My 2013 Ford Mustang has been sitting in my Massachusetts garage since around mid November and I have not started it since then. I keep it on a battery tender and I was always taught that it's not a good idea to start a car in storage unless you can drive it to heat up the oil if not you risk developing moisture in the oil and the engine. I have often wondered though is it a bad thing to let a motor sit for more then several months it that the oil will totally wash away from the cylindar walls and you get a totally dry start. Now I also read in my owners manual that if the car has not been started in 15 days it is recommended to start the car and idle it until the motor reaches normal operating temp. So what do you all recommend for storage starting every 15 days or just let it sit for several months until spring? Is one way less taxing on the motor?
