The vast majority of Husqvarna lawn mowers use 4-stroke engines. These engines require a separate oil reservoir, and the oil is used to lubricate moving parts and cool the engine.
2-Stroke Engines: A Different Approach
2-stroke engines, while less common, are still found in some Husqvarna lawn mowers, particularly older models. They mix oil directly with gasoline in a specific ratio before use.
Choosing the Right Oil: Essential Factors
Once you know your engine type, you can narrow down the oil options. Here are the key factors to consider:
1. Oil Viscosity: A Measure of Thickness
Oil viscosity refers to its thickness. The SAE (Society of Automotive Engineers) rating system classifies oil viscosity using numbers like 10W-30, 5W-30, or simply 30. The first number (e.g., 10W) represents the oil’s viscosity at cold temperatures, and the second number (e.g., 30) represents its viscosity at operating temperatures.
For Husqvarna lawn mowers, a common recommendation is SAE 30 oil, which is designed for warmer temperatures and provides sufficient lubrication. However, consult your owner’s manual for specific recommendations based on your mower’s engine type and operating environment.
2. Oil Type: Synthetic or Conventional?
Synthetic Oils: High Performance and Durability
Synthetic oils are engineered in a lab and offer several advantages over conventional oils:
