* For warmer climates (above 32°F or 0°C): 10W-30 is a common and often recommended viscosity.
* For colder climates (below 32°F or 0°C): 5W-30 is a better choice to ensure easier starting in cold weather.
Always check your owner's manual for the manufacturer's specific recommendation. The manual will likely specify the viscosity grades and the API (American Petroleum Institute) service classifications (like SG, SH, SJ, etc.) Using the wrong viscosity or API classification can harm your engine.
