Proper fueling of your gasoline-powered equipment can help it last longer, maximizing your investment.
If you purchase gasoline at the pump, check the labels to make sure it meets the requirements for your machine. Don't buy more than you can use in 30 days. Pump gasoline that's over 30 days old can lead to corrosion in outdoor power equipment engines. Ethanol in pump gasoline can be another concern. It burns hotter and can wear out small engines more quickly. Know the level of ethanol your equipment can safely use. High levels can damage a small engine, resulting in machinery that won't start. While you can find ethanol-free pump gasoline, most contains up to 10% ethanol.
Vent-free gas cans help reduce the buildup of moisture, which can damage engines.
Fuel stabilizer helps protect outdoor power equipment engines. You can find stabilizers designed to prevent the formation of corrosion, gum and varnish and to treat fuel for storage. There are also stabilizers designed to treat ethanol fuel blends.
Ethanol-free power equipment fuel is available for 4-cycle and 2-cycle engines. It stays fresh, doesn't degrade like pump gasoline and provides dependable starts. Pre-mixed fuel for 2-cycle engines also saves time. It's available in different gasoline-to-oil ratios so you don't need to measure and mix the fuel yourself.
If you don't use a machine frequently or if you're preparing it for storage in the off season, you need to protect the engine. Remove the fuel by draining it into an approved container or running the engine until the fuel system is dry. Keeping the tank and fuel system full of gasoline treated with a fuel stabilizer is an alternative for some models — just follow the instructions in your manual.
Fuel requirements and engine maintenance may vary from machine to machine. Follow the manufacturer's instructions for use, maintenance, fueling, safety and storage for your specific model.
