Understanding Lawn Mower Engine Oil
Lawn mower engines, like any other small engine, require oil to lubricate moving parts, cool the engine, and clean the engine by carrying away contaminants. The oil viscosity, which is a measure of its thickness and flowability, is crucial because it affects how well the oil can perform these functions under different temperature conditions. Viscosity is typically measured by its thickness in cold temperatures (the “W” rating, which stands for winter) and its thickness in warm temperatures (the non-W rating). For example, a 10W-30 oil is thinner in cold temperatures (for easier starting and quicker oil flow to critical engine parts) and thicker in warm temperatures (for better lubrication).
Viscosity and Its Importance
Viscosity is a critical factor because thicker oils provide better lubrication but can be harder to pump in cold temperatures, while thinner oils are easier to pump in cold conditions but may not provide sufficient lubrication when the engine is hot. Therefore, the ideal oil viscosity for your lawn mower depends on the climate you live in and the specific recommendations of your lawn mower’s manufacturer.
