I appreciate the appreciation. I mostly just post the stuff because it helps me stay on track and not get off on another new project lol. If you couldn’t tell, I have too many ideas and too much time to come up with them.

To satiate some curiosity, my filter system will be relatively simple. I have the Bauer 20v/120v transfer pump which will have some kind of screen or cheesecloth over the intake to mitigate large debris. It will then push the waste oil into a fuel filter/water separator, which will be the ones I replace on the truck itself (coming off the truck and going on the filter system, just to save me some moneys). The fuel filter filters down to 14 micron and of course pulls out any water. From there it’ll go to a simple whole house sediment filter which filters particles down to 5 micron, and from there it’ll go into either a clean jug (oil jugs from changes) or straight into the tank. I’ll be connecting the two filters with 3/4 pvc so I have something solid to hold on to while pumping. Some folks filter down to 1 micron out of an abundance of caution but the factory fuel filter is only 14 micron so I figure 5 oughta be a plenty.

All in the components have cost me about $70 not including the transfer pump, which is only about $100 when on sale. I have 3 vehicles including the one diesel so I have a fairly large amount of waste oil, and I have a couple buddies that tend to keep their waste oil as well (we all use it for treating wooden tool handles and other such things like fences or trailer boards) and they tend to accumulate it faster than they use it. My one buddy probably had 30 gallons waiting for me.

I intend to only run a few gallons per tank of diesel, mostly just so I don’t have to keep buying $13 bottles of diesel kleen lol
