10.2.2) Fuel

The following fuels* can be used.
Due to the higher lead content in AVGAS, the wear of the valve
seats, the deposits in combustion chamber and lead sediments
in the lubrication system will increase. Therefore, use AVGAS only
if you encounter problems with vapour lock or if the other fuel types
are not available.
