If you are dead set on it , i guess 2 cycle since its designed to burn. But doesn't diesel oil have lubrication properties on its own due to its nature?
Don't think you should ad any oil unless you have a very shi*tty injection pump or injectors.
But I have heard that vegetable oil should be good for additional lube in diesel systems, eg. canola or sunflower. Maybe a castor based 2t oil will be really good too.

Yes it has lube qualities but at a greatly reduced rate now days. Spilt diesel used to attract dust but NOT anymore!
I use TC-W3 oil in my Cummins. The diesel fuel should have additives that provide lubricant. But what is should and what it has are two different things.
But part of the need comes from those having a mechanical injector pump like a Bosch VP44. Its critical that it have proper lubrication. But I cannot say for other injector pumps.
According to the links in a recent thread, a 2% bio-diesel to regular diesel mix did the best in a wear test compared to all the main additives and regular diesel.

cheers!
OK, but you are in Denmark, so do you really know the history of diesel fuel in the USA? You have injector pumps made before they went to ULSD. I think before that it was just low sulfur.
The Bosch VP44 is an excellent injector pump but is sensitive.

1 oz / gallon.
Im adding 8 0z per 75 gallon of fuel
point being any additional lubrication to ULSD fuel can only be a good thing.....
I'm an mmo fan however there was data posted that mmo actually had a negative impact when used in a Diesel engine so even though I love the stuff a Diesel engine is one place where I wouldn't recommend it.
And tc-w3 is cheaper anyways,and made to burn.
No brainer to me.

How many ppm of sulphur is the standard in the us? In europe we have maximum 10 ppm.
The EPA asked the engine manufacturers association what the wear spec should be, and then went with a worse number. You are almost guaranteed longer pump/injector life by using an extra lubricant.
It's one thing for a modern engine but something old definitely has to have some lube.

Factor that in with ULSD and in older diesels you almost have to add lubrication.
Cold winter blends are often a mix of #1/#2 for cheaper blends, up to 50/50. Better fuels do it with additives and you can generally tell the difference in how the truck sounds with the different fuels.
