Bio-Diesel Blended Fuel
Use the following guidelines if bio-diesel blended fuel is used:
• Never use bio-diesel blended fuel containing more than 5% 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 dam-
age.
• 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.
