5. How often should my lawn mower, tractor or snow blower be serviced?
Most manufacturers recommend servicing your equipment at least once a year. All small engines use petroleum-based products. As the additives in the petroleum break down and the oil and gas is left to settle over long periods of time, it can cause sludge and a gummy residue. This residue can cause engines to “hunt and surge” or, worse, break down. Also, the sludge can block key lubricating points resulting in rapid and excessive wear. Eventually, the engine could become completely ruined.
