What oil weight should be used in a Honda odyssey 2005 with high mileage?

For a 2005 Honda Odyssey with high mileage, it's generally recommended to use a 5W-20 motor oil. However, if the engine shows signs of wear or has significant oil consumption, you might consider using a high-mileage oil specifically formulated for older engines, which often has additives to help reduce leaks and consumption. Always check the owner's manual for specific recommendations and consider consulting with a mechanic for personalized advice based on your vehicle's condition.
