Fuel Recommendations
NOTICE: For the best engine performance, to prevent engine damage and to comply with EPA/CARB
warranty requirements, use ONLY the recommended diesel fuels. Use only CLEAN diesel
fuel.
POLARIS recommends the following diesel fuels for use in this vehicle:
•Low Sulfur
• Ultra Low Sulfur #2
• #1 Diesel Fuel containing no more than 5% bio-diesel (see page 33)
See page 35 for cold weather fuel blend recommendations. For more information about rec-
ommended diesel fuels and the consequences of using bio-diesel fuel exceeding 5% bio-die-
sel, see Additional Technical Fuel Requirements below.
Diesel fuel should comply with the following world-wide specifications.
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. Espe-
cially in the U.S.A. and Canada, Low Sulfur (300 to 500 ppm (mg/kg) or Ultra Low Sulfur
fuel should be used.
• Bio-Diesel fuels: see pages 33-34.
• 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 perfor-
mance.
• 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.
