OIL AND FUEL INFORMATION

OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use fresh, clean
unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.
DEFINITION OF BLENDED FUELS
WARNING:
It has been proven that fuel containing greater than 10% ethanol will likely damage this engine
and void the warranty.
Today's fuels are often a blend of gasoline and oxygenates such as ethanol, methanol, or MTBE (ether). Alcohol-
blended fuel absorbs water. As little as 1% water in the fuel can make fuel and oil separate. It forms acids when
stored. When using alcohol-blended fuel, use fresh fuel (less than 30 days old).
USING BLENDED FUELS
If choosing to use a blended fuel, or its use is unavoidable, follow recommended precautions:
• Always use the fresh fuel mix explained in the operator's manual
• Use the fuel additive STA-BIL® or an equivalent
