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.
Draining engine oil
To ensure thorough drainage, drain engine oil while it is still warm after engine operation.
Note: Do not suck out the engine oil when draining.
Changing oil filters and bypass oil filter
1 Clean the area around the oil filters.
2 Place an oil-receiving tray under the oil filters.
3 Using the provided filter wrench, remove each
oil filter.
Note: Check the filter elements in the removed oil
filter for metal particles. If metal particles are
found, consult a Mitsubishi dealer. Also
change the oil filters whenever the filter alarm
turns on.
4 Wipe oil from the oil filter mounting surface on
the filter alarm bracket with a cloth.
5 Check the new oil filter for proper seating of the
gaskets.
6 Apply clean engine oil to the gaskets on the new
oil filter.
7 Install the oil filter. When the gasket contacts the
mounting surface on the filter bracket, further
rotate 3/4 to a full turn.
Do not use the filter wrench for the installation of oil
filters.
Do not dent or scratch the oil filter cartridge sur-
faces.
