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.
