SAE 20W-50: This oil is recommended for use in hot weather or for very high-mileage engines. It provides a little more protection for the engine than 10W-40, but it is also thicker and can result in slightly reduced fuel economy.
SAE 5W-30: This oil is recommended for use in extremely cold weather. It is thinner than 10W-40 and 20W-50, and it flows more easily at low temperatures. This can help protect the engine from damage during startup.
Here are some other specifications that you may want to look for in a Honda VTX 1300:
- API Service Category: SL or higher
- JASO MA: This means the oil is specifically designed for motorcycles.
- SAE Viscosity Grade: The viscosity grade indicates the oil's thickness at different temperatures. The higher the number, the thicker the oil.
