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.

Civil Jet Fuel

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. 

Military Jet Fuel

Shell Aviation provides a number of fuels for military use.

Aviation Safety Data Sheets

A safety data sheet (SDS) describes the hazards of substances and mixtures and makes recommendations for safe handling and use.

Shell AeroJet

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.
