We recently moved to NE Washington from Florida and the idea of winterizing a car is something new to us. We plan to escape the winter by heading to Baja with our truck camper. We'll be leaving behind a small car and maybe a motorhome (if it doesn't sell by then). I've been searching the web for information on winterizing cars and have gotten conflicting information especially in regards to the battery. Do I need to remove batteries or can I leave them on (maybe disconnected). We do have a battery charger but we'll have more batteries (one in the car, in the RV and 2 extra RV deep cycle batteries) than it would handle. The weather here can hit 20 below or maybe even a little colder (although it's been getting warmer every winter). As hubby is disabled, I'll be in charge of winterizing and I'm not really looking forward to lugging all these batteries to our basement. Vehicles will be sitting outside on dirt driveway.
Also....which is best....getting an oil change before storing them for the winter or when we return and why?
Appreciate suggestions. Thanks!
