I'm sorry but diesel weren't designed to run on straight waste engine oil or even high ratios of it. I seen several people take older trucks and do it but... No one has ever come forward claiming that the vehicle last a long period of time without major failure! As a matter of fact this is one of the things that is muted (not talked about) out on most forums is that most of these truck have had major IP pump issues, Major injector(s) issues, cold starting problems, filter plugging rapidly, Severe loss in MPG and/or HP/TQ numbers.

Fuel Specs. straight out of the Owners Manual...

Working our way down the list...

VISCOSITY - WEO/WMO in high amount exceeds the lmitations of viscosity of the fuel this is why Cummins allows up to 5% by volume of WEO/WMO to be used but no more. At 128:1 ratio you not altering the viscosity very much if any... Also remember that WEO/WMO has a centistoke rating well in the 100's !!!

CETANE - Engine oil and 2 cycle oil is a natural cetane reducer. It will increase the BTU's of the fuel but if you go too low you'll make the cetane level to low and performance will start to suffer. This is another reason to limit you amount. This why I limit to 128:1 ratio.

WATER & SEDIMENT - There is going to be metals and other materials in the WEO/WMO that can't be filtered out easily nor removed by magnets. This will increase wear on your fuel system. Since 2 cycle oil is vigin its clean and has no water or sediment...

CARBON RESIDUE - WEO/WMO is full of carbon residue. Since 2 cycle oil is virgin it has little to none carbon residue.

FLASH POINT - WEO/WMO has a extremely high flash point and has a direct bearing of burning characteristic of the fuel. The flash point of 2 cycle oil is closer to that of diesel fuel.

ASH - WEO/WMO is full of ash. Ash is 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. This is why ASHLESS 2 cycle oil is safer.

Here is a WEO/WMO heater burn after 24 hours of use... That's what ash looks like...
