ASTM D is the major specification covering Aviation Gasoline. and it is anticipated that the Grade 91 will now be removed from ASTM D freeing up. This standard is issued under the fixed designation D; the . last published in Specification D–94 in the Annual Book of ASTM. ASTM D Standard Specification for Leaded Aviation Gasolines.

The second number indicates the octane rating of the fuel tested to the ” aviation rich ” standard, which tries to simulate a supercharged condition with a rich mixture, elevated temperatures, and a high manifold pressure. In FebruaryTeledyne Continental Motors TCM announced that the company is very concerned about future availability of LL, and as a result, they would develop a line of diesel engines.
Is It for Real? John and Mary-Louise Rusek founded Swift Enterprises in to develop renewable fuels and hydrogen fuel cells.
In December Shell Oil announced that they had developed an unleaded octane e910 and will submit it for FAA testing with certification expected within two to three years. They began testing “Swift ” in  And patented several alternatives for non-alcohol based fuels which can be derived from biomass fermentation.
All grades of avgas that meet CANM82 have a density of 6. Certain equipment or conditions of use may permit a wider, or require a narrower, range of characteristics than is shown by this specification.
Archived from the original on 12 March European Aviation Safety Agency. To help solve this problem, the specification for an aviation fuel known as 82UL was developed as essentially automotive gasoline with additional quality tracking and restrictions on permissible additives.
SuperCharge Octane Testing for Aviation Fuels
On 16 Novemberthe environmental group Friends of the Earth formally petitioned the EPA, asking them to regulate leaded avgas. There are other classification systems for military turbine fuel and diesel fuel. Archived from the original on 6 April Fuel-injected engines in automobiles also usually have a “fuel return” line to send unused fuel back to the tank, which has the benefit of equalizing the fuel’s temperature throughout the system, further reducing the chance of vapor lock developing.
Aviation Gasoline dyed green is excellent for use in piston engine powered private planes, most commercial aircraft, and combat-type planes during military training procedures. In addition to vapor locking potential, automotive gasoline does not have the same quality tracking as d90 gasoline.

Archived from the original on 10 July Aircraft Owners and pilots Association. Note that properties critical to aviation use for example, vapour pressure and cleanliness are not controlled to the d91 degree in automotive motor gasoline manufacture and handling. Lycoming provides a list of engines and fuels that are compatible with them.
It is also excellent for use in piston engine powered private, commercial and military training aircraft.
Some certificated reciprocating-engine aircraft still require leaded fuels, but some do not, and some can burn unleaded gasoline if a special oil additive is used. Motor Octane Number min From throughUS usage of avgas declined consistently by approximately 7. Archived from the original on 26 February d91 GUL is compatible with LL and can be mixed with it in aircraft tanks for use.
