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:
  • Ultra Low Sulfur #2
  • #1 Diesel Fuel containing no more than 20% bio-diesel
For more information about recommended diesel fuels and the consequences of using bio-diesel fuel exceeding 20% bio- diesel, see Additional Technical Fuel Requirements below.
Diesel fuel should comply with the following world-wide specifications.
Diesel Fuel Specification Location

ASTM D975

No. 1D S15, S500

No. 2D S15, S500

 USA
EN590:96 European Union
ISO 8217 DMX International

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, Ultra Low Sulfur fuel should be used.
  • Bio-Diesel fuels.
  • 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. 460μm (0.018 in.) 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.
These B20 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 ASTMD-6751.2.
  2. Bio-fuels should be purchased only from recognized and authorized diesel fuel suppliers.
Precautions and concerns regarding the use of bio-fuels:
  1. Free methanol in FAME may result in corrosion of aluminum and zinc FIE components.
  2. Free water in FAME may result in plugging of fuel filters and increased bacterial growth.
  3. High viscosity at low temperatures may result in fuel delivery problems, injection pump seizures and poor injection nozzle spray atomization.
  4. FAME may have adverse effects on some elastomers (seal materials) and may result in fuel leakage and dilution of the engine lubricating oil.
  5. Even bio-diesel 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.
  6. The use of bio-diesel fuels that do not comply with the standards as agreed to by the diesel engine manufacturers and the diesel fuel injection equipment manufacturers, or bio-diesel fuels that have degraded as per the precautions and concerns above, may affect the warranty coverage of your engine.
B21 To B100 Bio-diesel Fuel Blend Usage
B21 to B100 bio-diesel is not approved for this POLARIS application.
Approved Engines
Only the Kubota engine series listed below may operate with bio-diesel fuel concentrations up to B20 for POLARIS applications.
NOTICE
Do not exceed bio-diesel fuel blend B20 for this POLARIS application.
  • Kubota 902D
Approved Fuel
NOTICE
Raw pressed vegetable oils are not considered bio-diesel, and are unacceptable for use as fuel in any concentration in Kubota engines.
Bio-diesel fuel blends up to B20 must comply with the following standards:
  • EN14214 (European standard) and/or ASTM D-6751 (American standard).
  • All applicable engines may operate with bio-diesel fuel up to a maximum B20 (20% bio- diesel blend) concentration.
Operating Conditions with B20 Bio-diesel Fuel Blends
Engine Warranty
Damages, performance or service concerns determined to be caused by the use of bio-diesel fuel not meeting the specifications outlined above are not considered to be defects in material or factory workmanship and are not covered under warranty. The same applies to damages or other concerns induced by not complying with the recommended operating conditions of Kubota engines with bio-diesel fuel.

Handling Fuel

WARNING
Diesel fuel is flammable and explosive under certain conditions.
  • NEVER refuel with the engine running.
  • Always refuel outdoors or in a well ventilated area.
  • Fill the fuel tank with diesel fuel ONLY. Filling the fuel tank with gasoline may result in a fire and will damage the engine.
  • Remove flammable material containers from the box before filling them with fuel.
  • Do not smoke or allow open flames or sparks in or near the area where refueling is performed or where fuel is stored.
  • Wipe up all spills immediately.
  • Keep sparks, open flames or any other form of ignition (match, cigarette, static electricity source) well away when refueling.
  • NEVER remove the fuel cap while the engine is running.
  • NEVER overfill the fuel tank. Do not fill the tank neck.
  • If fuel spills on your skin or clothing, immediately wash it off with soap and water and change clothing.

Refueling

The fuel tank filler cap is located on the left side of the vehicle near the driver’s seat. Remove the cap and add the recommended fuel to the bottom of the filler neck. Do not overfill.

Cold Weather Operation

Cold weather operation can result in fuel gelling if the incorrect fuel type is used. Use the following fuel blending guideline to prevent this from occurring.

Bio-Diesel Blended Fuel

NOTICE
Never use bio-diesel blended fuel containing more than 20% bio-diesel in this vehicle.
Bio-diesel blended fuel has unique qualities that should be considered before using it in this vehicle:
  • Cold weather conditions can lead to plugged fuel system components and hard starting.
  • Bio-diesel blended fuel is an excellent medium for microbial growth and contamination which can cause corrosion and plugging of fuel system components.
  • Use of bio-diesel blended fuel may result in premature failure of fuel system components, such as plugged fuel filters and deteriorated fuel lines.
  • Shorter maintenance intervals may be required, such as cleaning the fuel system and replacing fuel filters and fuel lines.
  • Using bio-diesel blended fuels containing more than 20% bio-diesel can affect engine life and cause deterioration of hoses, tubes, injectors, injector pump and seals.
Use the following guidelines if bio-diesel blended fuel is used:
  • Never use bio-diesel blended fuel containing more than 20% bio-diesel in this vehicle.
  • Ensure the fuel tank is as full as possible at all times to prevent moisture from collecting in the fuel tank.
  • Ensure that the fuel tank cap is securely tightened.
  • Clean up any spilled fuel immediately to prevent damage to painted surfaces.
  • Drain all water from the fuel filter daily before operating the vehicle.
  • Do not exceed the engine oil change interval. Extended intervals can result in engine damage.
  • Before vehicle storage, drain the fuel tank, refill with 100% petroleum diesel fuel, add fuel stabilizer and run the engine for at least 30 minutes.
NOTICE
Bio-diesel blended fuel does not have long term stability and should not be stored for more than three months.
