* Engine life is reduced. If using this type of fuel is unavoidable, changing the engine oil
every 50 flight hours is crucial. Please consult the manufacturer on which type of oil to use.

uids for Rotax Engine.
IMPORTANT!
Four-stroke engines should only be powered by unleaded fuel, for lead sedimentation inside the en-
gine shortens its life. Provided you are unable to use unleaded fuel, make sure engine oil and the oil
filter are replaced every 50 flight hours.
WARNING! Use of fuels with alcohol content exceeding 10% is not permitted. See Rotax
specification - please refer to SI-912-016 “Selection of suitable operating fluids“ latest issue.
NOTE Please refer to the applicable Rotax operator’s manual for additional engine operating limi-
rations.
