Oil could be called the lifeblood of small engines such as those found in pressure washers, lawnmowers, snowblowers, wood chippers, generators, and more. You must be sure that an engine has not only enough oil to operate effectively, but that the oil is changed on a regular basis, and that may mean once or more per year. It has to be done with the right oil, as well as the ideal filters to keep the machine in tip-top condition. Regular motor oil is not a good fit for many lawn care machines, and it is best to choose small engine oil, such as SAE 30, that is specifically formulated for 4-cycle and air-cooled engines so commonly found in yard and garden machinery. It is also important to remember that you should never overfill the machine with oil, as too much will harm the engine. This 18 oz. bottle of 4-cycle oil is ideal for brands like Briggs & Stratton, Craftsman, Husqvarna, Toro, Troy-Bilt, Simplicity, Wheel Horse, Snapper, and Lawn-Boy, among others. It is a good idea to have the appropriate parts for a full oil change, including filters when performing this vital maintenance.
