Driving a vehicle regularly not only keeps the battery charged, but also prevents the engine and other mechanicals from drying out. If a car sits for too long, oil starts to settle, fluids begin to separate, and seals can begin to dry out, which, according to Montoya, can cause damage to your vehicle.
Taking your car out for a brief drive helps to keep fluids circulating and ensures all the moving parts — the transmission, brakes, and so on — stay well lubricated. That's one major reason that going out for a drive is superior to simply idling your car in the driveway.
As for how often to drive your vehicle, Kosilla said once a week "is amazing, but once every two weeks is totally fine."
"When you get into three or four weeks [without driving], there's a whole host of things that can go wrong," Kosilla added.
