AVGAS 100LL Low-Lead Blue Piston-Engine Aircraft Gasoline

Avgas 100LL (the "LL" indicating low-lead) is the principal grade of aviation gasoline in use today. Its specifications are identical in all respects except for lead content and the grade-identifying color. The two major specifications defining these grades are ASTM D910 and DEF STAN 91-90. 100LL is designed and used primarily in larger, turbocharged aircraft piston engines, the low-lead Avgas 100LL can also be used in smaller, normally aspirated engines which were originally certified on Avgas 80 and where Avgas 100LL has been certified as an alternative fuel.

Avgas 100LL can be used in aircraft spark-ignition piston engines, for which the engine manufacturer has approved this grade of fuel. Although having the same performance in terms of anti-knock ratings, the 100LL grade is distinguishable by its tetra-ethyl lead (TEL) content, 0.56 gPb/l and Blue color. Engines certified on Avgas 100 will happily operate on Avgas 100LL, engines originally certified on lower performance grades such as Avgas 80 may perform well on Avgas 100LL.

Features

Avgas 100LL is manufactured to provide a balanced set of properties required for satisfactory performance in piston-engined aircraft:

Good anti-knock performance

Tightly controlled volatility

Resistance to oxidation

Adequate low temperature flow characteristics

Avgas 100LL is manufactured, stored, distributed and delivered under the most stringent quality assurance procedures to ensure that only clean, dry, on-specification fuel is supplied to aircraft.
