Avgas

Single propeller plane flying above water

ExxonMobil Aviation Gasolines are leaded fuels satisfying the requirements of ASTM D910, Standard Specification for Aviation Gasolines and DEF STAN 91-90 (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 two grades of Aviation Gasoline: Aviation Gasoline 100 (dyed green) is excellent for use in piston engine-powered private planes, most commercial aircraft and combat-type planes during military training procedures. This grade is available in a number of regions internationally.

Aviation Gasoline 100LL (dyed blue) is a lower lead version of Aviation Gasoline 100 (0.56g lead/litre Max). It is also 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, vapor 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.
