantic states on the east coast. Maybe better to check tomorrow only, Sunday? huh? Just a concern about battery and being a older car with miles on it.
