ExxonMobil commercial-fuel , New Guinea

Product Description

ExxonMobil Aviation Gasoline is leaded fuel satisfying the requirements of ASTM D910, Standard Specification for Aviation Gasolines and DEF STAN 91-090 (DERD 2485). Critical properties must be controlled within defined limits for Aviation Gasoline to comply with ASTM D910 and DEF STAN 91-90 (DERD 2485) specifications. 

ExxonMobil supplies one grade of Aviation Gasoline: 

Aviation Gasoline 100LL (dyed blue) is a lower lead version of Aviation Gasoline 100 (0.56g lead /litre Max). It is excellent for use in piston engine powered private, commercial and military training aircraft.  Aviation Gasoline 100LL has been approved by the major aircraft engine manufacturers for use in aircraft engines originally designed for operation on the following grades: 80/87, 100/130, and the discontinued 91/98. This grade is generally available in most regions worldwide. 

Note that properties critical to aviation use (for example, vapour pressure and cleanliness) are not controlled to the same degree in automotive motor gasoline manufacture and handling. ExxonMobil Aviation does not support or approve the use of Automotive Gasoline as aircraft fuel.


ExxonMobil Avgas 100LL meets the following industry specifications:
