Does the Lexus RX require premium gas?
The Lexus RX, a popular luxury SUV, does not require premium gasoline. The manufacturer recommends using regular unleaded gasoline with an octane rating of 87 or higher for the Lexus RX models.
Lexus RX Fuel Recommendations
According to the Lexus owner's manual, the recommended fuel for the Lexus RX is regular unleaded gasoline with an octane rating of 87 or higher. Lexus states that using premium fuel is not necessary for the RX models and will not provide any additional benefits in terms of performance or fuel economy.
The Lexus RX is designed to operate on regular gasoline, and the engine's computer system is calibrated to work optimally with 87 octane fuel. Using a higher octane premium fuel will not harm the engine, but it also won't improve the vehicle's power, acceleration, or fuel efficiency.
Why Some Drivers Use Premium Fuel
- Some drivers may choose to use premium fuel in the belief that it will provide better performance, even though it's not required for the Lexus RX.
- Premium fuel has a higher octane rating, which helps prevent engine knocking or pinging, especially in high-performance vehicles with high-compression engines.
- However, the Lexus RX does not have a high-performance engine that requires premium fuel to prevent knocking.
In summary, the Lexus RX manufacturer recommends using regular 87 octane gasoline, and there is no need to pay more for premium fuel, as it will not provide any tangible benefits for this particular vehicle.
