* Check your owner's manual: This will provide the most accurate information regarding the recommended oil type, viscosity, and API certification for your specific vehicle.
* Look at the oil cap: The oil cap on your engine may have a sticker with the recommended oil type and viscosity.
* Consult a Toyota dealership or a qualified mechanic: They can give you specific recommendations for your Corolla based on its engine size and other factors.
General Guidelines:
* API Certification: Look for oil with an API certification, typically "SN" or higher for gasoline engines.
* Viscosity: The correct viscosity will be listed in your owner's manual, but common viscosity ranges for Toyotas are 0W-20, 5W-20, or 5W-30.
Important Note: Using the wrong type of oil can harm your engine. Always consult your owner's manual or a trusted mechanic before changing your oil.
