1.3.2 Lubricating oil

IMPORTANT:
Only use the recommended engine oil to keep the durability of the engine.
(1) Selection of lube oil
Engine oil shoud comply with the following specifications.
1)Classification
• API classification
• ACEA classification
• JASO classification
The 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)
DO NOT use The following engine oils.
• API : CG-4 , CH-4
• ACEA : E-1, E-2 , B grade
• JASO : DH-2 , DL-1
Reason
API CG-4, CH-4
In case CG-4, CH-4 is to be used for YANMAR TNV diesel engine series, there is a possibility that
excessive wears occur on the valve train system due to the content of oil.
ACEA E-1,E-2, B
These fuels are developed for the different type of diesel engines.
JASO DH-2, DL-1
These fuels are developed for the different type of diesel engines.
2)Viscosity
Selection of viscosity will be determined depending
on the ambient temperature.
(Refer to the chart on the right.)
The following requirements are also need to be
fulfilled.
• Standard engine oil service interval is 250 hrs or
every 12 months.
• DO NOT add any additives to the engine oil.
• DO NOT mix the different types (brand) of engine
oil.
• DO NOT use synthetic oil.
