Does Lexus ES require premium gas?
The short answer is yes, the Lexus ES does require premium gasoline. The Lexus ES is a luxury sedan that is designed to operate optimally with higher-octane premium fuel.
Lexus ES Engine and Fuel Requirements
The Lexus ES is powered by a 3.5-liter V6 engine that is designed to run on premium gasoline, which has a higher octane rating than regular gasoline. The recommended fuel for the Lexus ES is 91 octane or higher. Using a lower-octane fuel can potentially cause engine knocking or pinging, which can lead to long-term damage to the engine over time.
Lexus specifically recommends using premium gasoline in the ES model to ensure optimal performance, fuel efficiency, and engine longevity. The engine is tuned to take advantage of the higher octane rating of premium fuel, which allows for higher compression ratios and more advanced ignition timing.
Consequences of Using Regular Gasoline
- Reduced engine power and acceleration
- Decreased fuel efficiency
- Potential engine knocking or pinging, which can cause long-term damage
- Voiding of the vehicle's warranty if regular gasoline is used consistently
While it is possible to use regular 87 octane gasoline in the Lexus ES, it is not recommended by the manufacturer. Using the recommended premium fuel will ensure the best performance, fuel economy, and long-term engine health for your Lexus ES.
