Back to aviation for a second. Had me wondering about jet fuel in conventional diesel engines. Each morning or before each flight I would take fuel samples from all the low point drains of the aircraft I was about to go for a ride in. Half fill a mason jar, do the swirl test and if the sample was clear and no contaminents present, the norm would be to dump the fuel into the tow tractor's fuel tank. Usually I would guess I poured probably 2-3 gallons. Which by the way aboard the aircraft carrier would be powered by JP-5 anyway. I believe those tow tractors were powered by 2-cycle Detroit Diesel engines, and they seemed quite happy to be running on the jet fuel. Just find it interesting in regard to lubiticity of the fuel.
I ran jet fuel in my '02 7.3 for years without problems. The difference between my 7.3, your Navy tow tractors, and current generation trucks is simply fuel pressure. Our older equipment was more tolerant of poor fuel simply due to the relatively low fuel pressure requirements of the engines. The lubricity is not as critical for lower fuel pressure pumps.
