Viscosity Grades Explained
Choosing the right engine oil involves understanding viscosity grades. Viscosity is the oil’s resistance to flow. This factor is crucial for engine performance and longevity.
Understanding Viscosity Ratings
Every bottle of engine oil comes marked with codes like “5W-30” or “10W-40.” You might wonder what these numbers mean. They are viscosity ratings that tell you how the oil performs in different temperatures.
The first number ends with a ‘W’, which stands for winter. It measures how oil flows when it’s cold. The second number shows the oil’s thickness at high temperatures.
A lower ‘W’ number means the oil flows better in the cold. The higher the second number, the thicker the oil stays under heat.
Why The Right Viscosity Matters
Engines need oil that flows quickly when cold to reduce wear during start-up. But that oil must also protect engine parts at high temperatures. The correct viscosity ensures this balance.
Imagine syrup on a cold vs. a hot day. Engine oil works similarly. Choose a grade that suits your climate and driving conditions to keep your engine running smoothly.
Consult your vehicle’s manual for the manufacturer’s recommended viscosity.
A mismatch in viscosity can lead to increased friction, overheating, and even engine failure. Always select the appropriate viscosity for your car’s specific needs.
