Here in the northeast, in a couple of months we'll winterizing and putting the cars away for a long winter's nap. My question is, how many will be changing their oil prior to covering up for the winter versus dumping the oil in the spring. I put mine away with the battery tender and don't really start it more than once or twice over the 4 months.
I change mine in the spring.

I do it in the spring (this is a standard sometimes heated debate). I would not however start the car during the storage months, particularly if you leave the old oil in there... just me.

From the Pacific NW but when I deployed before retiring, I usually knew how much life was left on my oil, so I didn't worry too much about that because the car wouldn't be used on a daily bases.

However, I asked a neighbor who owned a '66 Vert to come over, start and run the engine to normal temps but not drive it. He came over about every 2 weeks until I got back (usually 6-12 months). I did not use a battery tender either and it drove like I never left when I drove it for the first time again. I also poured a bottle of Stabil in the gas tank to keep the gas preserved and not collect moisture in the tank.

With you being near, I believe you can do this yourself without any issues come spring. I can't verify that starting and getting the engine up to temps helps but I remember my Dad telling me that starting the engine every week or so took care of the front and rear main seals and kept internals lubed.

I have an unusual situation. My vert remains at my winter home in Florida when I return to my New England summer home for a few months. I put about 2000 miles a year on the vert and do oil changes every two years just before I put it into summer storage with a battery tender. This year I had to replace the AC Delco battery because it was not happy being on the tender for 3-4 months. Yeah, I know oil changes are recommended every year by the guys who sell oil and service but ...... the vert has not complained yet

New oil before you put it away and if it's staying on the floor, roll it a foot or so one way or the other every month to prevent flat spots on your tires.

I haven't had a winter yet with this car but my Z28 spent 8 yrs hiding from the snow. Stuff your exhaust pipes to keep critters out and a couple of dryer sheets in the car helps to keep mice out.

Very true, I agree

If I storing it for winter I would want clean oil in the car, not dirty oil like others mention.
Clean is better then dirty.

I have driven the car 15,000 miles over the last two summers, in No. Ohio. I run it about halfway through the summer, and change, then again just before I put it away. Clean oil all winter.

The dealer told me they thought the problems w/ oil sensors were due to people leaving dirty oil in in the cars over storage. Made sense to me. I use Mobil 1, nothing's too good for my 'Vette, so what's and extra oil change once a year??

In the old days, it was common practice to change oil in the spring, due to condensation and carburetor engines leaking gas into the crankcase, ether through the carb flooding over or the fuel pump having a bad diagram and leaking gas into the crankcase. Not to mention the oil back then was no where near what we have now and how much cleaner our engines of today run. The is is just a few examples, today I don't think it really matters one way or the other !!!!! Remember oil never loses it's ability to lubricate, it just gets contaminated !!!!

I don't store mine, as long as the roads are still clean I keep driving it. Salt is another thing, then it sits. Change oil as necessary.

Change mine in the spring, but the pre winter change appears to make sense.

Oil is the cheapest thing you'll put into your car to protect it. I no longer have to put it to bed for the winter, but when I did I changed the oil before putting it away AND when I took it out in the spring. I used to put about 3k on it during the "season".

Fall, gets rid of built up contaminates during use.
Spring, gets rid of built up contaminates during non-use.

Now, that was the theory "once upon a time", does that still hold true given todays oils? Someone else smarter than me would have to answer that.
