Winter storage - Oil Change in fall or spring?

Quick question where does this acid come from ? (hint there hasn't been any since ultra lo sulfer fuel)
Water ? its a sealed system
I have never seen a expiry date on any jug of oil on any shelf.
Miles are a layman measure engine designers use 'fuel burn in pounds' -the most accurate.
dirt in oil? use a air cleaner sheesh

my manual states 40,000klms and thats when its changed.

WOW. Maybe some of us should look for date codes on the oil before we use it, as it may already be used up. I can't believe it.

12 months and it's over, you have to drop it just after put it in!

I hear you.better yet pull the pan in the spring and look for all those ""etched rod and main bearings" its two days later and iam still LMFAO at that ridiculous suggestion

If you live in cold country or the south then in the Fall. Get's all the acid out of the oil and won't run the risk of etching the main rod bearings.

If in the mid section of lots of freeze/thaw then in the spring before startup. Get rid of the moisture that can accumulate over the months that would tear up the main rod bearings.

YMMV

sorry man with todays oils and engine bearings there is no such thing
what moisture? where does it accumulate and how?

Funny, where I'm sitting it sounds like you know just enough to be dangerous. Get a few more miles under your wheels and we'll talk about these great new engines you speak of.

could you let me know what brand mnotor does this? how many times you have experienced such and what particular years you had such happen
I have been alive 65 years worked as a mechanic and part time Rv tech
for 45 of those years.Owned and operated a engine rebuild shop
and have never seen nor heard of such a thing.

Mike you should change your name to snoop dog cause your always snooping in other peoples business
Look when people say wrong or outrageous things and I call them on it
Like mosture build up in a engine that sits or "oil after a year etches the main bearings" I have to call them on that if that bothers u too bad. please mind your own posts and not mine FB please and thanks

There is some mysteries going with oil and earth rotation, it must happen every 12 months, not 14 or 16 :)

I guess someone has to make money on a schedule basis, just like expiry date on food, stuff has to go out and new one in.
