8°C) and indicates how well the oil will flow when you start your engine on a freezing morning. A higher number indicates greater resistance to thinning out under stress.
Synthetic Oil Numbers Vs Conventional: What The Viscosity Codes Mean For Your Engine
Understanding what the numbers on oil mean is essential for anyone who owns a vehicle. Conversely, oil that is too thin may not provide a sufficient lubricating film, leading to increased metal-on-metal contact and potential wear.
As a result, synthetic blends or full synthetics frequently maintain their viscosity more effectively in both extreme heat and cold. For example, 5W-30 flows more easily at cold temperatures than 15W-40, making it more suitable for harsh winter climates.
Synthetic vs Conventional Oil Viscosity Numbers Explained
The designation provides critical information about viscosity, or the oil's resistance to flow, ensuring your engine operates smoothly under varying temperature conditions. Understanding the Temperature Ranges The number following the "W" represents the oil's viscosity at 210°F (100°C), which is the typical operating temperature of a running engine.
