Conversely, the number 40 denotes the oil's viscosity at 100°C. This can reduce oil consumption and external leaks without sacrificing the protective qualities associated with this viscosity.

Its moderate weight also contributes to better fuel efficiency compared to heavier oils. This reduces friction, which in turn lowers operating temperatures and minimizes the accumulation of harmful deposits.
This high-temperature rating ensures the oil maintains a robust film strength to prevent metal-to-metal contact, even when the engine is working hard in hot climates or during towing. Monitoring the oil level regularly and looking for signs of contamination, such as a milky appearance or metallic particles, is essential for engine health.
