Additives are used for ULSD. You could certainly add your own. I'm not sure what would be appropriate, nor how much, but that shouldn't be hard to determine.

I am aware that it is still legal to sell LSD. I don't think it's available anywhere near me. I don't care much either, as long as the 606 pump stays dry. I've only put a couple of tanks of ULSD through it, so we'll see how that one goes.

I know that refiners put additives into pump ULSD. I imagine they also put additives into ULSD #2. When you said this:

...Lubricity is the other issue, although if you're burning LSD #2 it won't be as bad. Once ULSD #2 is delivered (and soon enough you won't be able to get anything else), you probably want to keep it out of your system.... '

I thought you were implying that ULSD #2 wouldn't provide as much lubricity as pump ULSD, though in retrospect I guess your statement wasn't very clear. In any event, *that* is why I was asking about using an user-placed additive: because of what you stated/suggested. I still don't understand, but I appreciate the input.

Back in the sixties, when road taxed diesel fuel was $.29 a gallon and "off-road farm fuel" was $.23, "heating oil" - plain old #2 fuel was $.19. That was when I started burning plain #2 in all of our equipment. We have clocked tens of thousands of hours and hundreds of thousands of miles with no fuel issues whatsoever. Truth is the mileage (or gallons per hour) is noticably better on red juice so when I order for the farm I specify straight #2 fuel - not additive enhanced "diesel" at 30-40 cents more per gallon (I can treat with Power Service for a heck of a lot less).

That said, here in farm and logging country, where half the population has an off road diesel tank in the yard, the DOT has begun dipping the tanks of diesel vehicles (primarily pickup trucks) on a regular basis. I have a 500 gallon tank 3/4 full of red juice sitting out by the barn as I write but I don't feel it is worth the chance to use it in the MB. Actually, depending on where I fill up, the cost of taxed fuel is only marginally more, and occasionally less, than the red.
