Being that yellow jack is from Naples Florida, the car has never the temperatue below the frezzing mark. Now that I store the car here in NE Ohio up on jacks, battery out on a tender with a new oil changed in October going in storage and other oil change in mid March coming out of storage. I was told if you do start the engine during its storage period you should take the car out on the road and get everything warmed up for about after 20 min. so the temperture gauge is reach it operating temp. One other thing I do is placed a 100 watt light buld under the oil pan to keep the condensistation down, does it work? I don't know but it sound good to me.
