recently a friend of mine offered to give me as much aircraft diesel as i needed or wanted. i guess there are aircrafts out there that do use diesel. is this diesel a higher grade version of the diesel our trucks run on, # 2 diesel? would our trucks benefit from this if is an affordable source of fuel?

thanks

Ask your friend what grade it is exactly, ie, JP-8 or Jet-A, etc. Some jet fuels may have gasoline in the mixture.

I think JP-8 is close to diesel fuel in composition, may be "drier" and need a lubricity additive.

Even the owners manual on 12valve engines with the tough P-pump specifically say NO to "CITE" and JP-4.
Like Ruralmedic said, your unknown grade turbine fuels may contain a wider "cut" in the refining process, which could contain much many aromatics like in gasolines (like JP-4).
I'm guessing that your fuel is probably drained civilian JET-A as it likely didn't come from a military base.
My 12v manual says, JP-8, JET-A, #1Kerosene is ok on P-pumped 12valves.. But I'd really think twice if it is going to be run through a VP-44 without LOTs of Stanadyne etc..
At least find out exactly what kind of aviation fuel grade it is.

I'm sure someone else on this site may know better than I just how successful running a VP-44 on JET-A can be.

I hope you can take the guy up on the offer, as free fuel would be quite a blessing!
Good Luck...

I would also like to know. I have two drums of Jet A at home and lots at work to use. What I have read, and what I have been told seem to be diffrent. From what I have read if you have the P pump Jet A is fine sice the engine oil is what lubs the pump. For the vp-44 the fuel lubes the pump so you need to add a 5% lube oil to the fuel for it to work. This is not recamended by anyone of course because no body wants the liability. Now for what people tell me that have jun Jet A is do it. I have met several people that have been doing it for years and have not had a problem. These people work around the fuel or in the bush working on helicopters and this is the only fuel there. One fellow pointed out that the FCU (fuel control unit) on a turbine engine is all lubed with fuel and they last just fine. So I guess you have to choose for your self. I think if you mixed at least 5% lube maybe a little more and mixed it with diesel half and half the engine wouln't notice the diffrence. Your milage will go down but if the fuel is free it just might be worth it too some. If someone here has/does run Jet A let us know how it works for you.


Keep in mined this is for jet A ONLY not Jet B, any jet fuel that contains gas will not work and will DAMAGE the engine.

Well, in the owners manual there are some clear points about not using it. (Not even JetA, except in ver cold weather, no other fuel available, lubricity additive needed etc)
If it's drained fuel you'll want to assure the quality- water and dirt could be in there.

Also if its drained fuel, has it been mixed with other types, ie jp-4, jet-b, jp-8, jp-7.

But think of the amount of heating oil this is going to replace Even if you've got to buy a petroleum furnace.

jj3500

okay...thanks all. guess i got to get one very specific description of fuel.

johnh

try it in your furnace

Something tells me the fuel pump manufactureers are going to have a big cash flow boost in their immediate future. Lets see now, finger nail polish and um, yeah, recycled carb cleaner. That will burn in the Cummins.
Why would you spend thie kind of money you spend on these trucks and burn garbage in them?
