The next strategy is to never change the oil. There really is not any need too. Upon every start up, I always check the fluids so they are always topped off with fresh oil when they start getting low, and I change the filters. The filter change is where the impurities get taken out.
People have scoffed and said this is stupid, but is it? I run my cars and trucks for 250,000 miles! That is 84 oil changes I saved, over 105 gallons of oil, and $1700 in oil change costs...PER VEHICLE. Now total that up by the number of machines I have. Again, the railroad turned me on to this, and it really makes sense fiscally and envionmentally speaking. Changing oil is one of those things from a by gone era when engines were inferior and made out of inferior metals. Today it just is not needed.

All oils decompose, changing viscosity and ability to lubricate and cool.

As far as freight locomotive diesel engines go, they are almost never shut off, most are just set to idle and run via fairly sophisticated engine management systems monitored via GPS link to a head office. At least that's what they do here.
As a consequence, they don't see a lot of wear.

American locomotives have 8 throttle positions, so the engines are constantly changing in RPM, though on such a big engine, that is not a lot of RPM's. I think full throttle was something like 900 RPM. The diesel engines still hold a LOT of oil. I think the engine oil capacity is around 238 gallons of oil.
If people do want to change oil, you could always take the oil and dump it into the diesel fuel and just burn it up that way. You cannot dump 5 quarts into a the seven gallon tank of a Kubota tractor, it would be more like 5 quarts in a hundred gallsons of diesel fuel, but will dillute the oil enough to burn it. Before switching to no oil changing, we used to do that on the railroad; drain 238 gallons of oil into the 5000 gallon fuel tanks and burn it up.
As a side note: my career was strange in that Tug Boats use locomotive engines, so after getting done for the railroad, I went to work as an Engineer on Tug Boats. I used that experience to stay dockside, working at a shipyard building Navy Destroyers where I retired.
Digest Oyster Mushroom will digest oil spill, so I would have that as a perimeter border.
