Engine Oil Specifications
Use an engine oil that meets or exceeds
the following guidelines and classifications:
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)
Notes:
1. Be sure the engine oil, engine oil
storage containers, and engine oil
filling equipment are free of
sediments and water.
2. Change the engine oil after the first
50 hours of operation and then at
every 250 hours thereafter.
3. Select the oil viscosity based on the
ambient temperature where the
engine is being operated. See the
SAE Service Grade Viscosity Chart
(Figure 3) .
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 shown
in the SAE Service Grade Viscosity Chart
in
(Figure 3) .
SAE15W40 is the recommended oil
viscosity.
