Diesel Fuel Specifications

WARNING
Fire and Explosion Hazard.
Diesel fuel is flammable and explosive
under certain conditions.
Only use diesel fuels recommended by
Yanmar for the best engine performance,
to prevent engine damage and to comply
with EPA warranty requirements. Only use
clean diesel fuel.
Diesel fuel should comply with the
following specifications. The table lists
several worldwide specifications for diesel
fuels.
DIESEL FUEL
SPECIFICATION
ASTM D975 No. 2-D S15,
No. 1-D S15
EN590-2009
ISO 8217 DMX
BS 2869-A1 or A2
JIS K2204 Grade No. 2
Biodiesel Fuels
Yanmar approves the use of biodiesel
fuels that do not exceed a blend of 7%
non-mineral oil based fuel with 93%
standard diesel fuel. Such biodiesel fuels
are known in the marketplace as B7
biodiesel fuels. B7 biodiesel fuel can
reduce particulate matter and the emission
of "greenhouse" gases compared to
standard diesel fuel.
If the B7 biodiesel fuel used does not meet
the approved specifications, it will cause
abnormal wear of injectors, reduce the life
of the engine and it may affect the warranty
coverage of your engine.

B7 diesel fuels must meet certain
specifications.
The biodiesel fuels must meet the
minimum specifications for the country in
which they are used:
• In Europe, biodiesel fuels must comply
with the European Standard
EN590-2009, EN14214.
• In the United States, biodiesel fuels must
comply with the American Standard
ASTM D-6751 Grade-S15, D7467 Grade
B7-S15.
Biodiesel should be purchased only from
recognized and authorized diesel fuel
suppliers.
Precautions and concerns regarding
the use of biofuels:
• Biodiesel fuels have a higher content of
methyl-esters, which may deteriorate
certain metal, rubber and plastic
components of the fuel system. The
customer and / or boat builder are
responsible to verify the usage of
biodiesel compatible components on the
vessel fuel supply and return systems.
• Free water in biodiesel may result in
plugging of fuel filters and increased
bacterial growth.
• High viscosity at low temperatures may
result in fuel delivery problems, injection
pump seizures and poor injection nozzle
spray atomization.
• Biodiesel may have adverse effects on
some elastomers (seal materials) and
may result in fuel leakage and dilution of
the engine lubricating oil.
