Does the Lexus RX 350 require premium gas?
The Lexus RX 350 is a popular luxury SUV, and one common question owners have is whether the vehicle requires premium gasoline. The short answer is yes, the Lexus RX 350 does require premium fuel, typically 91 octane or higher.
Lexus RX 350 Fuel Requirements
According to the Lexus owner's manual, the recommended fuel for the RX 350 is premium unleaded gasoline with a minimum octane rating of 91. Lexus engineers have designed the engine in the RX 350 to perform optimally with higher-octane premium fuel. Using regular gasoline, which has a lower octane rating, can potentially cause engine knocking or pinging, which can lead to reduced performance and fuel efficiency.
It's important to note that while the RX 350 can technically run on regular 87 octane fuel, Lexus strongly recommends against doing so. Using the wrong fuel type can cause long-term damage to the engine and other components, ultimately leading to more expensive repairs down the line.
Benefits of Using Premium Fuel
- Improved Performance: Premium gasoline has a higher octane rating, which allows the engine to run at higher compression ratios without experiencing knocking or pinging. This results in more power and acceleration.
- Better Fuel Efficiency: The higher octane rating of premium fuel can also lead to improved fuel economy, as the engine can operate more efficiently.
- Reduced Emissions: Premium gasoline often contains fewer impurities and additives, which can help reduce emissions and be better for the environment.
- Longer Engine Life: Using the recommended premium fuel can help protect the engine from wear and tear, potentially extending the lifespan of the vehicle.
While the higher cost of premium fuel may be a consideration, the benefits it provides for the Lexus RX 350 make it a worthwhile investment for most owners. Proper fuel maintenance is essential for ensuring the longevity and performance of this luxury SUV.

If you use regular gas, the high-compression engine may become more likely to detonate. While one fill-up with regular gas isn't expected to cause long-term damage, this repeated habit can lead to the need of severe repairs or an entire engine replacement.
