Additional Technical Engine Oil
Requirements:
The engine oil must be changed when the
Total Base Number (TBN) has been
reduced to 2.0. TBN (mgKOH/g) test
method; JIS K-2501-5.2-2 (HCI), ASTM
D4739 (HCI).
Engine Oil Viscosity
SAE 15W40 is the recommended oil
viscosity.
Checking Engine Oil
1. Make sure engine is level.
2. Remove dipstick (Figure 4, (3)) and
wipe with clean cloth.
3. Fully reinsert dipstick.
4. Remove dipstick. The oil level should be
between upper (Figure 4, (4)) and lower
(Figure 4, (5)) lines on the dipstick.

Adding Engine Oil
1. NOTICE: Prevent dirt and debris from
contaminating engine oil. Carefully clean
the dipstick, filler port cap and the
surrounding area before you remove the
cap. Remove the yellow oil filler port cap
(Figure 4, (2)) at the top of the rocker
arm cover (Figure 4, (1)) and fill with
engine oil.
2. Fill with engine oil to the upper limit
(Figure 4, (4)) on the dipstick
(Figure 4, (3)). Insert the dipstick fully to
check the level. NOTICE: NEVER overfill
the engine with engine oil.
Engine Lube Oil Capacity (at rake 0
deg.)
Full: 18.8 L (19.9 quarts)
Effective: 8 L (8.5 quarts)
• “Full” means the oil amount at the upper
limit (Figure 4, (4)) on a dipstick.
• “Effective” means the difference
between oil amount at upper limit and
that at lower limit (Figure 4, (5)).
NOTICE: ALWAYS keep the oil level
between the upper and lower lines on the
oil cap / dipstick.
3. Hand-tighten the filler port
(Figure 4, (2)) cap securely.
