Does the Lexus GS350 require premium gas?
Yes, the Lexus GS350 requires premium gasoline, typically 91 octane or higher. This is a common requirement for many luxury and high-performance vehicles to ensure optimal engine performance and fuel efficiency.
Lexus GS350 Fuel Requirements
The Lexus GS350 is a midsize luxury sedan known for its smooth ride, powerful engine, and premium features. As a high-end vehicle, the GS350 is designed to run on premium fuel, which is typically more expensive than regular gasoline. This is because premium fuel has a higher octane rating, typically 91 or 93, compared to regular gasoline, which is usually 87 octane.
The higher octane rating of premium fuel helps prevent engine knocking and pre-ignition, which can occur in high-performance engines like the one found in the Lexus GS350. Using a lower octane fuel can lead to decreased power, reduced fuel efficiency, and potentially cause long-term damage to the engine.
Consequences of Using Regular Gasoline
- Decreased Performance: The Lexus GS350's engine is tuned to perform optimally with premium fuel. Using regular gasoline can result in a noticeable decrease in power and acceleration.
- Reduced Fuel Efficiency: Premium fuel is designed to burn more efficiently, which can improve fuel economy. Using regular gas may result in slightly lower miles per gallon.
- Engine Damage: In the long run, consistently using a lower octane fuel than recommended can lead to engine knocking, pre-ignition, and other issues that may cause significant damage to the engine over time.
It's important to always refer to the owner's manual for the Lexus GS350 and use the recommended premium fuel to ensure the best performance, fuel efficiency, and long-term engine health.

To confirm the correct fuel for a specific vehicle, always check the owner's manual or the vehicle's fuel-door label.
