The 2011 Scion xB's 2.4-liter 2AZ-FE engine requires SAE 5W-20 motor oil, with a capacity of about 4.8 quarts (roughly 4.6 liters) including the filter. Synthetic or synthetic-blend oil that's API SN or GF-5 compliant is recommended.
In this guide, we outline the official specifications, practical options for oil choice, and maintenance tips to keep the engine properly lubricated. You’ll find details on the recommended grade, capacity, climate considerations, and how to verify oil levels during service.
Oil specifications for the 2AZ-FE engine
These are the core specifications you should follow for the 2011 xB with the 2AZ-FE engine. The information reflects standard guidance used by Toyota/Scion for this model year.
- Recommended oil grade: SAE 5W-20 (synthetic-blend or full synthetic).
- Oil specification: API SN or newer; ILSAC GF-5 compliant.
- Oil capacity: Approximately 4.8 quarts (about 4.5–4.8 L) with filter.
- Oil filter: Use a compatible oil filter designed for the 2AZ-FE engine.
Concluding note: Start with about 4.8 quarts, then check the dipstick and top off gradually to reach the full mark, avoiding overfill.
Climate considerations and oil choice
While 5W-20 is the standard grade for most driving conditions, some drivers in hotter climates or with demanding workloads may opt for 5W-30. Always check the owner's manual and local service recommendations, and choose the grade that matches your climate and driving style.
Concluding tip: Use the grade that best matches your climate and driving habits, and ensure the oil meets API and ILSAC specifications.
Maintenance and checking the oil level
Regular checks and timely oil changes are essential for the 2AZ-FE. Here are practical steps to maintain proper oil levels and quality.
- Check the oil level when the engine is cool and on level ground, using the dipstick with the markings.
- Change intervals typically range from 5,000–7,500 miles with conventional oil, or up to 10,000 miles with high-quality synthetic oil, depending on usage and climate.
- Use the correct filter and ensure a proper seal when installing a new filter.
- Avoid overfilling; add oil in small increments and recheck to stay within the full-mark range.
Concluding paragraph: Consistent oil changes and accurate level checks help maintain the 2AZ-FE's longevity and performance.

What kind of motor oil does a Scion xB take?
Mobil 1 – High Mileage 0W-20 Full Synthetic Motor Oil, Extends Engine Life, 5 Quart (Part No. 15015)
Should I use 5W or 0W oil?
The 0W or 5W refers to the pumpability in cold temperatures. Therefore, a 0W would flow more easily than a 5W and could be an acceptable substitute. Thus, it is suitable to use a SAE 0W-20 as a replacement for SAE 5W-20 application. **Offers same protection as 5W but also provides faster flow and better fuel economy.
