Since my car is probably going to be sitting for a while waiting repairs, how often should I go out and start it up and let it run? Right now I've been starting it every other day and letting it run for about 5 minutes. Is this enough, not enough, more than enough? I just don't want to get stuck with a dead car before getting it fixed. Justin |
