Half a gallon of engine oil? How big is your tank? I use ~2 ounces of Stanadyne Lubricity formula in my 20-gal CUCV tank.

How much does one of these fuel polishers cost?

I have two 50 gallon tanks. Since it is a Multi-Fuel engine the extra oil doesn't hurt anything.

Their very pricey, that's why I never installed one. I like the idea of a engine oil centrifuge and have thought about getting one many times. Again the cost keeps me from doing it.

For our purposes, a fuel filter and water separator and a pump to circulate fuel through it is all we really need.
If I were buying one today, I'd look at the $40 26GPH Racor SNAPP. Another $40 for a fuel pump.
You can get much fancier and more expensive, but a basic and effective rig can be built for about $100.

In all reality our stock system cleans the fuel pretty good. It is constantly being cycled through the filters. If you go with some modern spin-on filters and a good water/separator ( I use WIX filters) you'll clean the fuel just as well as the Racor system. I know all about the "Racor" filters since our buses have used them for decades. In my opinion their not much better then the WIX filters. A true polishing system (one that uses a centrifuge) is something that a waste oil burner could make better use of then our trucks could.

Would the polisher get the fine particles out of wmo?
It would be interesting to figure out how long it would take to pay for itself.

Right. I thought we were talking about polishing bulk storage of fuel, not in the truck's fuel tanks. If you want to polish the fuel in your truck, you can just run an electric fuel pump on a timer and circulate the fuel through the truck's existing filter and water separator. In essence, the low-end bulk fuel polisher replicates the fuel filter and water separator in the truck. One could even make them identical, so the filter & pumps are interchangeable.
You do the math to figure out the throughput of the pump & filter, and how long you need to run it to cycle all your fuel through the filter. How often you do this depends on local environmental conditions, especially humidity and fine dust.
Some folks use a much finer filter for the fuel polisher than for the stock fuel filter, so their fuel polisher is a separate circuit than the fuel system, with its own pump running on a timer.
I mentioned the Racor because it's only $40 and it has a clear water collection bowl in the bottom, so you can inspect and see how much water is there. There are many other good brands out there.

If you went with a "centrifuge" unit then it would take out most all the particles even down to 1 or 2 microns. Again the cost of one of these units is a bit much for the average user. If you had a complete bulk fuel system and ran "WMO" then I would buy one. For just a small system a simple gravity fed system would work just fine.
