There are restrictions of the type of fuel used in Motorcycle Sport in Australia.
Each discipline in the Manual of Motorcycle Sport includes some information on the type of fuels accepted for use in that discipline.
The use of leaded fuel is permitted under certain very restricted circumstances. These are dependant on the discipline. Check the individual disciplines for more details.
From January 2009, leaded fuel passbooks are no longer valid for the purchase of leaded fuel for motorsport. More information can be found here.
Competitors can buy leaded racing fuel or avgas from fuel suppliers who hold, or are covered by an approval from the Australian Government. You cannot buy avgas for non-aviation purposes from airport fuel suppliers unless they are approved.
To buy leaded racing fuel or avgas from an approved supplier, you will need to supply evidence that you are a current member of a recognised motor sport association or club. For Motorcycle Sport, a current Motorcycling Australia competition licence is required to be produced. Leaded racing fuel or avgas will only be supplied in sealed containers with capacity up to 200L, unless otherwise approved by the Australian Government.
Generally speaking, fuel must be purchased from retail petrol pumps of commercial fuel suppliers. Additives must not be used, other than those specified in the relevant discipline chapters of the Manual of Motorcycle Sport.
Other fuels may not be used, unless they are homologated by Motorcycling Australia under General Competition Rule 12.9, as follows:
12.9.5 Homologation of Fuel
188.8.131.52 Unleaded fuel produced by an oil company for sale in the Australian general transport fuel market through retail petrol pumps in at least 5 states does not have to be homologated.
For the avoidance of doubt this means the fuel must be available for sale on demand from a roadside bowser outlet at each of at least 5 separate service stations in each of at least five Australian states or territories.
184.108.40.206 Organisations seeking homologation of fuel must provide MA with:
a) Two 1-litre sealed containers of the fuel for analysis,
b) Details of the fuels characteristics,
c) The distribution network,
d) The price structure,
e) A homologation fee of $2,500 in the first year and $2,000 per year thereafter.
