Quick Answer
Changing the oil in your generator before storing it is not strictly necessary, but it's a good idea to do so if you're storing it for an extended period, ideally 6 months or more. Fresh oil will help protect the engine and its components from corrosion and wear.
Why Change the Oil Before Storage
Changing the oil in your generator before storing it is a good preventive measure to protect the engine and its components from corrosion, wear, and degradation. Storing a dirty engine with old oil can lead to rust, corrosion, and damage to engine components, which may result in costly repairs when you’re ready to use the generator again. If you’re storing the generator for an extended period, ideally 6 months or more, it’s recommended to change the oil to ensure the engine is in good condition when you’re ready to use it.
How to Change the Oil in a Generator
Changing the oil in a generator is a relatively simple process. Start by locating the oil drain plug, usually at the bottom of the engine. Use a drain pan or a container to catch the old oil. Remove the oil drain plug and let the old oil drain completely. Once the old oil has drained, replace the oil drain plug and add the recommended type and amount of new oil. Be sure to dispose of the used oil responsibly and follow the manufacturer’s instructions for oil capacity and type.
Tips for Long-Term Generator Storage
In addition to changing the oil, it’s also essential to take other precautions when storing a generator for an extended period. Make sure the generator is completely fueled up and the fuel system is drained of any remaining fuel. This will help prevent fuel degradation and contamination. You should also check the air filter and replace it if necessary to ensure the engine is getting clean air. Finally, consider storing the generator in a dry, well-ventilated area, away from any flammable materials.
