AVGAS 100LL places greater stress on the valve seats due to its
high lead content and forms increased deposits in the combustion
chamber and lead sediments in the oil system. Thus it should only be
used in case of problems with vapor lock or when other types of
gasoline are unavailable.
■ CAUTION: Use only fuel suitable for the respective climatic
zone.
◆ NOTE: Risk of vapour formation if using winter fuel for
summer operation.
■ CAUTION: Obey the latest edition of Service Instruction
SI-912-016 for the selection of the correct fuel.
