What is the difference between Jp4 and Jp8
What is the difference between Jp4 and Jp8
(OP)
Hi,
I need to know about JP4 and JP8 fuels.
They both are made by blending of kero with additives.
Which one is economically better?

You need MIL specifications or oil company contracts for details on JP-4 (jet propellent 4) or JP-8. JP-4 was a kerosine/gasoline blend. JP-8 is a kerosine based fuel with the high altitude additives. You may buy the Air Force specification MIL-DTL-83133E, Turbine fuels, aviation, kerosene types, NATO F-34 (JP-8), and NATO F-35, and JP-8+100. The cost is about $31 USD. I don't know where you will find details on the obsolete JP-4 specification.

typically composed of about 50-60% gasoline and 40-50% kerosene, is highly volatile, and contains hydrocarbons in the C4-C16 range. JP-4 was the primary fuel of the USAF for decades; however, it has been phased out in favor of JP-8 (see below). When specified, it can contain a full additive package including a corrosion inhibitor, anti-icing, and anti-static compounds. An optional additive is a metal deactivator.
JP-8 was developed to be less volatile and explosive than JP-4. (Commercial Jet A-1 fuel is equivalent to JP-8). In 1996, the USAF completed conversion from JP-4 to JP-8 fuel. It contains a full additive package including a corrosion inhibitor, anti-icing, and anti-static compounds. Optional additives are an anti-oxidant and a metal deactivator.
JET A1 primarily differs from JP8 in that its specification ASTM D1655 does not REQUIRE the three additives that are specified and contained in JP8; namely, the Corrosion Inhibitor/Lubricity Enhancer, the Fuel System Icing Inhibitor, and the Static Dissipater Additive.

JP8 ST, 1995.
