Quick Answer
Using standard motor oil for generator storage is not recommended due to potential contamination and incompatibility issues with the engine's seals and fuel system.
Generator Storage Considerations
When it comes to storing a generator for an extended period, proper maintenance and protection of the engine and fuel system are crucial. Standard motor oil can be a potential contaminant in the fuel system, causing problems when the generator is restarted. Instead, use a high-quality, gasoline-specific storage stabilizer (such as Sta-Bil or Sea Foam) to prevent fuel breakdown and corrosion.
Choosing the Right Storage Stabilizer
When selecting a storage stabilizer, read the label carefully and ensure it is designed for gasoline engines. Some products may not be compatible with certain types of fuel or engine materials. Apply the recommended amount (usually 1-2 ounces per gallon of fuel) to the fuel tank, and mix well before storing the generator. This will help prevent fuel degradation, corrosion, and the formation of varnish and gum deposits.
Storing the Generator Properly
In addition to using a storage stabilizer, ensure the generator is stored in a well-ventilated area, away from direct sunlight and heat sources. Regularly check the fuel level and add stabilizer as needed to maintain a fresh supply of treated fuel. Also, consider storing the generator with the oil drained, as leaving oil in the engine can attract moisture and cause corrosion during storage.
