DIESEL FUEL
Diesel Fuel Specifications
Diesel fuel should comply with the following
specifications. The table lists several worldwide
specifications for diesel fuels.
Additional Technical Fuel Requirements
• The fuel cetane number should be equal to 45 or
higher.
• The sulfur content must not exceed 0.5% by
volume. Less than 0.05% is preferred.
• Bio-Diesel fuels.
page 31
• NEVER mix kerosene, used engine oil, or
residual fuels with the diesel fuel.
• Water and sediment in the fuel should not exceed
0.05% by volume.
• Keep the fuel tank and fuel-handling equipment
clean at all times.
• Poor quality fuel can reduce engine performance
and / or cause engine damage.
• Fuel additives are not recommended. Some fuel
additives may cause poor engine performance.
Consult your Yanmar representative for more
information.
• Ash content not to exceed 0.01% by volume.
• Carbon residue content not to exceed 0.35% by
volume. Less than 0.1% is preferred.
• Total aromatics content should not exceed 35%
by volume. Less than 30% is preferred.
• PAH (polycyclic aromatic hydrocarbons) content
should be below 10% by volume.
• Metal content of Na, Mg, Si, and Al should be
equal to or lower than 1 mass ppm. (Test analysis
method JPI-5S-44-95)
• Lubricity: Wear mark of WS1.4 should be Max.

Bio-Diesel Fuels
In Europe and in the United States, as well as some
other countries, non-mineral oil based fuel
resources such as RME (Rapeseed Methyl Ester)
and SOME (Soybean Methyl Ester), collectively
known as FAME (Fatty Acid Methyl Esters), are
being used as extenders for mineral oil derived
diesel fuels.
Yanmar approves the use of bio-diesel fuels that do
not exceed a blend of 5% (by volume) of FAME with
95% (by volume) of approved mineral oil derived
diesel fuel. Such bio-diesel fuels are known in the
marketplace as B5 diesel fuels.
These B5 diesel fuels must meet certain
requirements.
1. The bio-fuels must meet the minimum
specifications for the country in which they are
used.
• In Europe, bio-diesel fuels must comply with
the European Standard EN14214.
• In the United States, bio-diesel fuels must
comply with the American Standard ASTM D-
6751.
2. Bio-fuels should be purchased only from
recognized and authorized diesel fuel suppliers.
