two stage filtering. Using industrial sock filters. 25 micron and 5 micron. I let the oil settle a day or two if it's murky. Some of my collected oil is pretty clear and it goes into the filters right away.
My first 35 gallon batch of veggie I also dumped a gallon of used motor oil into the filtering drum. I will say that the used oil does not stay mixed very long. I'm on the last of my original WVO/motor oil batch. The dispensing drum had a good sludge layer of used 5 micron filtered motor oil in the bottom when I pumped the last of the veggie out and into the car. But I assume any of the used motor oil that made it to the fuel tank settles to the bottom of the fuel tank and is picked up first, washed out with the diesel I add to the tank and mostly burned up by now. Yes it's kinda gooy but the diesel should have thined it out and flowed it right thru the tank screen and fuel filters and burn most of it. Everytime I stopp the motor oil should start settling and thus be the first to get burned up everytime. Thus it's "purged" from the system prety quick.
Ambient day-night temp range has been 70-95 for the last few weeks. A cold front came thru on Monday and dropped it to 50-70. But the car still starts and runs fine in the cold morning. Half way to work it started slowing down again. I pulled over and put 2-3 gal diesel in the tank (spare car in the car) and I was back up to full speed again.
For almost all this pattern, temps have been very summerish. The car has ZERO mods for veggie oil.
Does anyone care to put forth a "vote" for what they think the cause is or what I may discover when I pull the strainer? Kinda like the Heraldo RIvera "Al Capone's vault" thing.
