It also possesses a much higher resistance to oxidation, meaning it breaks down far more slowly under the thermal stress of modern engines. Not all engines are designed to accommodate the higher detergent levels and different additive packages found in synthetic formulations.

This resistance to thermal degradation prevents the formation of harmful sludge and varnish, keeping critical oil passages clean and ensuring consistent lubrication over extended drain intervals that often exceed those recommended for conventional oils. The "W" stands for winter, and the "50" represents the high-temperature viscosity, measured at 100°C, indicating the oil's thickness and ability to maintain a protective film under intense heat and pressure.
Conversely, in hot climates or during high-load conditions such as towing or track driving, the high-temperature stability prevents the oil from thinning too much, maintaining a robust oil film that prevents metal-to-metal contact and protects bearings and camshafts.

The synthetic base stocks used in these formulations are engineered molecules designed for consistency, resulting in superior performance compared to mineral oils derived directly from crude. The "20" signifies the oil's low-temperature viscosity, or its ability to flow when the engine is cold, which is critical for protecting components during startup.
