2500M: pre-storage oil and filter change?

[Renaldo]

Guys, is there consensus on whether it's best to change your oil and filter immediately before storing (about 5 months, where I live)?

I've heard about acids building up and I guess fresh oil would prevent that.

Or is this unnecessary -- just change it out in the Spring?

Hi you're old oil will have more acids in it than new oil if it's due or nealy new then give it a good oil change and filter before storage , you can get storage oil that is better than standard oil at stoping rust in storage etc, a lot of farmers on you're side of the pond fit winter storage oil in there tractors for the long winter months? But you don't get the damp winters like we do it too dam cold!!!! Richard

You should try the Pacific North West, for eight months. Horrible.

In fact, Chicago was one of the coldest places (in the winter) I've ever lived, but the humidity collecting on my car parts, thanks to condensation from the daily temperature cycling, was the worst.

Wasn't there something about paraffin vs. petro vs. synthetic oils?

Best,

Hi Ron,

I always change for new oil and a filter prior hibernation, whether you have to do in October or March, its the same money and effort. Usually I leave the rest of the annual service till March (laziness.......)

Thanks guys. Snow flurries predicted here for Friday (ugh), so if I'm gonna change the oil out, I better do it quickly.

I have bought a lot of farm tractors , pickups ect from Canada and been totally amazed by there condition , 1940s pickups just been in the back yard for ever and no rust , even after 30 years the engine usually still turn so just thought must be so cold it's dry or perhaps it's better just to leave all stuff out side if it gets damp inside ????

It's true that once it gets cold here, it stays cold. The winters are usually low humidity. And we don't lots of rain in better weather.

(Although we seem to be getting more variation than we used to. Don't know if that's what climate change is doing to us. But I'd find it hard to complain much if our winters warmed up.)

They throw lots of salt on our roads, which of course plays havoc on the bodies of cars used in the winter -- even with our low humidity. I understand that happens in the U.K. too. Don't know about the U.S.

Anyway,I could definitely imagine a vehicle stored outside in the cold here, might fare pretty well.

My car lived most of its life in dry New Mexico, thank goodness, so the frame is solid.

And I'm doing all I can to keep it that way...
