Aviation Fuel 100LL

Avgas is used in small piston engine powered aircraft within the General Aviation community. Predominately activities such as private pilots, flight training, flying clubs and crop spraying. Piston engines operate using the same basic principles as spark ignition engines of cars, but they have a much higher performance requirement.

In today’s General Aviation community there are only two main Avgas grades (100 and 100LL low lead) – a rationalization that has enabled us to continue supplying a market that would otherwise have become uneconomic.

This grade is the low lead version of Avgas 100. Low lead is a relative term. There is still up to 0.56 g/litre of lead in Avgas 100LL. This grade is listed in the same specifications as Avgas 100, namely ASTM D 910 and UK DEF STAN 91-90.

All equipment and facilities at Skeerpoort Verspreiders handling avgas are color coded and display prominently the API markings denoting the actual grade carried.

Jet A1

Today’s kerosene jet fuels have been developed from the illuminating kerosene used in the early gas turbine engines. These engines needed a fuel with good combustion characteristics and high energy content. The kerosene type fuels used in civil aviation nowadays are mainly JET A-1.
