* 10W-30 is a good all-around choice for most climates. This is likely what the owner's manual recommends.
* 5W-30 is suitable for colder climates. It flows better in cold temperatures.
* 20W-50 is better suited for hotter climates. It provides better lubrication at high temperatures.
Always check your owner's manual for the manufacturer's specific recommendations. Using the wrong weight oil can damage your engine. The manual will specify the oil weight and type (conventional, synthetic blend, or full synthetic).
