The owner's manual will specify:
* Oil type: This will likely be either conventional, synthetic blend, or fully synthetic.
* Oil weight: This will be a number like 5W-20, 5W-30, or 10W-30. The weight recommended will depend on your climate and driving conditions.
Do not guess. Using the incorrect oil can severely damage your engine. Consult your owner's manual or a qualified mechanic to ensure you use the proper oil.
