Number 1 Ultra Low Sulfur Diesel Fuel results in a
noticeable decrease in fuel economy.
• Climatized Ultra Low Sulfur Diesel Fuel is a blend of
Number 2 Ultra Low Sulfur and Number 1 Ultra Low

which wax crystals form in fuel.
• The fuel grade should be clearly marked on the pump
at the fuel station.

engine and exhaust system damage. Refer to “Fuel
