3. Enhanced cold weather performance: As someone who lives in a region with harsh winters, I understand the importance of using oil that can withstand extreme temperatures. The “W” in 15 40W stands for winter, indicating that this type of oil has been designed to maintain its viscosity even in colder climates. This ensures proper lubrication during start-up when
