AVIATION PRODUCTS
ExxonMobil Aviation fuels comply with international specifications. Jet A is supplied in the U.S., while Jet A-1 is supplied throughout the rest of the World. Aviation Gasoline (AVGAS) is available on a regional basis. To view the airports at which we can service your fuelling needs, visit www.exxonmobilaviation.com and select the Airport Network tab.
Aviation Turbine Fuels (Jet A and Jet A-1)
Jet A and Jet A-1 are kerosene-type fuels. The primary physical difference between the two is freeze point (the temperature at which wax crystals disappear in a laboratory test). Jet A, which is mainly used in the United States, must have a freeze point of -40 ºC or below, while Jet A-1 must have a freeze point of -47 ºC or below. Jet A does not normally contain a static dissipator additive, while Jet A-1 often requires this additive. Some of the other key differences between the manufacturing specifications within the United States and Europe/Africa/Middle East/Asia Pacific are:
ASTM D1655-05:
• Has a maximum acidity limit of 0.10 mg KOH/g.
• Allows the use of Simulated Distillation via method ASTM D2887.
Defence Standard 91-91/5:
• Has a maximum acidity limit of 0.015 mg KOH/g.
• Allows for the measurement of Total Aromatics via method ASTM D6379/IP436.
• Has an additional requirement for measurement of lubricity for Jet A-1.
There are additional differences between the two primary specifications related to allowed test methods and the reader is urged to seek out the full specification for more detailed information. ExxonMobil Jet A and Jet A-1 are typically produced to the requirements of ASTM D1655 and Def Stan 91-91 standards, respectively. ExxonMobil Jet A-1 also satisfies the requirements of the Joint Inspection Group (JIG) Check List. In all cases, the most recent issue of the relevant specification applies to the product supplied.
Military Turbine Fuel Grades
ExxonMobil Aviation is a leading supplier of military jet fuels (predominantly JP-5 and JP-8 as defined by Mil-DFL-5624 and Mil-DFL-83133, respectively). These fuels are kerosene type fuels made to more exacting specifications than the commercial jet fuels. They also contain unique performance enhancing additives.
Aviation Gasolines
ExxonMobil Aviation gasolines are leaded fuels satisfying the requirements of ASTM D910 or Def Stan 91-90 (DERD 2485). The properties of aviation gasoline are specified to give satisfactory performance of spark-ignition aviation engines over a wide range of operating conditions. ExxonMobil supplies AVGAS 100 (dyed green) and AVGAS 100LL (dyed blue), both of which are excellent for use in piston-engine powered private planes, most commercial aircraft and combat-type planes during military training procedures. Both grades are available in a number of regions internationally.
ExxonMobil Aviation does not support or approve the use of automotive gasoline or diesel fuel in piston-engine powered aircraft.
