Winter oil change?

Howdy,

Do you fellas change your oil in the beginning of winter?
Then do you change it again in the spring? Or do you just leave it till spring?

Does anyone put reg oil in the winter then back to synthetic in the spring? Seeing as it is cheaper and unused anyway? I was thinking of doing this and not changing the filter until spring?

Do you see any problems with this?

If it's a fresh and recent change prior to winter, I leave it alone....I don't see the difference between the oil sitting in a container on a shelf or sitting in my engine case unused. I do go out and start/run the car for 15 minutes or so periodically during the winter just to keep lubricant throughout and blow some of the condensation out of the muffler.

Wait a minute, Chuck. You don't have not stinkin' winter in Elk Grove Ca. You should be driving it all year

I do all my oil changes in the spring. My car resides in a heated garage all winter long, and usually after the first maiden spring run I change the oil. If you've got really old dirty oil, I suppose the acids and such that build up probably cause some corrosion and would argue for changing out the oil with fresh before winter storage. Then run all summer with what you put in before winter sets in again. New oil is new oil, whether it's been sitting for a few months in the crankcase or not.

Did I just contradict myself? Well, I only put on a couple thou miles each year and figure the oil is not so old as to cause any corrision issues. But I could be wrong.

Or, you could drain in the winter, fill in the spring (if you do not have a long winter and do not need to start the car during that time).

I think winter storage is all that cheap CJ-4/SM oils are good for. You can finally use that Castrol GTX you had lying around.

Doesn't your owners handbook specifically tell you not to idle the motor to warm it up but to drive it immediately? Mine says:

Quote:
Don't heat up the engine in idling. Start at once, however, avoid high speeds or full throttle before the engine has reached its normal operating temperature of about 176 F (80 C).
+1 "You don't have winter in Elk Grove". I logged dozens of skydives at Lodi in December/January/February, never even broke out the lined gloves or the warm clothing.

My winter regime is to fit the Conti WinterContacts, check the screen wash/wiper blades and change the oil/filter every 3000 miles. So pretty much only the tires that are different...
