This stability prevents the oil from thinning too much, which can lead to increased metal contact and degradation. This specific viscosity grade offers a balance of cold-start fluidity and high-temperature stability, making it a popular choice for both everyday commuter cars and performance vehicles.

Following the manufacturer’s guidance regarding API or ACEA ratings ensures the oil meets the necessary standards for shear stability and performance. How It Handles Heat and Stress Once the engine reaches normal operating temperature, the high viscosity index of synthetic 5w-40 oil maintains a stable film thickness.
Over the life of the oil, this cleanliness translates to better fuel economy, smoother operation, and a reduced likelihood of deposits interfering with valve train function or clogging oil passages. The extended change intervals reduce both the frequency of purchases and the labor associated with oil changes.
