What I understand about older lubricants... Like ATF and Hydraulic fluid... Back in the 70's it was basically like mineral oil/petroleum based and a few minor additives put in... That way the old tymers where able to put large amounts of ATF or hydraulic fluid in the fuel and get away with it. Not to mention the design of the older diesel engines would comsume just about anything.
Now with today engines and tight tolerances and electronic injection (pumps or injectors) these engines don't tolerate WEO, WVO, or other oils very well without some sort of change in performance and/or effect of life of the pumps.
Like ASH content is really important... Measures inorganic residues - The small amount of non-combustable metallic material found in almost all petroleum products is commonly called ash. Ash content should not exceed 0.02 mass percent. These residues are actually a deposit that will be left behind on the pistons, and combustion chamber...
Then ther is the carbon residue... Measures residue in fuel - can influence combustion. The tendency of a diesel fuel to form carbon deposits in an engine can be estimated by various tests to determine the carbon residue after 90% of the fuel has been evaporated. WEO or WMO tend to be extremely high in this catagory because of the amount of carbon already wasted in the oil...
So... To keep the performance up I would use a clean oil that meant to burn like BIO or 2 Cycle Oil...:Thumbup:
