Does the Lexus LS require premium gas?
Yes, the Lexus LS luxury sedan does require premium gasoline, typically 91 octane or higher. This is a common requirement for high-performance engines found in many luxury and sports cars.
Lexus LS Engine and Fuel Requirements
The Lexus LS is powered by a powerful V6 or V8 engine, depending on the model. These engines are designed to operate most efficiently and deliver maximum performance when using premium fuel. The use of lower-octane regular gasoline can lead to engine knocking, reduced power, and potentially even long-term damage to the engine components.
Lexus recommends that LS owners always use 91 octane or higher gasoline to ensure the vehicle runs as intended by the manufacturer. Using the proper fuel grade is essential for maintaining the Lexus LS's performance, fuel efficiency, and long-term reliability.
Why Premium Fuel is Recommended
- Engine Design: The Lexus LS engine is engineered to take advantage of the higher octane rating of premium fuel, allowing for increased compression ratios and more advanced ignition timing for better power and efficiency.
- Fuel Efficiency: Premium gasoline typically has a higher energy density than regular fuel, meaning the engine can extract more power from each gallon, leading to better fuel economy.
- Reduced Emissions: The cleaner-burning properties of premium fuel can also help reduce tailpipe emissions and keep the engine's fuel system cleaner over time.
While the Lexus LS can technically run on regular 87 octane gasoline, it is not recommended by the manufacturer. Using the wrong fuel grade can result in a noticeable decrease in performance, fuel economy, and potentially cause long-term damage to the engine.
Conclusion
In summary, the Lexus LS requires the use of premium 91 octane or higher gasoline to operate as intended by the manufacturer. Using the proper fuel grade is essential for maintaining the vehicle's performance, efficiency, and long-term reliability. Lexus strongly advises LS owners to always fill up with premium fuel for the best driving experience.
