Changing Engine Oil, Oil Filters and Bypass Oil Filter
To drain oil or change oil filters, wear gloves. Hot engine oil and parts may cause burns.
When changing engine oil, change the oil filters and bypass oil filter at the same time.
It is recommended to analyze engine oil properties at the same time.
Also change the oil filters whenever the filter alarm turns on.
The oil filters use paper elements. Never clean and reuse them. When replacing the filters, be sure to install
new packings.
Draining Engine Oil
To ensure thorough drainage, drain engine oil from the oil pan while it is still warm at 30 to 40 °C [86 to 104 °F]
after engine operation.
Be sure to suck out the engine oil when draining.
Changing Oil Filters (S12U)
Inspect the damage of the drain plug and filter bracket threaded sections, the center bolt and the gasket, if
any damage are found, replace it with the new one.
1 Clean the area around the oil filters.
2 Remove the center bolts and the gaskets, and
remove the cases and elements.
3 Remove the packing from the bracket.
Note: Disassemble the removed elemenets to see if

are metal particles on the elements, consult
your Mitsubishi dealer.

bracket surface and inside the groove of packing
that contacts the oil filter mounting sections.
