Engine Oil, Oil Filter and Bypass Oil Filter - Replace

Engine Oil - Drain

Drain engine oil from the drain port of oil pan after stopping the engine. 

Before draining engine oil, make sure the oil has cooled. 
When draining oil or replacing oil filters, be sure to wear gloves. You can get burned if you touch the hot engine oil 
or parts. 

Do not dump waste oil. It is forbidden by law. For disposal of waste oil, consult a dealer of Mitsubishi Heavy Indus-
tries, Ltd.
Engine oil, oil filter and bypass oil filter should be changed at the same time. 
Also engine oil analysis is recommended when changing engine oil. 
Do not reuse oil filter elements, as it is a paper type. When replacing filters, always replace gasket with new ones.
