Selecting the appropriate oil for your Toyota FJ Cruiser is crucial for maintaining engine health and performance. The recommended oil type varies based on the model year, operating conditions, and regional specifications.
Recommended Oil Types by Model Year
- 2007-2009 Models: Toyota recommends using 5W-30 oil for FJ Cruisers manufactured between 2007 and 2009. This viscosity provides adequate protection across a broad temperature range.
- 2010-2014 Models: For models produced from 2010 onwards, 0W-20 synthetic oil is the specified choice. This lower viscosity oil offers improved fuel efficiency and better engine performance, especially in colder climates.

Synthetic vs. Conventional Oil
While conventional oils were commonly used in older vehicles, synthetic oils have become the standard due to their superior properties, including better lubrication, higher resistance to oxidation, and improved performance in extreme temperatures. For the FJ Cruiser, using synthetic oil is recommended to ensure optimal engine protection and efficiency.

Considerations for High-Mileage Engines
As engines accumulate mileage, internal components may experience wear, potentially leading to oil consumption or leaks. In such cases, switching to a high-mileage synthetic oil can be beneficial. These oils contain additives designed to condition engine seals and reduce oil consumption, thereby extending engine life.
Oil Change Intervals
Regular oil changes are vital for maintaining engine health. For FJ Cruisers using synthetic oil, it’s advisable to change the oil every 5,000 to 7,500 miles, depending on driving conditions. Vehicles subjected to severe driving conditions, such as frequent short trips, towing, or extreme temperatures, may require more frequent oil changes.
FAQs
- Can I use 5W-30 oil in my 2010 FJ Cruiser?
- While 5W-30 was recommended for earlier models, the 2010 FJ Cruiser is designed to use 0W-20 synthetic oil for optimal performance and fuel efficiency.
- Is it necessary to use synthetic oil in my FJ Cruiser?
- Yes, Toyota recommends using synthetic oil, particularly 0W-20, for newer FJ Cruiser models to ensure proper engine lubrication and efficiency.
- What happens if I use a different oil viscosity than recommended?
- Using oil with a viscosity different from the manufacturer’s recommendation can lead to inadequate lubrication, increased engine wear, and decreased performance.
- How often should I change the oil in my FJ Cruiser?
- For vehicles using synthetic oil, it’s recommended to change the oil every 5,000 to 7,500 miles, depending on driving habits and conditions.
- Can I switch back to conventional oil after using synthetic oil?
- While it’s technically possible, it’s not recommended. Synthetic oils provide superior protection and performance benefits compared to conventional oils.
