Engine Oil Maintenance
Checking the Engine Oil Level
1) Maintain Proper Oil Level
Between “ADD”(Y) and “Full” (X)
on
the oil level Gauge. DO NOT fill
above “Full” mark as catastrophic
engine damage will occur.
2) Remove the oil filler cap and add oil if necessary. Clean the oil filler cap
with a clean rag or towel. Reinstall the oil filler cap by hand.
Lubricating Oil Specifications
Use only good quality Lubricating Oil, which meets the following Specifications.
API Class
CJ-4
Engine Oil
LUBRICATING OIL VISCOSITY
RECOMMENDATIONS
The minimum ambient temperature during cold engine start-up and the maximum ambient temperature
during engine operation determine the proper SAE viscosity grade of oil.
Refer to the Engine Oil Viscosity Table below (Lowest Ambient Temperature) in order to determine the
required oil viscosity for starting an engine in cold conditions.
Refer to the Engine Oil Viscosity Table below in order to select the oil viscosity for engine operation at the
ambient temperature range that is anticipated.
Ambient Temperature Range
Above 25 C (77° F)
SAE 10W-30 or 15W-40
-10°C to 25°C (14° to 77° F)
SAE 10w-30 or 15W-40
Below -10° C (14°F)
SAE 10W-30
