I read on Wikipedia:

JP-1 was an early jet fuel specified in 1944 by the United States government (AN-F-32). ... It was also known as avtur.

Is AVTUR the same as JP-1 fuel, and the term "AVTUR" is just a nickname?

    $\begingroup$ AVTUR stands for AViation TURbine Fuel and is equivalent to JP-1, at least in the UK. This might help. $\endgroup$ – Simon Mar 31 '15 at 13:49

AVTUR stands for AViation TURbine Fuel and is equivalent to JP-1, at least in the UK and in as much as JP-1 no longer exists. I believe that the US military equivalent is JP8 which is Jet-A1 with additional additives, which differs from commercial Jet-A only by a lower freezing point.

Here is the relevant NATO Def Stan (Defense Standard) for Avtur with is the same defstan as for Jet-A1.

This link to an Exxon document gives a great deal of information for various aviation fuel oils.

[EDIT]

From here:

JP-8 is the military equivalent of Jet A-1 with the addition of corrosion inhibitor and anti-icing additives; it meets the requirements of the U.S. Military Specification MIL-T-83188D. It is the dominant military jet fuel grade for NATO airforces. The UK also have a specification for this grade namely DEF STAN 91-87 AVTUR/FSII (formerly DERD 2453). NATO Code F-34.

    $\begingroup$ I suspect this answer is confusing JP-1 (which is obsolete and no longer used) with Jet A-1. The military kerosene-based jet fuels are JP-5 and JP-8, while JP-4 (the old USAF jet fuel) is a wide-cut fuel... $\endgroup$ – UnrecognizedFallingObject Apr 1 '15 at 1:02
  • $\begingroup$ @UnrecognizedFallingObject That wasn't my intention and I've re-read the answer. I can't see where the confusion is. Please point it out to me. Thanks. $\endgroup$ – Simon Jul 14 '17 at 5:16
