LUBRICATION SYSTEM
GENERAL INFORMATION
Engine oil lubricates, cools, seals, prevents corrosion,
and cleans engines, enhancing engine performance and
extending the engine's lifetime. If a vehicle is
continuously driven while engine oil is insufficient, the
moving parts of the engine may get stuck, causing
engine faults.
Engine oil should be checked through the oil level gauge
and replenished if required. Oil level should be checked
while the engine is stopped. To check the oil level, turn off
the engine while it is running and wait for 5 ~10 minutes
to allow the engine oil to flow back into the oil pan. The
engine oil level should indicate between the upper limit
and the lower limit of the oil level gauge.
Engine oil should be periodically replaced based on the
regular inspection table and the oil filter and the cartridge
should be replaced as the engine oil is replaced.
ENGINE OIL STANDARDS
Use the specified engine oil suitable for the environment
and conditions of the site where the engine will be used.
Use the engine oil which satisfies the following recommended specifications.
NOTE:
Use of Doosan genuine engine oil is recommended.
