Fuel Requirements for the Lexus GX 550

- Engine Knock Prevention: Higher octane fuel helps prevent engine knocking, which can occur when the air-fuel mixture ignites prematurely. This is particularly important for high-performance engines like that of the GX 550.
Benefits of Using Premium Gas
While premium gasoline typically costs more than regular, the benefits can outweigh the additional expense for owners of the Lexus GX 550. Here are some advantages:

Conclusion
In summary, while the Lexus GX 550 can technically run on regular gasoline, it is highly recommended to use premium unleaded fuel to ensure optimal performance and longevity of the vehicle.
