Manufacturer's description

ExxonMobil Aviation Gasoline is a leaded fuel satisfying the requirements of ASTM D910, Standard Specification for Aviation Gasolines, and DEF STAN 91-090 (DERD 2485). Critical properties — including octane rating, distillation range, vapour pressure, freezing point and oxidation stability — are controlled within defined limits to ensure compliance with both specifications. ExxonMobil supplies one grade, Aviation Gasoline 100LL (dyed blue), a lower-lead version of Aviation Gasoline 100 (maximum 0.53 mL/L tetraethyl lead), excellent for use in piston-engine powered private, commercial and military training aircraft. It has been approved by major aircraft engine manufacturers for use in engines originally designed for grades 80/87, 100/130 and the discontinued 91/98, and is generally available in most regions worldwide. Because properties critical to aviation use — such as vapour pressure and cleanliness — are not controlled to the same degree in automotive motor gasoline, ExxonMobil Aviation does not support or approve the use of automotive gasoline as aircraft fuel. Key specification limits for Avgas 100LL include a minimum motor octane of 99.6, minimum supercharge performance number of 130.0, vapour pressure between 38.0 and 49.0 kPa, and a freezing point of -58°C maximum.
