Has anyone here got any comments on running aircraft fuel in their truck? Its Jet A which is basically refined kerosene, I don't want to cook my engine and wonder what sort of ratio is good..

 

You need to go to the Bio-diesel/alternative fuels forum and ask there. They will have a good handle on the subject.

 

Alright, will do.

 

Jet A has a much higher flash point than Kerosene. Has been known to stretch head bolts. I know some say they do it,,, I would never be so foolish myself.

 

Howdy,

The flash point for #2D is 100-125*F

Kerosene has a flash point of 95-150*F, JP-8 100*F, JP-5 140*F, Jet-A/Jet-A1 Is similar.....



I don't know if I would call that much higher.


Diesel fuel is normally winterized at the refinery level with Kerosene.

Kerosene is used at many airports to fuel (diesel) airport equipment ......the US Army and USAF have used Jet A/JP8 in diesel fueled vehicles, and other equipment for many years.

The main issues with using Kerosene type fuels in a diesel engine are the slightly lower lubricity and there's usually no road tax paid on it.....Other than that, it's not much of a problem......


Kerosene also has a very slightly lower BTU content but I doubt you could tell unless you put the engine on a dyno.

So has United Parcel Service, at least with the JP8 fuel................ with engines certified by the manufacturer to be compatible, one example; properly calibrated T444E/7.3s with split shot injectors.

 

I served on a diesel powered ship when I was in the Navy. They forced us to take on JP5 at one terminal. In order to burn this with out damage to the engines required changing injectors.
On the other side I see no reason to want to do this. Jet fuel has fewer BTU's per gallon and cost more then regular diesel. You would use more of it to do the same amount of work because of the lower BTU content.

 

We burn JP-8 in every piece of diesel powered Marine Corps equipment. All different makes of diesel engines too. CAT, Perkins, AM General, John Deere, etc.

 

Yes, it's slightly lower in BTU/gallon.

I REALLY doubt anyone would be able to tell much difference in a truck or car though... with #2D having a BTU content of about 140,000/gal and #1D/Kerosene/Jet fuel being at about 135,000btu/gal.....it's a small difference.

You would probably only see the difference on a dyno.

It would be worth it if it was free though.....(and it would be a good idea to add some sort of oil for additional lubrication)

 

Thanks alot for the helpful information. You guys rock! I'm running a small amount of light oil with a 1/4 jet per tank. Seems fine. On a similar topic, does anyone know the scoop on this Diesel Secret Energy - Alternative Biofuel Biodiesel Is it or for real??

 

Sounds like a scam. I wouldnt waste your money or my own.

 

adding lubrication is the key, when running jet-a , 2cycle low ash formula 1oz per/gal should be more than enough, have ran 200+ gallons with no ill effects . im not sure how a fuel with lower btu value and similar flash point of no#1 diesel/kerosene would stretch headbolts.

 

Thats what I was thinking, looks a little too slick..

 

to all,

i have friend in the commercial plumbing/boiler repair business, who fuels all his diesels with 1 part kerosene to 2 parts filtered WMO.

all together he has well over 600K total miles on that mixture, with no evident ill effects on the trucks.

unlike some here, i'm NOT an expert (nor do i play one on TV) but his practical experience is why i'm planning to go to that mixture exclusively on our "farm use" Ford IDI PUs. - especially with diesel about to skyrocket in price again.
(farm vehicles, in the states where we have land, are allowed ANY fuel for "farm registered" vehicles, w/o road tax.)

has anyone here had any different results on a WMO/kero mixture?

yours, TN46

 

At ast in Michigan, kero is about 2x diesel, thats why I burn diesal in my kerosene heaters. kero is too expensive for me to put in my truck. You all must have a verg good source of kero
