- 2-stroke engines: These mix oil and fuel directly in the gas tank.
Knowing your engine type is crucial because oil requirements differ significantly between the two.
2. Oil Viscosity:
- SAE (Society of Automotive Engineers): The SAE rating indicates the oil’s viscosity, which impacts its thickness at different temperatures.
- Multigrade oil: These oils offer good performance across a wider temperature range, designated by a “W” (Winter) and a number for high-temperature viscosity. For example, 10W-30 oil is suitable for various weather conditions.
Your owner’s manual will specify the recommended viscosity range for your mower’s engine.
3. Oil Type:
- Conventional oil: The most affordable option, often refined from crude oil.
- Synthetic oil: Engineered for superior performance and longevity, often more expensive.
- Synthetic blend: Offers a balance of cost and performance, blending conventional and synthetic oils.
While conventional oil might suffice for basic maintenance, synthetic oils offer several advantages, including better wear protection, higher heat tolerance, and increased engine life.
The Types of Oil for Lawn Mowers: Exploring the Options
