FUEL AND OIL
GASOLINE
Suzuki highly recommends that you use alcohol-free unleaded gasoline whenever possible, with a minimum pump octane rating of 87 ((R+M)/2 method). In some areas, the only fuels that are available are oxygenated fuels. Oxygenated fuels which meet the minimum octane requirement and the requirements described below may be used in your outboard motor without jeopardizing the New Outboard Motor Limited Warranty.
Use of leaded gasoline can cause engine damage. Use of improper or poor quality fuel can affect performance and may damage your motor and fuel system.
Use only unleaded gasoline. Do not use fuel having lower than the recommended octane, or fuel that may be stale or contaminated by dirt/water etc.
Oxygenated fuels are fuels which contain oxygen-carrying additives such as alcohol.
Gasoline/Ethanol Blends
Blends of unleaded gasoline and ethanol (grain alcohol), also known as gasohol, may be used in your outboard motor if the ethanol content is not greater than 10%.
Fuel Pump Labeling
In some states, pumps that dispense oxygenated fuels are required to be labeled for the type and percentage of oxygenate, and whether important additives are present. Such labels may provide enough information for you to determine if a particular blend of fuel meets the requirements listed above. In other states, pumps may not be clearly labeled as to the content or type of oxygenate and additives. If you are not sure that the fuel you intend to use meets these requirements, check with the service station operator or the fuel suppliers.
• Be sure that any oxygenated fuel blend you use has octane ratings of at least 87 pump octane ((R+M)/2 method).
• If you are not satisfied with the drive ability or fuel economy of your outboard motor when you are using a gasoline/alcohol blend, you should switch back to unleaded gasoline containing no alcohol.
• If engine pinging is experienced, substitute another brand, as there are differences between brands.
Gasoline kept in the fuel tank for long periods of time will produce varnish and gum, which can damage the engine.
Always use fresh gasoline.
