Grades and Specifications
Aviation fuel grades
Shell Aviation fuels fall into two basic groups:
- Aviation gasoline – Used in reciprocating or piston engines.
- Aviation turbine fuels (jet fuels) – Used in turbo-fan, turbo-jet, and turbo-prop engines.
Within these two groups, avgas is split by octane grade and jet fuels are divided into civil and military grades.
|Fuel types||Fuel grades||Usage||Comments|
|Aviation gasolines||Avgas 100/130||Small piston engine aircraft.||A leaded fuel.|
|Avgas 100LL||Small piston engine aircraft.||A low-lead version of Avgas 100.|
|UL 91 and UL 94||Small piston engine aircraft.||A version of Avgas 100LL with no lead.|
|Civil jet fuels||Jet A/A-1||Turbine aircraft.||Jet A is only available in the USA, however, Jet A-1 is widely available outside of the country.|
|TS-1||Turbine aircraft.||The most commonly used jet fuel type in Russia and the Commonwealth of Independent States (CIS) states.|
|Biofuel||If compatible with a particular aircraft, certain biofuels can be blended into other jet fuels.||This falls into the same grade structure as other jet fuels because it is made from a different source. However, it is not a separate grade in its own right.|
|Military jet fuels||JP-4||No longer used by the military.||N/A|
|JP-5||Military aircraft carriers.||Used by NATO air forces, including the USA and UK.|
|JP-8||NATO air forces, including the USA and UK.||The military equivalent of Jet A-1.|
Aviation fuel specifications
All our aviation fuels are produced to stringent manufacturing specifications. At every stage between refinery and aircraft tank, fuel quality is checked. Through sampling and laboratory analysis we ensure the fuel conforms to the requirements specified for the grade when it is delivered to the aircraft.
Our Shell Aviation quality assurance system is organised on a worldwide basis, made easier because we provide the Shell Aviation service directly in many countries – something no other supplier of aviation fuel can match.

AFQRJOS Check List for Jet A-1
The Joint Systems Checklist for Jet A-1 is maintained by JIG Product Quality Committee on behalf of the industry; Shell has held the long-term chair position for this Committee. The current edition can be obtained from the JIG website.
More in aviation fuels
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 a high energy content.
A safety data sheet (SDS) describes the hazards of substances and mixtures and makes recommendations for safe handling and use.
Our Shell AeroJet is a premium aviation fuel offering major benefits to pilots, operators and owners of turbine aircraft in Canada and Brazil. Shell AeroJet minimises or eliminates problems previously associated with the build-up of water in fuel tanks on business jets, turbo-prop aircraft and helicopters.
