I'm retired so how often should I drive the car at minimum?

car has 80,000 mileage and I can sometimes go longer without needing to drive somewhere.

Drive the car at least once a month, to make sure that battery is charged. And drive it for about 30 minutes to make sure that engine gets up to full temperature and the moisture that happens when an engine is cold started is evaporated. I always recommend that if you do short driving, that at least once a week you do the 30 minute drive.
