Why the Lexus GS 350 Requires Premium Fuel
The Lexus GS 350 is a luxury sedan with a powerful 3.5-liter V6 engine.

Using regular gas in a Lexus GS 350 can have several negative consequences:
- Reduced engine performance: The engine may experience a noticeable loss of power and acceleration.
- Decreased fuel efficiency: The engine may not be able to operate as efficiently, leading to lower miles per gallon.
- Potential engine damage: Over time, the use of regular gas can cause engine knocking, which can lead to serious damage to the engine components.
In addition, using regular gas in a Lexus GS 350 may also void the vehicle's warranty, as it goes against the manufacturer's recommendations.
