It's a good point, thanks Roller for the advice. You remind me of another car I have ever kept. I just warmed the car up every three days without running it. The battery was discharged after one month and the car wouldn't start.I've learned that it is better to run the car than just warm it up. You can drive the car for a few minutes to warm it up. Warming the car will only do good on the machine and not all the parts of the car.
