Oil changing intervals question?

[goeduck]

Very true! Now doing 5000, and even 10,000 mile oil changes!
Oil filter every time.
Times have changed, for the better, concerning environment, and performance!
Great point!

That is a lot of miles for a tractor.

Lol! Yes it is!
Sorry, should have said for new cars and trucks!
Sure wouldn't want to be on my tractor that long!

I change the oil & filter on my tractor every 100 hours or every fall - which ever comes first. Been doing it that way for 35+ years and seems to be just fine for my equipment.

Clean fluids and filters are the first line of defence for keeping your equipment running well for a long time.

100 hours or once a year, whichever comes first.

To comment on some previous posts, in 2017 we now have to deal with things like exhaust gas recirculation (egr) on our Diesel engines. This creates more soot, that gets past the rings and into the oil. This subsequently can cause sludging that can ruin your engine.

Thanks! News to me!
Very nice to know now.

Go ahead, be stuck in the past. I'll bet those 100 hr oil changes have also prevent stampedes of wild elephants across your property.

Some of the same exhaust that came out of those cylinders is being routed back in. How has this clean exhaust suddenly become dirty and harmful? btw if you want to boost the engine's thermal efficiency and fuel efficiency , a blocking plate across the EGR port will do wonders.

I don't quite see your point buickanddeere but I've never seen elephants on my property and I'm somewhat partial to the maintenance schedule recommended in my Kubota operators manual.

Why such a mean post?

The egr reduces the burn temps in order to prevent the production of nitrous oxides (pollutant that causes ground level ozone) but also causes more soot. As a result it痴 then necessary to have a particulate filter (DPF) to collect the soot, which is also a pollutant. Then as the dpf plugs up, it痴 necessary to perform a regen, usually by far exhausting fuel into it or spraying directly into the dpf through a separate line. This burns the dpf clean restore exhaust flow.

So to answer your question, the egr causes the exhaust to become dirty.

The end result is, the life of the Diesel engine is significantly compromised and the pollution is released all at once instead of gradually during operation. Seems logical.
