GASOLINE REQUIREMENTS
All gasoline is not the same. If a starting or performance problem is
encountered after new gasoline has been used, try another service
station or change brands.
Type of gasoline
to use
Always use gasoline that meets these requirements:
• Clean, fresh, unleaded gasoline.
• A minimun of 87 octane/87 AKI (91 RON). At altitudes over
5,000 feet, see "High-altitude use".
• Gasoline with up to 10% ethanol (gasohol) or up to 15%
MTBE (methyl tertiary butyl ether), is acceptable.
• Use of any gasoline other than those approved above will
void the engine warranty. Some areas require that fuel
pumps be marked if the gasoline contains alcohols or ethers.
If you are not sure if your gasoline contains alcohol or ethers
that are different than those approved above, then check with
the service station operator.
• Do not modify the engine fuel system or carburetor to run on
alternative fuels.
• Never mix oil with gasoline.
This engine is designed to operate on gasoline. The emission
control system for this engine is EM (Engine Modifications).

engine.
• Store gasoline in a clean, approved container and keep
the cap in place on the container.
CAUTION: Alcohol blended fuels (called gasohol or ethanol)
can attract moisture which leads to separation and formation
of acids during storage. Acidic gas can damage the fuel system
of an engine while in storage.
To prevent engine problems with the fuel system, empty the fuel
system before storage of 30 days or longer as follows.
1. Drain the fuel tank.
2. Start the engine. Let the engine run until the fuel lines and the
carburetor are empty.
3. After storage, make sure you use fresh fuel. See the storage
instructions for additional information.
4. Never use engine cleaner or carburetor cleaner in the fuel tank
or permanent damage can occur.
