GENERAL SERVICE INFORMATION

ENGINE OIL

Engine Oil Specifications

NOTICE: Only use the engine oil specified. Other
engine oils may affect warranty coverage, cause
internal engine components to seize or shorten
engine life. NEVER mix different types of engine oil.
This may adversely affect the lubricating properties
of the engine oil.
Use an engine oil that meets or exceeds the
following guidelines and classifications:
API Service Categories CD or higher
Recommended SAE Oil Viscosity: 10W30 or
15W40
Service Categories
• API Service Categories CD or higher
• ACEA Service Categories E-3, E-4 and E-5
• JASO Service Category DH-1
Definitions
• API Classification (American Petroleum Institute)
• ACEA Classification (Association des
Constructeurs Européens d'Automobilies)
• JASO (Japanese Automobile Standards
Organization)
NOTICE:
• Be sure the engine oil, engine oil storage
containers, and engine oil filling equipment are
free of sediment and water.
• Change the engine oil after the first 50 hours of
operation and then every 125 hours thereafter.
• Select the oil viscosity based on the ambient
temperature where the engine is being
operated. See the SAE Service Grade
Viscosity Chart (Figure 3-21).
• 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 shown in the SAE Service
Grade Viscosity Chart (Figure 3-21).
SAE 15W40 is the recommended oil viscosity.

(-20°C) (-10°C) (0°C) (10°C) (20°C) (30°C) (40°C)
Handling Oil
• When handling or storing oil, never allow dust and
water to contaminate the oil.
• Clean around the filler port before refilling.
• NEVER mix engine oils of different types or
brands. Mixing oil may cause the chemical
characteristics of the oil to change and lubricating
performance to decrease, reducing the engine's
life.
• Engine oil should be changed at the specified
intervals, regardless if the engine has been
operated
