SERVICE INSTRUCTION
2)
Fuels were verified as good at the time of our release.
We reject any liability if the fuel manufacturer changes the composition of the fuel.
NOTE: The Anti Knock Index (AKI) is valid for fuels according to ASTM D4814, and
for fuels which are defined by AKI instead of RON.
NOTE: 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.
