I'm a bit concerned about this issue as I just put in new injector nozzles in the engine and I kind of want them to last. There are, I'm sure, many additives out there, but I read somewhere here in this forum an article someone posted about vegetable oil's added lubricity. Anyone knows if this would be a good idea, and how much would it be necessary to add per tank?

Some where in our threads is a chart showing a test done by Spicer on some of the additives.
A percentage of Bio Diesel (I cannot remember the percentage) had the lowest Wear Scar, meaning there was less wear when it was used.

Your Injectors being some what like over engineered Pressure Relief Valves are less prone to the type of wear that was being tested than the Fuel Injection Pump.

How long your Injectors last has to do mostly with the area on the Pintel and the outer Nozzle body where the two seat. The Pintel goes up due to Fuel Pressure and a the Injector Spring pushes the Pintel back down onto the seating areas.
That beating of the seat is what wears out the Injector Nozzle.

Also with the beating of the seating area is if anything like Carbon (one of the reasons correct IP timing is needed and the same with the correct opening pressure; if correct they help keep Carbon particles out) or Dirt get trapped between the seating areas when the Pinel comes down and hammers little dents into the seating area.
(Fuel filtration helps keep harmful particles out also.)

Lastly not unlike Water erodes the ground the high pressure flow of Fuel erodes the Steel around the seating and Nozzle hole area.

As little as B2 will help a great deal, B5-B20 is even better. The less nasty petrodiesel the better

Vegetable oil has extremely good lubricity... you can blend a little of that with diesel easily, as a additive. Cheap and easy to get.
