Lexus vehicles have varying requirements when it comes to fuel type. While some Lexus models do require premium gasoline, not all of them do. The fuel requirement depends on the specific model and year of the vehicle.
For example, the 2019 Lexus models fall into two categories: those that require premium gasoline and those that don’t. The models that fall into the first category require premium gasoline with an octane rating of 91 or higher, while the models in the latter category can use regular gasoline with an octane rating of 87 or lower.
Similarly, the Lexus RX does not require premium gasoline. The recommended octane rating for the RX is 87, but you are free to use premium gas if you prefer, as it may provide better performance.
On the other hand, the Lexus NX does require premium unleaded gasoline with an octane rating of 91 or higher. This ensures that the NX runs efficiently and provides the best possible performance.
It’s important to note that using premium gas in a vehicle that doesn’t require it will not increase mileage ratings or performance.
In summary, the fuel requirement for Lexus vehicles varies depending on the model and year. Some models require premium gasoline, while others can use regular gasoline. It’s always best to consult the owner’s manual or contact a Lexus dealership for the specific fuel requirements of your vehicle.
