It has a slightly different freezing point of -40[degrees]C compared to -47[degrees]C for JP-8.
JP-8 and F-24 are completely interchangeable fuels for all CONUS operations.
CAUTION: NAVAIR 00-80T-109 (Aircraft Refueling NATOPS Manual) contains special procedures that must be followed when it becomes necessary to defuel aircraft that have been fueled with the emergency fuel JP-8
First, we established a new and more accurate "apples to apples" pricing comparison, which was adopted as the new standard by the two agencies necessary to enact a switch from JP-8

In this study, we examined the contributions of dermal and inhalation exposure to naphthalene, as a marker for JP-8

The Department of Defense completed a 20-year phased changeover from gasoline-based JP-4 to the safer and more versatile kerosene-based JP-8
