There is an ongoing debate about whether it’s better to drain gas or use a stabilizer since most gas now contains 10 percent ethanol, which can damage an engine’s fuel system. Although manufacturers often recommend emptying the fuel tank to winterize a lawn mower and other tools, some experts believe routinely emptying the fuel tank of some equipment can damage internal parts and possibly shorten the lifespan. Using fresh fuel and a quality fuel stabilizer before storage is an easy way to help ensure your equipment will be ready to run in the spring. However, it’s always best to consult the owner’s manual for the recommended practices based on the type of equipment.
