You can drive your vehicle in such a way thatmay lead to higher oil consumption includingextended time at high engine speeds, highloads, engine braking, hard corneringmaneuvers, track and off-road usage. Underthese conditions, oil consumption ofapproximately 1 quart per 500 miles (1 literper 800 km) is possible.
