On the other hand, conventional oil is derived from petroleum and is less expensive. It provides good engine protection but may not perform as well in extreme temperatures.
Detergent Oil and Non-Detergent Oil
Another distinction in lawn mower oils is between detergent and non-detergent types. Detergent oil contains additives that help clean the engine by dispersing contaminants and preventing the formation of sludge and varnish. This type of oil is recommended for most modern engines. Non-detergent oil, lacking these additives, is less common and typically used in older engines or those specified by the manufacturer.
Viscosity and Temperature Considerations
Viscosity is a critical factor when selecting lawn mower oil. The Society of Automotive Engineers (SAE) assigns viscosity ratings to oils based on their flowability in cold and hot temperatures. A lower viscosity number indicates thinner oil that flows more easily in cold temperatures, making it ideal for starting engines in winter. However, it may not provide sufficient lubrication in very hot conditions. Conversely, a higher viscosity number indicates thicker oil that offers better lubrication in hot temperatures but may be difficult to start the engine with in cold conditions.
Single-Viscosity and Multi-Viscosity Oils
Single-Viscosity Oils
Single-viscosity oils have a single viscosity rating and are designed to perform well within a specific temperature range. For example, SAE 30 oil is suitable for warm temperatures and provides good engine protection during the operating season.
Multi-Viscosity Oils
Multi-viscosity oils, such as 10W-30, have a wider range of viscosity, making them adaptable to more extreme temperature variations. The “W” in multi-viscosity oil designations stands for winter, indicating the oil’s performance in cold temperatures. Multi-viscosity oils are convenient as they can be used year-round without needing to change the oil type with the seasons.
Environmental and Health Considerations
When choosing the best oil for your push lawn mower, it’s also important to consider the environmental and health implications. Biodegradable oils and ecological oils are designed to be more environmentally friendly, breaking down naturally in the environment and reducing the risk of contamination. However, these oils may be more expensive and not as widely available as conventional oils.
Disposal Considerations
Regardless of the oil type chosen, proper disposal is crucial to prevent environmental harm. Used oil should be collected and recycled or disposed of through designated facilities. It’s also essential to check local regulations regarding used oil disposal to ensure compliance.
