*Engine life is reduced. Should you be forced to used this kind of fuel, change of engine oil every
50 flight hours is crucial. Please consult the manufacturer on which type of oil to use.
IMPORTANT!
Four-stroke engines should only be powered by unleaded fuel, for lead sedimentation inside the engine
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 fuel with alcohol content and/or other additives is not permitted.
