Engine Oil

LUBRICATION

3. Engine Oil

A: INSPECTION

CAUTION:
If the engine oil is spilt over exhaust pipe or the
under cover, wipe it off with cloth to avoid emit-
ting smoke or causing a fire.
1) Park the vehicle on a level surface.
2) Remove the oil level gauge and wipe away the
oil.
3) Reinsert the oil level gauge all the way. Be sure
that the oil level gauge is correctly inserted and
properly orientated.
4) Pull out the oil level gauge again, and check the
oil level. If the engine oil level is below “L” line,
check for oil leakage from engine and add oil to
bring the level up to the “F” line.
5) Start the engine and warm it up for a time.
6) After turning off the engine, wait a few minutes
for the oil to return to the oil pan before checking
the level.

NOTE:
• Just after driving or while the engine is warm, en-
gine oil level shows in the range between “F” line
and cutout portion. This is caused by thermal ex-
pansion of engine oil.
• To prevent overfilling of engine oil, do not add oil
above “F” line when the engine is cold.
• As the oil level gauge is used for daily mainte-
nance, “F” line and “L” line is set assuming that the
engine is cold.

CAUTION:
If the engine oil is spilt over exhaust pipe or the
under cover, wipe it off with cloth to avoid emis-
sion of smoke or causing a fire.
1) Set the vehicle on a lift.
2) Open the engine oil filler cap for quick draining of
engine oil.
3) Lift up the vehicle.
4) Drain engine oil by loosening the engine oil drain
plug.

NOTE:
Prepare the container for draining of engine oil.

5) Tighten the engine oil drain plug after draining
engine oil.

NOTE:
Use a new drain plug gasket.

Tightening torque:

44 N·m (4.5 kgf-m, 32.5 ft-lb)

6) Lower the vehicle.
7) Using engine oil of proper quality and viscosity,
fill engine oil through the oil filler duct to the “F” line
on the level gauge. Make sure that the vehicle is
parked on a level surface when checking oil level.

Recommended oil:

Refer to “SPECIFICATION” for the recom-
mended oil. <Ref. to LU(H4SO)-2, SPECIFI-
CATION, General Description.>

Engine oil capacity:

Refer to “SPECIFICATION” for the engine oil
capacity. <Ref. to LU(H4SO)-2, SPECIFICA-
TION, General Description.>

8) Close the engine oil filler cap.
9) Start the engine, and spreads the oil in engine
room.
10) After stopping the engine, recheck the oil level.
If necessary, add engine oil up to the “F” line on oil
level gauge.
