The "W" stands for winter, and the number before it indicates how the oil behaves in cold temperatures. The manufacturer specifies the exact oil viscosity and performance standards required for your specific engine.
Understanding Oil Change Intervals and the Right Viscosity for Your Car
Viscosity Grade Best For Typical Performance 5W-20 New economy cars Excellent fuel economy, cold protection 5W-30 Most modern vehicles Balanced protection and efficiency 10W-40 Older engines or warm climates High temperature stability Driving Habits and Climate Considerations Your driving environment and style play a significant role in the question of what oil to use. The combination of letters and numbers, such as 5W-30 or 10W-40, refers to the oil's viscosity, or its resistance to flow.
Choosing the right oil for your car is one of the most important decisions you can make for its longevity and performance. Similarly, if you live in a region with harsh winters, a 0W or 5W oil is essential to ensure the engine turns over easily.
Understanding Oil Change Intervals and the Best Schedule for Your Car
Look for the API (American Petroleum Institute) starburst symbol on the bottle, which certifies that the oil meets the minimum service standards for your engine, such as SN or the newer SP rating, which offer better protection against sludge and wear. This results in superior performance, better resistance to breakdown, enhanced protection in extreme temperatures, and improved fuel efficiency.
