As the engine warms up, the oil reaches its optimal operating viscosity, providing the necessary protection against thermal breakdown and oxidation. For drivers who subject their vehicles to extreme temperatures, frequent towing, or prolonged idling, investing in a synthetic formulation is generally the superior option.

This thermal stability translates directly to fuel efficiency, as the engine does not have to work as hard to overcome internal friction. The number 30 following the hyphen refers to the oil's viscosity at the engine's normal operating temperature of 100°C.
Using an incorrect viscosity can lead to poor performance, increased oil consumption, or even severe engine damage over time. Not all diesel engines are designed for this viscosity; some heavy-duty or high-mileage engines may require a heavier grade like 15W-40 or 20W-50 to maintain adequate oil pressure and lubrication.

Synthetic blends offer a middle ground, enhancing performance and protection at a reasonable price point. The "W" stands for winter, and the number preceding it indicates the oil's cold-start viscosity.
