The recommended viscosity for your Craftsman lawn mower is usually specified in your owner’s manual. It often uses a SAE (Society of Automotive Engineers) rating, such as SAE 10W-30.
- W: The “W” stands for “Winter.” The number before the “W” indicates the oil’s viscosity at cold temperatures. A lower number means the oil flows more easily in cold weather.
- Second number: This number indicates the oil’s viscosity at operating temperatures. A higher number means the oil is thicker at high temperatures.
Common Viscosities:
- SAE 10W-30: A versatile oil suitable for a wide range of temperatures.
- SAE 5W-30: Good for cold weather starting.
- SAE 30: Suitable for hotter climates.
3. Oil Quality:
Engine oil is graded based on its quality and performance. The most common grading system is the American Petroleum Institute (API) service classification.
- API Service Classification: This system uses letters and numbers to indicate the oil’s quality and performance characteristics. For example, “SN” indicates a high-quality oil designed for modern gasoline engines.
Always refer to your Craftsman owner’s manual for the recommended API service classification.
4. Oil Additives:
Engine oils often contain additives that enhance their performance, such as:
- Detergents: Help keep the engine clean by suspending contaminants.
