Do all Lexus RX 350 require premium gas?
The short answer is no, not all Lexus RX 350 models require premium gasoline. The fuel requirement for the Lexus RX 350 can vary depending on the specific model year and engine configuration.
Fuel Requirements for the Lexus RX 350
The Lexus RX 350 is a popular luxury crossover SUV that has been in production since 2003. Over the years, Lexus has made several updates and changes to the RX 350, including the engine and fuel requirements.
- 2003-2009 Lexus RX 350 models: These earlier RX 350 models are designed to run on regular unleaded gasoline (87 octane).
- 2010-2015 Lexus RX 350 models: Lexus recommends the use of premium unleaded gasoline (91 octane or higher) for these model years.
- 2016-present Lexus RX 350 models: Lexus again recommends the use of premium unleaded gasoline (91 octane or higher) for the latest generation of RX 350 models.
It's important to note that while Lexus recommends premium fuel for the 2010 and newer RX 350 models, the vehicle can still operate on regular unleaded gasoline. However, using regular fuel may result in a slight decrease in performance, fuel efficiency, and engine longevity compared to using the recommended premium fuel.
Reasons for Premium Fuel Recommendation
The primary reason Lexus recommends premium gasoline for the 2010 and newer RX 350 models is due to the engine's higher compression ratio and advanced technology. These engines are designed to take advantage of the higher octane rating of premium fuel, which helps prevent engine knocking and improves overall performance.
Additionally, the use of premium fuel can help maintain the engine's efficiency and longevity, as well as reduce emissions. Lexus engineers have optimized the RX 350's engine to perform best with premium gasoline, so it's generally recommended to follow the manufacturer's fuel requirements for the best driving experience and long-term engine health.
