Ya . . . but keep in mind that there is an amount of
COMBUSTION ASH suspended in the oil pan BELOW the pump pick-up . . . I don't understand what you mean.

Used oil is very dirty!!!!!
You are fooling yourself if you think that used oil is not dirty or in any way "clean". Automotive filters only filter to 20-30microns in cheap filters and maybe as low as 15microns in a premium type filter. Even the very best bypass filters, and bypass filters are NOT common, only get to maybe 3-4micron at best. Diesel fuel filters are commonly 2 MICRON!!! So the "clean" used oil you are putting in your tank is LOADED with crap that is all at least sub-10micron. Soot suspended in diesel oil is SUBMICRONIC, meaning simply smaller than a micron per particle. All these particles floating around in the fuel system may or may not harm the pump and injectors but to claim they aren't there is foolhardy. Filtering the oil to the 2micron level likely is sufficient. Hydraulic system filters are commonly available in this rating. RT

npnye,
And why wouldn't this ash, that is suspended in the oil as U say, not mix homogeniously with the other oil in the crankcase as the oil is sloshing around in the crankcase as the car is going over bumps, skidding around corners, rapid decelerations and jack rabbit starts and all the time being pumped throughout the engine? Some ash may settle when the engine is stopped and allowed to cool but it is soon mixed with the oil as the oil heats and the car is driven. P E H |

Cummins and others used to sell a machine to do this, it pumped the old oil out, filtered it and pumped fuel also to mix the two thouroly before pumping back into the tanks, about 6 gal to 300.
The old dark fuel we used to get in Mexico had more power than ours, and #2 has more power than #1 so I see no problem but 60% is a bit much, thats almost bunker fuel, and starting a 17 deg.? |

Would this work to filter the oil?? .. uses a roll of toilet paper to filter it. I saw one of these in action and the guy took used diesel motor oil and ran it through the filter and it came out clean and clearm ( oil looked like new)

On my 1982 - 300SD - Turbo Diesel I had mixed for few times used hydraulic oil when making oil changes in hydraulic systems of machines.But with me increase of mileage wasn't happen.Then I stop to do so. I was reading about of the hydraulic oil and the article says that it is extremaly low flamable then I assume that this is the reason for mileage not changing with this mixing. I try also a used light lube oil but not passed through heating condition as motor oil. The results was the same: Not difference in miles/galon. Some comments?
