Oil Recommendations
Using the proper type and weight of oil in the
crankcase is extremely important. So is checking oil
daily and changing oil regularly. Failure to use the
correct oil, or using dirty oil, causes premature engine
wear and failure.
Oil Type
Use high quality detergent oil of API (American
Petroleum Institute) service class SG, SH, SJ or higher.
Select the viscosity based on the air temperature at the
time of operation as shown in the following table.
Figure 1. Typical Courage
®
and Courage PRO
™
Series Vertical Shaft Engines.
NOTE: Synthetic oils meeting the listed classifications
may be used with oil changes performed at
the recommended intervals. However to allow
piston rings to properly seat, a new or rebuilt
engine should be operated for at least 50 hours
using standard petroleum based oil before
switching to synthetic oil.
A logo or symbol on oil containers identifies the API
service class and SAE viscosity grade. See Figure 3.
*Use of synthetic oil having 5W-20 or 5W-30 rating is acceptable,
up to 4°C (40°F).
**Synthetic oils will provide better starting in extreme cold below
23°C (-10°F).
Figure 2. Viscosity Grades Table.
NOTE: Using other than service class SG, SH, SJ or
higher oil or extending oil change intervals
longer than recommended can cause engine
damage.

Refer to Maintenance Instructions beginning on
page 7 for detailed oil check, oil change, and oil filter
change procedures.
Fuel Recommendations
WARNING: Explosive Fuel!
Gasoline is extremely flammable and its vapors can explode
if ignited. Store gasoline only in approved containers, in well
ventilated, unoccupied buildings, away from sparks or flames.
Do not fill the fuel tank while the engine is hot or running,
since spilled fuel could ignite if it comes in contact with hot
parts or sparks from ignition. Do not start the engine near
spilled fuel. Never use gasoline as a cleaning agent.
