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.

Especially in U.S.A. and Canada, Low Sulfur

(300-500mg/kg sulfur content) or Ultra Low

Sulfur fuel should be used.

• Bio-Diesel fuels. See Bio-Diesel Fuels on

page 4-9.

• 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.

0.018 in. (460 µm) at HFRR test.

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.
