ENGINE OIL
The preferred engine oil is an equivalent of the American Petroleum
Institute API CI-4 15W-40.
The engine oil will need to be replaced at specified intervals due to oil
consumption, contamination of the oil as it flows through the engine,
and the breakdown of chemical additives. The recommended
frequency for changing the oil is approximately every 15,000 to 20,000
miles (24,000 to 32,000 km). Based on the driving conditions, quality of
fuel and environmental conditions the frequency may increase or
decrease based on the individual use of each motor coach.
Engine Oil level
CAUTION
Never operate the engine with oil level below the ADD mark or
above the FULL mark on the dipstick.
Oil dipstick and oil filler tube.
Place motor coach on level surface. Pull out dipstick and wipe it clean
with a clean cloth. Insert dipstick and pull out again. The oil level should
be between the ADD and the FULL marks on the dipstick.
If the oil level is too low, add oil through the oil filler tube. Bring level up
to FULL mark.
Engine Oil Viscosity
Since the viscosity of the engine oil changes with the temperature, the
average ambient temperature at the operating site of the engine is very
important for us to choose oil viscosity grade. Occasionally, if
temperature drops below the lower limit, it may reduce the cold staring
capability of the engine but not cause any damage to the engine.
The engine oil with an excessively high viscosity would cause engine
starting difficultly. Therefore, the ambient temperature while the engine
starts is the main basis on which to choose an engine oil. You may also
avoid replacement of the engine oil due to the temperature changes
provided the multi-functional engine oil is used.
NOTE: Adding any additive into above-mentioned engine is
unnecessary. Avoid mixing and using different types of engine oil.
Performing oil changes on time is crucial.
