jet fuel in diesels?

[djg]

I work at an airport. Over the years, I have heard of people running diesel ground equipment on jet fuel. Can anyone comment on this practice?

I have heard of it. It requires an additive that gives the jet fuel lubricative properties. I have also heard that you can add biodiesel or vegetable oil to jet fuel to give it the lubricative properties. The additive that you use for the jet fuel is probably just sulfur, which is what gives regular diesel fuel it's lubricative properties.

I have heard of people who work on airplanes using it to run their diesel trucks. They have to drain aviation fuel out of tanks and their companies then pay to have it disposed of. The managers of the shops let the shopworkers have it for free.

I don't know where the additive for jet fuel is available for sale, but I know that a lot of airports use the jet fuel to run their fuel trucks and other support equipment, since they already have a lot of it on hand. They have to get it from somewhere.

Hope this helps.

In my Dodge Cummins manual it states you can use Jet-A and I believe kerosene for emergency fuel.

I used to work for an airline and we used jet fuel in the ground service equipment. The mechanics had us add a quart of transmission fluid to about every 30 gallons of jet fuel. They said there wasn't enough lubrication in straight jet fuel for the injector pump. We ran the equipment on this for years. You could run straight jet for a while if you had to.

I am an A&P mech that does work at a major airline and Jet-A is basically Kerosene, lubricants needs to be added for automotive injection pumps.
We don't use Jet-A in our diesel engines mainly because it is simpler just to use regular diesel.

The military uses jet fuel (jp5) in their diesel vehicles. It reduces the burden of supplying multiple types of fuel to deployed units. I don't know if adjustments are made to the engines though.
