Nonvehicle Motor Oils

Other kinds of motors, such as internal combustion engines in motorcycles, mopeds, outboard motors for boats, snowmobile, ATVs, personal watercraft, scooters, and gocarts, etc., also use motor oil, as well as engines that are not in vehicles such as those for electrical generators. Examples include 4stroke or 4cycle internal combustion engines such as those used in many lawn mowers and other engines, and special 2cycle oil used in 2stroke or 2cycle internal combustion engines such as those used in various smaller engines like snow throwers blowers, chain saws, toy engines like those in model airplanes, certain gardening equipment like weed/grass trimmers, leaf blowers, soil cultivators, etc.
Often, the applications are not exposed to as wide a temperature range in use as vehicles, so these oils may be single grade or have less viscosity index improver. 2cycle oil is used differently than other motor oils in that it is premixed with the gasoline or fuel, often in a gasoline oil ratio of 50 1, and burned in use along with the gasoline.In addition to the 2cycle oil used if they have gasoline engines, chain saws also separately use bar and chain oil for lubricating the surfaces where the cutting chain moves around bar. Other examples of mechanical equipment often using oil include oildriven compressors, vacuum pumps, diffusion pumps, sewing machines and other devices with motors, oildriven hydraulic equipment, turbines, and mechanisms using gears such as gear differentials for rear wheeldrive vehicles. The oil properties will vary according to the needs of these devices.
