I've had my share of troubles with waste oils, both veg and motor oil. After ruining a crappy rebuild pump I took it apart and found that mainly the transfer pump was worn pretty badly. I also went through two Holley red pumps that I was using for lift pumps, one burned up the motor and the other was worn and the motor got weak. I switched to a Hummer electric lift pump and no issues so far. What I found was particulate in my finished fuel. I ran it through sieves to check particle size as well as looked at it under a scope, I had particles as big as 8-10 microns. This lead me to take a closer look at my filtration setup which consists mainly of string wound filters 20, 5, and 1 micron. What I learned there was oil was pushing past the filters by going around the ends. I diecut felt to solve that problem. Next I got a large filter housing for a semi truck with replaceable elements and use that as the last stage of my filtration. Now my fuel has nothing larger than 1 micron and the amount of particulate is minimal. I expect this to solve the problem. As far as actually running the fuels I blend with D2 according to the weather/season running about 50/50 WMO/D2 in winter. The truck starts great and runs great, plenty of power. I think a centrifuge would be a huge benefit and plan to build one this winter. I found no signs of corrosion or other damage in my old pump. At the end of the day I prefer WMO to WVO. Storing and working with WVO is a mess and it spoils, causes mold to grow if not cleaned up, etc. WMO is just messy but easily cleaned up. I use the spent filters as fire starters for my burn barrel out back.
So to answer your question I think the IDI will handle WMO just fine IF you filter, filter, filter some more, check the quality of your filtration, filter again, and then filter again LOL. In other words just get the particulate out of it. Also I built a cold upflow processor to separate particulate and any potential water. This works pretty well. I added 5 speaker magnets to the under side of the drum which I have on a stand to grab any ferrous material. I have a bottom drain to clean it out periodically. My waste oil now is 100% used Rotella T 15/40 from a trucking company, they change it so often it's really clean and has zero water in it.
