constitute a complete aircraft’s operator’s
instructions, and applies to the engine only.
Refer to the airframe manufacturer's instruction
for additional information.
2. ENGINE OPERATION AND LIMITS
Data for the following limits may be found in the
Model Specification Data in the appropriate
Appendices. These Engine Operational Limits
should be reviewed by the operator prior to any
initial operations of the O-360 or IO-360 Engine
Series.
A. Propeller Load and Full Throttle Curve
B. Altitude Performance at Best Power
C. Cruise Performance Maps
D. Fuel Mixture Curves
E. Minimum Oil Quantity
F. Fuel Pressure and Flow Requirements
G. Fuel Grade Requirements
H. Oil Pressure and Temperature Limits
I. Operating Conditions
J. Accessory Temperature Limits
3. OPERATION INSTRUCTIONS
Note: The Vantage series engines have been
carefully run-in by Superior Air Parts, but
requires further break-in until oil consumption
has stabilized. After this period, a change to
approved ashless dispersant oil should be
made. Refer to the Special Procedures
Chapter Five, Break-in Instructions.
Superior Vantage Engines are certified for
100LL Avgas per ASTM D910, 91/98 (lead
optional) Avgas per ASTM D910 and Motor
Gasoline with a minimum antiknock index
(R+M/2 method) of 91 per ASTM D4814.
The Vantage series engine can operate and
perform at a rated power using auto fuel of
at least 91 Octane (R+M/2), without alcohol.
The higher the octane the greater the
detonation margin during high power and/or hot
operation. When operating on unleaded fuel,
Superior Air Parts recommends using fresh
premium, 91 minimum Octane, auto fuel
available at major brand stations.
Due to the higher vapor pressure of auto fuel,
carburetor icing and vapor lock are more likely.
The use of motor gasoline is prohibited with
fuel temperatures over 85
°
F altitudes at 12,500
feet MSL and over 110
°
F at Sea Level.
The following states require compliance with D-
4814, or require critical specified values per
ASTM D-4814:
