Has anyone on the board run Jet A with there DD 8V71? The airport sells it for $3.18 a gallon. We use it on jets of course but I also know it works great on some diesel's. I should add Diesel is $3.55 a gallon where I am at and climbing.

Many years ago we ran Jet A in 6V/53 powerd tow tractors with no problem.
also in our diesel powerd generator sets that were 6/71 powerd.
Never had a problem these units ran for many years on Jet A.

refresh my memerory; jet A is well filtered carosene is it not??????
if so the cetene rating is very low compared to diesel, it would be good fuel in very cold weather thow.
Also, while I am not an expert, I would expect it wouldn't be legal either since no road tax is applied to it. If someone reported you (i.e. disgruntled airport employee, ex wife/girlfriend/friend, etc.) the fines couuld far outweigh any savings. Kind of like getting caught running off road fuel (i.e. farm fuel) in an over the road vehicle.
Disclaimer: This assumes that you are considering running it in an over the road bus. If the 8V71 is powering something else, then disregard the above.

When I worked for Eastern Airlines, we did the same. I have heard some say that it is too clean and will not lubricate the pump and injectors like diesel will; I do not know anything about that though. Our equipment ran fine and we never had a problem with it, even in the middle of winter. Anything we used that ran on diesel got the Jet A.
We used that fuel on the North Slope in the late 70s in everything that ran on diesel, including the heaters and furnaces. It was running about -40 degrees when I saw it last, and it was doing fine.
If you do some checking on pour points of different fuels, I think you'll see that kerosene and jet fuel are two different animals. Jet fuel has to be good down to -75 degrees. I seem to remember that kerosene was good only down to around zero.
The only problem that surfaced was that it was kind of easy to make splash; when it was being pumped into some rigs, the oiler had some hit his arms. He got a pretty good case of frostbight from it, but he did heal up OK.
For what it's worth.

It'll run Ok, but with less fuel mileage since Jet A has a lower BTU rate than #2 Diesel. Hence, you'll be heavier on the throttle. Good Luck, TomC
Jet A will work fine ,especially if you have access to de-fuelled jet-A which can normally be had for free.
If I'm running jet-A through an engine with a diesel injection pump I put in a lubricity additive as a safeguard.
What is de-fueled Jet A and and how do you get it?
Desiel fuel has more oil content than Jet-A, we add a qt. of oil to fifty gal. for vehicle use on the ramp
Just out of pure curiousity,(sp?) what's the difference between Jet-A and JP4? We used JP4 in turbo aircraft engines in the Vietnam era.

Hi Yo Silver!
I think JP-4 and Jet A are about the same, JP-4 may have a bit of gasoline in it but not sure of that.
I know from my Navy days that JP-5 had a much higher percentage of gasoline in it than JP-4 and was too dangerous for civill use.
So defueled Jet A (fuel pulled back out of the tanks, I presume) is "free" from some airports? Hmm.. I recon you'd have to make sure you filtered it pretty good though, since it was backed out of the plane and put into gawd only knows.
Wonder what the legal implications are.. if any. Wouldn't that depend on where you lived? Some places might be more lax than others. What are the emissions implications?
De-fueled Jet-A is as you correctly say pulled off an airplane,usually because the density altitude is too high and the jet is too heavy to take off .the plane is made lighter by pulling fuel off it.By regulation the fuel that is removed cannot be resold to refuel another aircraft.At some base operations (private side of the airport) this defuel Jet A builds up to the point that the airport has to pay a company to come and get it and take it away.If you know someone on the ground crew they will fill up a transfer tank for you.It's great for running all your off highway vehicles and generators that have separate fuel tanks ;D
Back to the important question.. is it "illegal" (and if so, why) to run that in over the road vehicles? Or is it just a matter of the fuel not (possibly) lubricating enough in some applications?
There are a few airports around here, and if they have "free fuel", I'm all over that :)
Technically it's illegal for use in highway vehicles,the strange thing is they do not put a dye in it like red diesel, so if a vehicle was unfortunate enuf to get 'dipped' for red diesel there shouldn't be an issue.Like I said it's great for tractors,excavators and generators ;D
You can always pay the tax directly to Uncle - the fuel would still be free -FWIW
It's only illegal if you get caught. When was the last time anyone with a bus conversion had their fuel checked?
If they want your Social Security number then I would be concerned.
Defuled Jet A question?
When we defuled- Jet A from a aircraft it the fuel went back into a fuel tank truck that was owned by the fueling contractor or airline it was never sold or given away to a 3rd party.

At evergreen aircenter, in tucson az, our local pep boys for 747s and such its called de-puddled fuel, once you remove any fluids from a comercial air plane you cannont replace, so if a plane comes in with 500 galls left in the tank, and the tank has to be drained to be worked on, that 500 galls becomes useless as far as fuel goes once its drained. like the rest of the posters in this fourm state, we also use it in all of our diesel equipment..
