The oil tank has a capacity of about 3.2l.
Replace the oil filter when changing the oil. Use suction to withdraw spent oil
completely.
Ecofly will install an oil bleed screw upon request.
The difference between the maximum and minimum oil level amounts to about
0.5l.
Note: While topping up oil, ensure that the oil level NEVER exceeds the
max. level indicated on the dip stick.
Withdraw excess oil by suction if necessary.
The air-exhaust system of this engine is sensitive to excess oil; excessive oil
levels may even result in irreparable damage to the engine!
