* 5W-20: This is likely the recommended weight for most climates, especially those with moderate temperatures. It offers good cold-weather protection and decent viscosity at higher temperatures.
* 10W-30: This is a heavier weight oil and might be recommended for hotter climates or if you frequently tow or haul heavy loads. It provides better lubrication at high temperatures but may be slightly thicker when cold.
Always check your owner's manual. The specific recommendation will be listed there, taking into account the engine's design and the manufacturer's specifications. Using the wrong weight oil can negatively affect engine performance and longevity.
