Owning a generator is a smart way to ensure a reliable power source during emergencies or when off-grid power is needed. However, just like any other engine-powered equipment, proper maintenance is key to extending the lifespan of a generator and ensuring it runs efficiently when you need it most. One of the often overlooked aspects of generator maintenance is fuel stabilizers.
Fuel stabilizers are essential for preventing fuel from degrading and causing engine performance issues over time. When fuel sits in the tank for an extended period, especially in seasonal or standby generators, it can break down and form gum and varnish deposits that clog fuel lines, carburetors, and other components. This is where fuel stabilizers come in, as they help preserve the integrity of fuel and keep your engine running smoothly.
