Oil Maintenance & Service Tips
Always check the oil level using the dipstick when the engine is warm and parked on level ground. Replace the oil filter at every oil change to ensure maximum filtration and engine protection. For best results, use full synthetic oil as recommended by Toyota. The oil change interval is typically every 7,500–10,000 miles or 12 months for modern Siennas, but more frequent changes may be needed for severe driving conditions such as frequent short trips, towing, or extreme temperatures.
| Condition | Recommended Oil Change Interval |
|---|---|
| Normal Driving | Every 7,500–10,000 miles or 12 months |
| Severe Driving | Every 5,000 miles or 6 months |
