be hot.

Oil pressure check should be done in“Neutral position”.
1. Check oil level.
2. Remove oil pressure switch.
3. Install pressure gauge.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load.

SAE Viscosity Number

For warm and cold areas: 10W-30 is suit-
able. The use of 5W-30 can have a positive
effect on fuel economy (ACEA A1-98).

For hot areas: 20W-40 and 20W-50 are suit-
able.

For cold and warm areas: 10W-30 is prefer-
able for ambient temperatures above20°C
(4°F).

On turbocharger models, 5W-20 is not
recommended, and 5W-30 should be used
only below 0°C (32°F).

For hot areas: 20W-40 and 20W-50 are suit-
able.

Changing Engine Oil
WARNING:

Be careful not to burn yourself, as the engine oil is hot.

Prolonged and repeated contact with used engine oil
may cause skin cancer; try to avoid direct skin contact
with used oil. If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Stop engine.
3. Remove drain plug and oil filler cap.
4. Drain oil and refill with new engine oil.
Oil grade: API SH or SJ/ACEA A2/96

RICANTS”, MA-16.

CAUTION:

Be sure to clean drain plug and install with new washer.
Drain plug:
:29-39N·m (3.0 - 4.0 kg-m, 22 - 29 ft-lb)

The refill oil capacity depends on oil temperature and
drain time. Use these specifications as a reference only.
Always use the dipstick to determine when the proper
amount of oil is in the engine.
5. Start engine and check area around drain plug and oil filter
for oil leakage.
6. Run engine for a few minutes, then turn it off. After several
minutes, check oil level.
Changing Engine Oil Filter
1. Remove oil filter with Tool.
WARNING:
Be careful not to burn yourself, as the engine and the engine
oil are hot.
2. Clean the oil filter mounting surface on the cylinder block.
Coat the rubber seal of the new oil filter with engine oil.

3. Screw in the oil filter until a slight resistance is felt, then
tighten an additional 2/3 turn.
4. Add engine oil.
Refer to“Changing Engine Oil”, MA-24.

Clean excess oil from engine.
Checking and Changing Spark Plugs
1. Remove ignition coils.
2. Remove spark plugs with spark plug wrench.
3. Check insulator for cracks or chips, gasket for damage or
deterioration and electrode for wear and burning. If exces-
sively worn, replace with new spark plugs.
Spark plug:
Make CHAMPION NGK
Standard type RC10YCC4, RC10YC4 BKR5E-11
Hot type RC12YCC4, RC12YC4 BKR4E-11
Cold type RC7YCC4, RC7YC4 BKR6E-11
Use standard type spark plug for normal condition.
The hot type spark plug is suitable when fouling may occur with
the standard type spark plug such as:

frequent engine starts

low ambient temperatures
The cold type spark plug is suitable when spark knock may occur
with the standard type spark plug such as:

extended highway driving

frequent high engine revolution
4. Check spark plug gap.
Gap: 1.0 - 1.1 mm (0.039 - 0.043 in)
5. Install spark plugs. Reinstall ignition coils.
