I worked with a few guys that had 7.3L Ford Superduties. They would filter used transmission fluid and used that for years instead of buying diesel. Not sure it has the lubrication a high pressure common rail system needs though.

Interestingly enough, the old B-series cummins were originally designed for farm tractors.

With the newer diesel engines, electronic and emission controls, I would not mix a witches brew and pour it in the tank. The engines are designed and calibrated for diesel fuel.

6.6 Military vehicles have no emission systems so it is easier to tweak the CPU to run on almost anything.

they have a EGR system and CPU what is that?? you mean ECM and I can install programming into mine with EFI live like I do now , they get the same factory programming as you and I. Nothing is changed for fuel type. we had a military truck in the shop a few years ago and we did look at the factory tune, (owner wanted a custom tune) we made a few adjustments and off he went, like EGR code off and he installed a blocker plate

But the hardware aka high pressure pump,injectors have to be able to run reliably with it. Programming means nothing if a pump fails due to fuel.

And what type of fuel do you burn in your truck?

ATF was not designed to be burned as fuel. When burned in a combustion chamber it leaves deposits that are not found in diesel fuel or products designed to be burned.

I was not the only mechanic running Jet in their diesels, 2 dmax`s, 3 fords, and 8 dodges most of them were common rails. Our line equipment (diesels) all run on jet, we even have a common rail tug, and A/C 3 Phase power cart with a 6.7 that runs on jet.
