Should power equipment equipped with 4 cycle OHV motors have the gas drained for winter storage? On 2 cycle equipment, I know the gas should be run out to prevent gumming. However, I am getting conflicting reports on 4 cycle motors. Some people say leave the tank 1/4 full and add a fuel stabilizer. The gas is supposed to help the tank from rusting. Other people say to drain the whole thing. Who's right?
