While you can use 10W50 instead of 20W50, it's important to consider your vehicle's specific needs and the ambient temperature. 10W50 has a lower viscosity when cold, making it better for cold starts, but both have a similar high-temperature viscosity. Always check your vehicle's manual or consult with a professional to ensure the switch won't harm your engine, especially if you live in a hot climate or if your vehicle operates under heavy loads.
