0B-8 MAINTENANCE AND LUBRICATION
6) Replenish oil until oil level is brought to FULL level mark on
dipstick. (oil pan and oil filter capacity). The filler inlet is at
the top of the cylinder head cover.
It is recommended to use engine oil of SE, SF, SG, SH or SJ
grade.
NOTE:
Select the appropriate oil viscosity according to the proper
engine oil viscosity chart [A].
Engine oil specification :
7) Check oil filter and drain plug for oil leakage.
8) Start engine and run it for 3 minutes. Stop it and wait 5 min-
utes before checking oil level. Add oil, as necessary, to bring
oil level to FULL level mark on dipstick.
[A]: Proper engine oil viscosity chart
H27 engine
Oil pan capacity liters (US/lmp pt.) About 5.0 (10.6/8.8)
Oil filter capacity liters (US/lmp pt.) About 0.5 (1.1/0.9)
Others liters (US/lmp pt.) About 0.7 (1.5/1.2)
Total liters (US/lmp pt.) About 6.2 (13.1/10.9)
NOTE:
Engine oil capacity is specified. However, note that the
amount of oil required when actually changing oil may
somewhat differ from the data in the table depending on
various conditions (temperature, viscosity, etc.)
1. Full level mark (hole)
2. Low level mark (hole)

Precaution for Maintenance Service
•When having driven through water, check immediately if
water has entered (if so, oil is cloudy). Water mixed oil must
be changed at once.
•Whenever vehicle is hoisted for any other service work than
oil change, also be sure to check for oil leakage and status of
breather hoses.
Differential Gear Oil Change
1) Before oil change or inspection, be sure to stop engine and
lift up vehicle horizontally.
2) Check oil level and existence of leakage. If leakage is found,
correct its cause.
3) Drain old oil and pour proper amount of gear oil as specified
(roughly up to level hole).
4) Torque drain plug (3) and level/filler plugs (2) to specification.
“A” : Sealant 99000-31110
Tightening torque
Differential oil level/filler plug (a) :
50 N·m (5.0 kg-m, 36.5 lb-ft)
Differential oil drain plug (b) :
28 N·m (2.8 kg-m, 20.5 lb-ft)
Hypoid gear oil :
API GL-5, SAE 75W-85, 80W-90 or 90
Oil capacity :
2.5 liters (5.3/4.4 US/Imp. pt.) NOTE:
Hypoid gear oil must be used for differential.
It is highly recommended to use SAE 80W-90 viscosity.
