Gasoline Engines
Gasoline engines are common in riding lawnmowers due to their relatively low cost and ease of maintenance. These engines typically require a standard motor oil, which is typically classified by its viscosity and API rating.
Viscosity
Viscosity refers to the oil’s thickness. The higher the viscosity, the thicker the oil. For gasoline engines, viscosity is expressed using a SAE (Society of Automotive Engineers) rating. This rating is often represented as two numbers separated by a “W,” for example, 10W-30. The first number (10W in this case) indicates the oil’s viscosity at cold temperatures, while the second number (30) indicates its viscosity at operating temperatures.
API Rating
The API (American Petroleum Institute) rating tells you the quality and performance characteristics of the oil. The higher the API rating, the more advanced the oil’s performance features. For modern gasoline engine lawnmowers, look for an oil with an SN or SM rating, indicating a high-quality, multi-grade oil.
Diesel Engines
Diesel engines, while less common in riding lawnmowers, are known for their power and efficiency. These engines often require a specific type of oil formulated for their unique operating conditions.
Viscosity
Diesel engines, due to their higher operating temperatures, typically require oils with higher viscosity ratings, such as 15W-40 or 20W-50.
API Rating
Diesel engines require oils with specific API ratings designed for their high compression and combustion conditions. The common API rating for diesel engines in lawnmowers is CJ-4.
