It works Fine!
After searching the web and reading various forums I decided to filter down some old sump oil I had sitting around. I started with a pure gravity feed through a 1 micron mesh bag - and mixed it with ordinary diesel at ratios up to 70% oil to diesel.
All ratios below 30% show no difference at all. At 50% oil and diesel, the "nacka nacka" noise of the tappets shut up and the engine had marginally better power available in the low rev range (800 to 1100 rpm). At 70% oil in the diesel, I started to blow a little smoke when under power (Such as 3rd gear and up a steep hill). As I had never blown any smoke at all prior - I backed off the mix to 50:50.
I've run about 500 liters through the vehicle so far - and it seems to love it.
So - can we do it? YES
Does it harm our engines? Only if not filtered properly.
The existing oil filters on the vehicles are a bypass type that clean around 80% of everything going past to around 25 micron level. According to the Automobile Standards Association, some 70% of all engine wear is caused by particulate down to 4 micron in size.

to start tracking the info down for yourself. There certainly is a lot of info if you are willing to do a little research.
Mercedes Benz themselves took a fleet of demonstrator vehicles to China and added 2 stroke motor oil to the fuel at a 200:1 ratio to overcome the damage being done by low sulphur diesel.
As my vehicle has over 530 000 kilometers on the clock - and I love my truck - I want to look after it. This is a good choice in countries where the laws around using diesel alternatives are not structured to win tax dollars. [It is my understanding that folks in USA are risking a form of tax evasion by using the much cheaper marine grade diesel - which is what this is. Home hrade 'heating oil' is oil and diesel -- which also works just fine. It was used here after WWII as an alternative fuel and cost WAY less than commercial diesel.]
I have a donor vehicle that I'll be taking the fuel tank from and installing in my DD as an oil fuel tank. I'll run a centrifugal oil filter to recirculate the oil (direct from my local mechanic) to the tank. I'll use the spare water / sediment filter and fuel lines before an electronic gate valve tapped into the existing lines before my injection pump. Switch over is best done after a few minutes when the engine is warm. I have noticed that the vehicle is very slightly more difficult to start on ratios above 50%. It never gets below freezing here anyway - so pre heat will not be an issue for me.
Motoring at half the pump price! LOVE IT!
