Seems to have worked for me in the past for inside storage:
* Full tank of fresh gas ( winter mix ) w/ Sta-Bil
* Tires inflated to normal pressure
* Use of Battery Tender or removal of battery if no electricity in off site storage facility and then connect the Battery Tender at home
* Tarp on cement floor to block condensation/moisture
* Not covered, limits condensation build up w/ fluctuating temperatures
*
Oil change
* Liberal placement inside of dryer sheets such as Bounce . Or, use of moth balls, don't know which approach is more effective. If not screened, block the air inlets to engine and inside.
I vaguely remember from an article , if a vehicle is started in the winter, minimum of 1/2 hour run time @ RPM equal to 20 MPH ?
