Do not operate this engine over densely populated areas. Do not operate this
engine over terrain where a safe, power off landing cannot be performed.
The operating and maintenance instructions supplied with this engine must
be followed at all times. Flying any aircraft involves the risk of injury or death,
building and maintaining your own aircraft requires great personal
responsibility.

3.6. Information about fuels and lubricants
Fuel: Automobile fuel, unleaded premium
95 Octane (RON) minimums or
aviation gasoline 100LL.
Fuel pressure: 15 - 40 kPa
(0.15 - 0.4 kgf/cm2, 2.2 - 5.8 psi)
Oil type: No aircraft engine oils.
Only multi-grade brand-name 100% synthetic
oils for AUTOMOBILE engines, according to
API-classification (API min. SJ).
Take the viscosity of the oil as below table.
Oil volume: 4 Liters (4.2 quarts)
This will vary based on the oil line layout and oil cooler size used.
Oil level is between 1/2 and 2/3 of oil tank after 3 minutes idling.
Oil consumption: Max. 0.1 L/h (1/10th quart per hour)
Oil pressure: Min.490 kPa (5.0 kgf/cm2,71psi) @6200 r/min
Min.118 kPa (1.2 kgf/cm2,17 psi) @ idle r/min
Oil temperature (readings off of the feed line into engine):
Min. 50 Deg.C (122 Deg. F)
Max.120 Deg.C (248 Deg. F)
Optimum oil temperature range: 80 - 100 Deg.C (170 - 212 Deg.F)
CAUTION!
zDon't use any aircraft engine oils and additives.
zYou must install the oil cooler in the return line to the oil tank.
zFuel with more than 5% alcohol added must not be used.
