oil change...

[oj]

Here"s a question that should get an discussion going... Should I change the engine oil in my combine and other equipment before putting it away for the winter, or should I leave it and change it when I pull it out of the barn next spring? Does it matter? BTW I"m not THAT oj!!!!

Putting your equipment away with old oil is kinda like going to bed with dirty underwear.
If you leave old oil sit long enough in your engine it can cause damage to your bearings from the acids in the oil.
And I'm NOT getting into the dirty underwear part.

Good question. I've thought about that myself. I always figured moisture from freezing and thawing would create sweating in the block. I always change in the spring, but I'm open for discussion.

4010Guy is thinking like me- change it at the end of the season and get all the chemical contaminants out. I'd give serious thought to changing it again at the beginning of next year to rid myself of the condensation that has built up over the winter.
Oil is cheap compared to an overhaul or untimely repair, in my humble opinion.

I have seen rod and mains that had what looked like worm trails in the babbit from leaving the old oil in over the winter and never run until spring. Change the oil after the last use and run it for a short while before storing it.

Oh Yes,

And if I still end up having too much time on my hands, I'll change all the staples in the fence posts around the pasture too. :>)

If the oil is so contaminated and corrosive that you can't leave it in all winter you should have changed it a long time ago.

Sorry,

Just couldn't resist. :>)

I always change oil BEFORE storing anything for an extended period. The acids in old oil will eat into the bearings.

That's about the best one I've ever seen on underware.

I agree with Coloken-if the oil is that dirty-why? I change the oil when I get ready in the spring so I have fresh oil when that motor has to work for me. Why change oil in the fall and then start the engine and contaminate the new oil befor you even use the engine. If that old oil will cause damage from being so dirty then you better flush out that motor if want clean oil when you start it again.

I agree with the train of thought of changing it in the fall just before putting it up for the winter.Why take the chance of there being any corrosives in the old oil sitting there all winter.

Worth it or not, I have always changed mine at the end of the season and it's ready to go come spring. If I run it enough, it gets a change in mid summer...it works out to once in June and one in November. I couldn't care less about the hours.

That would be my fear,that there would be condensation in the new oil by spring.

Well this is an extreme case, but it does go toshow what acid in old oil can do. The trctor (Allis WD) that I rebuilt a few years ago had set for up to 25 years. There was no oil in the pan, plug was in tight. When I cleaned the pan good I saw why it had no oil. There was several pits and one had gone all the way through the pan and let all the oil drip out. I had to weld up several pits as well as the one that went all the way through. As I said, this is in the extreme, but I wouldn't want to leave old oil in an engine forany length of time. Condensation? Well it could happen, how about draining out just a little at the start of the season, any water would be at the bottom. Any tht didn't drain out should evaporate if the oil is running up to temperature.

That little condensation will not do as much harm to that motor than leaving all that acid in there for the new oilk to mix. And this will happen unless you flush that motor. When that old oil drains out guess what is left behind clinnging to the inside of that motor. I'm thru.

 

[LenND]

Hey fellas! I got a way to settle this. You change yours your way and I'll change mine my way. Been doing it in the spring on all our motors for 60 years and have never had one blow up yet.

Why not just change it every 3 months like on a car? Oil breaks down even while the tractor sits. Just a thought.
