L-N Operation Manual
2. Change the engine oil after the first 50 hours
of operation and then at every 200 hours
thereafter.
3. Select the oil viscosity based on the ambient
temperature where the engine is being
operated. See SAE Service Grade Viscosity
Chart
(Figure 2)
.
4. Yanmar does not recommend the use of
engine oil “additives.”
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-201-5.2-2
(HCI), ASTM D4739 (HCI)
Engine Oil Viscosity
Select the appropriate engine oil viscosity based
on the ambient temperature and use the SAE
Service Grade Viscosity Chart in
Figure 2
.
Figure 2
Checking Engine Oil
1. Make sure engine is level.
2. Remove oil cap / dipstick
(Figure 3, (1))
from
either location and wipe with clean cloth.
3. Fully reinsert oil cap / dipstick
but do not
screw in
.
4. Remove oil cap / dipstick. The oil level should
be between upper
(Figure 3, (2))
and lower
(Figure 3, (3))
lines on the oil cap / dipstick.
5. Fully reinsert oil cap / dipstick
(Figure 3, (1))
and hand tighten. Over-tightening the oil cap /
dipstick will damage it.

Adding Engine Oil
1. Make sure engine is level.
2. Remove oil cap / dipstick
(Figure 3, (1))
.
3. Add indicated amount of engine oil at either
one of the engine oil filler ports
(Figure 3, (4))
.
4. Wait one minute and check oil level.
5. Add more oil if necessary.
6. Fully reinsert oil cap / dipstick
(Figure 3, (1))
and hand tighten. Over-tightening the oil cap /
dipstick will damage it.
