First of all, it depends where you live. Here in New York at present, we have three different diesel fuels. All different, it's NOT just the color. In some other areas, it differs.
Heating oil grade is what farm fuel was until a year ago. It has the most lube in it, but is now illegal to use in any engine. It is dyed red.
Now, farm and off-road diesel is medium-sulfur with less lube, but not as low as on-road ultra-low sulfur. It is also dyed.
Highway ultra-low sulfur fuel is legally required to have a lube additive put into it - to make it safe for older mechanical injection pumps - like your's.
The main question is - since additive is expensive, are you always going to trust there is enough put into your highway fuel?
Stanadyne Roosamaster, Bosch, and CAV all call for fuel that has enough lube to make no more than 460 microns. The number is just a measure of metal wear. The lower the number, the less wear. So, mechancal pumps are designed for "460 micron" fuel. All the low-sulfur fuel AFTER the additives are put in - is rated 520 microns. That causes excessive wear according to tests. That's why there are so many fuel-lube additives on the market for diesels.
Cheap insurance is to just add some two-stroke oil to your diesel. It is the most cost-effective way to ensure your fuel won't cause premature pump-wear.
Add two-stroke oil at a 200 to 1 ratio, and it brings "520 micron" fuel down to 360 microns. That is pretty cheap insurance.
Stanadyne lube additive does the same when added at a ratio of 1000 to 1 - but it's expensive.

Today's Featured Article - Box Plow Blues - by Tom Schwarz. One of the first implements most tractor owners obtain is the box plow. For very little money, this piece of equipment promises to plow and flatten any hill or vale on your ranch road or farm. At least that's what I thought! As simple as a box plow appears, it can be rather challenging to make work correctly. In our sandy soils of Florida, traction is king. You can never have wide enough tires or heavy enough weights to get all the traction you want … unless you own a monster tractor. U
