Thought the title would bring you in How oftern should I be starting the engine..........and how long do you leave it running for? Reason I asked it that the alarm and the radio/CD player drains the engine battery in about a month. Anyone any tips or rituals they go through to stop this? Boo P.S. with my van being mostly static how often should I be giveing her a run out just to free all the brakes/barrings etc...?
