However, using the right grade of gas, as the company recommends, will reduce the chances of your car getting damaged and help you achieve optimal performance with the car.
Does Lexus RX Require Premium Gas? Lexus RX models don’t require premium gas. They require unleaded gasoline with an octane rating of 87 and above. However, using gasoline with a higher octane rating than 87 won’t hurt. Instead, it will improve the car’s power and performance.
For those who drive Luxury brands like Lexus cars, it’s always thought their cars require premium gas because of the high-compression engine they feature, which is mostly the case. However, for the Lexus RX models, the required grade is an octane rating of 87 and above.
Using any gas with a lower octane grade than 87 in a Lexus RX can reduce the car’s power and performance and also knock the car’s engine.
What Type Of Gas Does The Lexus RX Require?
Lexus RX models require regular unleaded gas with an octane rating of 87 or higher. They do not necessarily require premium gas of 91-octane like some other Lexus models.
Although you can decide to fill your Lexus RX with premium high-octane gas if you wish. It won’t cause any harm to your car but rather might just improve the car’s performance. However, it’s not needed.
You mustn’t use gas with a lower octane rating than 87 in an RX, as it harms the car’s engine.
Also, using the recommended type of gas in your Lexus RX helps with fuel efficiency. Gas with a lower octane rating than 87 in a Lexus RX will combust too quickly.
Lexus recommends avoiding gasoline that contains methanol and ethanol content of over 15%.
Gasoline with methanol is bad for your car and should be avoided. Likewise, gasoline with an ethanol content of over 15% should be avoided as it will undoubtedly damage your car.
What Type Of Gas Do Lexus Cars Require?
The type of fuel a Lexus car requires depends on the model.
Many Lexus car owners assume their car requires premium gasoline with a 91 octane rating because Lexus is a luxury brand. However, this isn’t entirely true.
For Lexus cars such as the RX, you must use unleaded gas with an octane rating of at least 87 or higher, although this doesn’t apply to all Lexus cars. Some will require a premium 91-octane gas as the minimum.
When it’s recommended that a car should use a specific type or octane rating of gas, it means the car was designed to operate best with that type of gas.
Filling up a car with a higher octane gas rating than the required type won’t damage the car. It might even improve the performance of the car.
However, a lower rating than the required rating should never be used because this can damage the car’s engine.
Therefore, it’s important to be sure about the type of gas your car needs, and if you’re unsure, it’s better to confirm from your car owner’s manual.
