Can anybody point me in the direction of some documentation that can help me to distinguish between these two fuels? I have been searching for hours and I keep coming across articles that use these as sample fuels in experiments, but none that actually describes the numbering convention?

I understand that JP-8 Jet A + additives, but what are the differences between the JP-8's themselves?

I have also see it as JP-8 POSF 3773 and JP-8 POSF 4177.

Any help is appreciated.

The POSF numbers appear to be identifiers for specific fuel samples from Wright Patterson A/F Base, produced by different methods.

This gives the composition of 3773 (and two others, but not 4177).

I suspect there isn't any "numbering convention", except that 3774 is the next sample after 3773.

Presumably WPAB keeps a database ...
