CHECK AND MAINTENANCE
1. Daily check points
1.1 Checking engine oil level
IMPORTANT
• On diesel particulate filter (DPF) equipped
engines, part of the fuel may get mixed with
engine oil during the regenerating process.
This may dilute the oil and increase its quantity.
If the oil rises above the dipstick upper limit, it
means the oil has been diluted too much,
resulting in a trouble.
In such case, immediately change the oil for
new one.
• When you use an oil of different brand or
viscosity from the previous, drain the remaining
oil.
Do not mix 2 different types of oil.
NOTE
• When you check the engine oil level, make sure
that you put it in a level position.
If not, you cannot measure oil quantity
accurately.
• Make sure that you keep the oil level between
the upper and lower lines of the dipstick.
Too much oil can decrease the output or cause
too much blow-by gas.
On the closed breather type engine, the port
absorbs the mist and too much oil can cause oil
hammer.
But if the oil level is not sufficient, the moving
parts of engine can get a seizure.
