DIESEL FUEL

DANGER
Diesel fuel is flammable and explosive under
certain conditions. See Safety on page 3.

Diesel Fuel Specifications

NOTICE
Only use diesel fuels recommended by Yanmar
Marine 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
No. 2-D, No. 1-D, ASTM D975
EN590:96
ISO 8217 DMX
BS 2869-A1 or A2
JIS K2204 Grade No. 2
■ Bio-Diesel Fuels
Yanmar approves the use of biodiesel fuels that do
not exceed a blend of 5 % non-mineral oil based
fuel with 95 % standard diesel fuel. Such biodiesel
fuels are known in the marketplace as B5 biodiesel
fuels. B5 biodiesel fuel can reduce particulate
matter and the emission of "greenhouse" gases
compared to standard diesel fuel.
CAUTION
If the B5 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.

B5 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 EN14214.
• In the United States, biodiesel fuels must comply
with the American Standard ASTM D-6751.
Biodiesel should be purchased only from
recognized and authorized diesel fuel suppliers.
Precautions and concerns regarding the use of
bio-fuels:
• 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.
• Even biodiesel fuels that comply with a suitable
standard as delivered, will require additional care
and attention to maintain the quality of the fuel in
the equipment or other fuel tanks. It is important
to maintain a supply of clean, fresh fuel. Regular
flushing of the fuel system, and/or fuel storage
containers, may be necessary.
• The use of biodiesel fuels that do not comply with
the standards as agreed to by the diesel engine
manufacturers and the diesel fuel injection
equipment manufacturers, or biodiesel fuels that
have degraded as per the precautions and
concerns above, may affect the warranty
coverage of your engine.
