* Engine Condition: The ideal oil depends on the age and condition of your engine. An older engine may need a thicker oil to handle wear, while a newer one might benefit from a lighter weight.
* Driving Conditions: Where you live and how you drive matter. Extreme temperatures or frequent heavy loads might call for different viscosity oils.
* Manufacturer Recommendations: Your Toyota owner's manual will provide the most accurate guidance on the recommended oil viscosity and type.
Here's a general guide:
* Viscosity: For most 22R engines, 10W-30 is a good starting point.
* Type: Consider a conventional oil (less expensive) or a synthetic oil (better performance and longevity, especially in extreme conditions).
* API Certification: Look for oils with an API certification (American Petroleum Institute) that meets or exceeds the requirements for your engine.
Always consult your Toyota owner's manual and any relevant service bulletins for the most accurate oil recommendations.
Additionally:
* Consider using a high-quality oil filter.
* Change your oil regularly. This is critical for maintaining engine health.
I hope this helps!
