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 0.5% is preferred.
Especially in the U.S.A. and Canada, Low Sulfur (300 to 500 ppm (mg/kg) or Ultra Low
Sulfur fuel should be used.
• NEVER mix kerosene, used engine oil or residual fuels with 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.
• Ash content must not exceed 0.01% by volume.
• Carbon residue content must not 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. (460μm) at HFRR test.
Fuel usage
The fuel with water or dust contaminated will cause the rough running of the engine. Be sure to use the clean
container for storing the fuel, meanwhile, the container must be stored at a clean and dry place. Then suck out the
upper level clean fuel with a pump as below figure.
The improper fuel cannot make the engine
Achieve the best performance, and even cause
the fault of the part.
Only use the upper level clean fuel. Do not
use the lower deposited fuel.
