During cold weather or when the engine is first started, the "10W" ensures the oil circulates rapidly through the crankshaft and bearings, reducing dry friction and minimizing startup wear. As the engine reaches its normal operating temperature, the viscosity stabilizes to a "30" rating, creating a robust film that prevents metal-to-metal contact under high stress.
