This reduces friction, which in turn lowers operating temperatures and minimizes the accumulation of harmful deposits. Its moderate weight also contributes to better fuel efficiency compared to heavier oils.

The "W" stands for winter, and the number preceding it indicates the oil's cold-flow properties. This adaptability translates directly into engine longevity.
In summer, the high-temperature stability prevents the oil from thinning too much, protecting the engine during extended highway driving or heavy cargo transport. In winter, the low-temperature fluidity reduces the strain on the battery and starter motor, while the quick circulation ensures rapid lubrication during the most critical phase of engine operation.
