High Mileage Oil for Your Car Engine: Expert Tips and Benefits
The "W" stands for winter, and the number before it indicates how the oil behaves in cold temperatures. 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.
The combination of letters and numbers, such as 5W-30 or 10W-40, refers to the oil's viscosity, or its resistance to flow. Ignoring these recommendations can lead to poor fuel economy, reduced engine performance, or even voided warranties.
High Mileage Oil for Enhanced Engine Protection and Performance
If you frequently make short trips, drive in stop-and-go traffic, or operate your vehicle in dusty conditions, your engine works harder and oil breaks down faster. Synthetic oil, on the other hand, is engineered in a laboratory to provide a more consistent molecular structure.
