For gas-powered snow blowers like the Briggs & Stratton 208cc, maintenance is typical of small 4-stroke, air-cooled devices. Little more than adding gas and making sure the oil is clean and at the correct level should be necessary. Corded electric snowblowers like the Greenworks (our top pick) are advertised as maintenance-free. For improved performance, some suggest spraying the snowblower chute and auger blades with WD-40 or another spray-on lubricant.
