There are several additives on the market that are intended to mix with diesel fuel and add lube for the pump and injectors. Rev-x, Stanadyne, Lucas injector cleaner, Howes, etc. Most have supporters and detractors, depends on who's argument you find most persuasive. If your running an older diesel on ulsd I would recommend adding some kind of lube, a brand new truck should be designed to run with the reduced lubrication that ulsd offers, additives may not be necessary.

Wrong. What about the ash thats left? Where does that go? Like I said, its not meant to be burned.

That doesnt even address what the attitives in the ATF do to the injector pump. Adding ATF is an old school diesel mechanic trick however it does not take into consideration the huge changes that ATF has had in the many years since ATF was first added to diesel.

I wouldnt ever put it in my tank theres lots of other good additives that actually increase lubricity.

Finish reading the post. Just because something isn't designed to be burned doesn't mean that it won't burn. In this case, the ATF will leave ash and contaminants behind. THAT'S the reason not to put it in your fuel system, not the simple fact that the chemists designing it didn't add that use to the label. Anyway, yeah, get something intended to act as a lubricant in diesel fuel.

Certain others haven't posted on this thread yet, figured I'd nitpick Doc's post.:tttt:

So what do you say to guys who have fueled thier truck with filtered waste atf for many miles without problems :pca1:

Here's your sign.

Fixed it for you.
The funny thing is those people always sell their trucks just in time to poor people not knowing what piece of junk they get.
Waste ATF is even more difficult. Just have a look inside an VP and watch those extremely small supply slots. Then take a (working) injector. And see how the plunger slides down the injector stock. It's precision fitment.

Do you really want to disturb that tight clearance with pre-contaminated fluids? The logic must say no. The cheap ass says I don't care- I will sell the truck in time...

In the end it is your own decision (beside from polluting the air with unecessary stuff), your own risk.
Would I buy that truck knowing been driven with ATF? No.

The original question was about filling the fuel cannister with power steering fluid during a filter change. In my experience that's done with new fluid to improve lubrication, probably doesn't get that accomplished, and there are better products to provide lube to your fuel system. Using waste atf, waste motor oil, waste veggy oil, etc. as alternative fuel sources is another question entirely, covered in other threads.

I prefer Stanadyne performance formula. HAd a kabota that wouldnt run right, couch and miss and belch black smoke. Filled the fuel filter housing , ran it for about 30 seconds, and then sit for an hour, came back stareted it up and idled it up to 1250 and after maybe 4-5 min the smoke all cleared up and it ran like new again. Proof enough for me.
