Aviation Gasoline

Avgas 100 / Avgas 100LL

Product Description

Avgas 100 and Avgas 100LL (the “LL” indicating low-lead) are the principal grades of aviation gasoline in use today. Their specifications are identical in all respects except for lead content and the grade-identifying colour. The two major
specifications defining these grades are ASTM D910 and DEF STAN 91-90. Whilst both grades are designed for 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.

Product Application

Avgas 100 and/or 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 two grades are distinguishable by tetra-ethyl lead (TEL) content and colour (see typical properties table below). Whilst 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 but should not be exposed to the higher lead content Avgas 100 grade.

Features/Benefits

Avgas 100 and Avgas 100LL are manufactured to provide the balanced set of properties required for satisfactory performance in piston-engined aircraft, viz: good anti-knock performance, tightly controlled volatility, resistance to oxidation, adequate low temperature flow characteristics. Avgas 100 and Avgas 100LL are 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.
