6.4L Power Stroke Engine and DrivetrainDiscussion of the 6.4L Power Stroke diesel engine and drivetrain in the 2008 Super-Duty trucks. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 6.4L Power Stroke engine.
Can jet fuel (kerosine) be used in the new 6.4 that requires ultra low sulfur diesel ? I've run jet A in all my previous ford diesels but this 6.4 seems to go through that " regeneration mode " often if it's running on jet A.

Manual's pretty clear on what you should run. They can't be explicit about everything you can't use; they just tell you what you have to use. Personally, if it were my truck, I wouldn't use anything else other than ULSD.
Jet-A, and the MIL SPEC version JP-8 have 0.06 wt% sulfur. Low sulfur diesel has 0.035 wt%, and I think ultra low diesel has .001wt% sulfur content. So the regens may be related to burning fuel with 60 times the sulfur. Shouldn't harm the engine, but the exhaust after treatments are prolly suffering. You could take them off, but gramp may let go of his hugging tree and come hunt you down with a stick. He don't like nobody missin' with his planet.

Jet A has no lubricant in it at all. You will waste your injectors and who knows what else, in short order. I won,t even use it in my 6.0 for that reason. You might get away with it mixed in an old 7.3 but not in the new systems.

Environmental concerns are secondary to the military. I am designing vehicles using a F-550 chassis with the 6.4L engine for the US Air FOrce that are required to use JP-8 as an alternative fuel. Ford has never tested this scenario, so the outcome for the government and Ford is in question

Hmmmm, so just roll the dice and see what happens then? If the JP-8 is the question what does Ford say? There arent any new military tatctical applications using any of the new diesels...could be an expensive trial run. What are you desigining?

The Air Force is not "required" to use JP-8 as an alternative fuel. However, most AF equipment is designed to run on JP-8 because of availability in deployed locations. this only works because it is JP-8 not Jet -A. Jet A is the base product for JP-8 but the AF addatizes it for use.
They are required to use bio diesel and E-85 as alternative fuels.
Jet-A, and the MIL SPEC version JP-8 have 0.06 wt% sulfur. Low sulfur diesel has 0.035 wt%, and I think ultra low diesel has .001wt% sulfur content. So the regens may be related to burning fuel with 60 times the sulfur. Shouldn't harm the engine, but the exhaust after treatments are prolly suffering.

j/k. I have a CAT and everything on my truck.
JP-8 does not contain 0.3% (3,000 ppm) sulfur; it is limited to 0.3% sulfur.
Actual sulfur content varies according to the base stock it's refined from but is typically a tenth of the 0.3% limit.

It would seem to me that the military has a couple of things the rest of us don't.... Extremely deep pockets is one....
At the same time, it appears that those higher on the food chain have an overwhelming desire to make life miserable for those in the trenches... It would scare the p!ss outta me that you are designing vehicles but have yet to master the shift key.
