A 5W rating means the oil flows well at low temperatures, typically down to around -30°C, ensuring the engine receives lubrication immediately on startup when wear is most likely to occur. This translates to longer oil change intervals, with many manufacturers recommending changes every 10,000 to 15,000 miles for synthetics, compared to 3,000 to 5,000 miles for conventional oils.
