Why Use Synthetic Oil?
Synthetic oil offers numerous advantages:
- Better temperature resistance
- Improved lubrication and reduced engine wear
- Longer intervals between oil changes
- Enhanced engine performance and cleanliness
If you’re in a pinch and only have conventional oil, it can be used temporarily. However, Toyota advises switching back to synthetic as soon as possible.
How Often Should You Change the Oil?
Toyota suggests changing the oil every 10,000 miles or 12 months, whichever comes first if using synthetic oil. However, for severe driving conditions such as towing, frequent short trips, or extreme climates, consider changing the oil every 5,000 miles for better protection.
