JP-8

A type of jet fuel essentially similar to jet A-1 commercial fuels with a full military additive package. JP-8 is essentially highly refined kerosene. It is safer than JP-4, with a higher flash point, slower flame propagation, and lower vapor pressure. It ignites at 37.8°C, whereas JP-4 can be ignited at temperatures as low as −29°C.

JP-4 is described as a "wide cut, gasoline type" fuel, whereas JP-8 is more like kerosene (much less flammable than gasoline).
It may be needless to point out but there are stores of JP-8 stateside and quantities of JP-4 overseas, and this entire fuels picture from refinery to fuel tank is well controlled by the appropriate specifications.
In the case of JP-4 and JP-8 standard test fluids - Type I (for JP-8) and Type III (for JP-4) - are used.
