Does the Lexus GS require premium?
Yes, the Lexus GS luxury sedan does require premium gasoline, typically 91 octane or higher. This is a common requirement for many high-performance vehicles to ensure optimal engine performance and efficiency.
Detailed Explanation
The Lexus GS is a mid-size luxury car known for its powerful engine options, smooth ride, and premium features. To power these advanced engines, Lexus recommends using premium unleaded gasoline with an octane rating of 91 or higher. This is because the higher octane fuel can withstand higher compression and temperatures without prematurely igniting, which is crucial for the GS's turbocharged or high-performance naturally aspirated engines.
Using a lower octane fuel, such as regular 87 octane gasoline, could result in engine knocking or pinging, which can cause damage over time. The higher octane premium fuel helps ensure the engine runs smoothly and efficiently, delivering the full performance and fuel economy the Lexus GS is designed for.
Consequences of Using Regular Fuel
- Reduced engine power and acceleration
- Decreased fuel efficiency
- Potential engine damage from knocking or pre-ignition over time
- Voiding of the vehicle's warranty if damage is caused by using improper fuel
While using regular 87 octane gasoline may save a few dollars per fill-up, it's generally not recommended for the Lexus GS. The small cost savings is outweighed by the potential long-term consequences of using the wrong fuel type, which could lead to expensive repairs and decreased performance.
Fuel Efficiency and Costs
The Lexus GS is rated for 23 mpg in the city and 31 mpg on the highway when using premium fuel. While premium gasoline is more expensive than regular, the improved fuel efficiency of the GS can help offset the higher per-gallon cost. Drivers can also take steps to maximize their fuel economy, such as maintaining proper tire pressure, avoiding aggressive acceleration, and keeping up with scheduled maintenance.
In summary, the Lexus GS requires premium gasoline with a minimum octane rating of 91 to ensure optimal engine performance, fuel efficiency, and long-term reliability. While the premium fuel may cost a bit more, it's a necessary expense to keep this luxury sedan running at its best.
