The oil should not be dirty and should have
appropriate viscosity. No coolant or diesel fuel
should be present. The level should be between
the upper

and lower limit lines
(Figure 4-1, (5))
on the dipstick.

2. If oil level is low, fill to the specified level through
the filler port.
NOTICE: Avoid overfilling the
engine oil. Add oil to the upper limit line on the
dipstick. Overfilling may induce oil into the
combustion chamber and damage components.
