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.
