Fuel economy is very much a driving style and conditions thing. The vehicle is quite heavy, so if there is a lot of stop and go, it won't 'go' very far on a tank. It excels at steady-state driving, like most any other vehicle. Beating everyone from the stop light and not anticipating a red light and jumping on the brakes at the last moment make the worst out of a bad situation. Cold starts verses running longer make a big difference as can idling. The vehicle is designed to turn on and start driving...not to sit idling. Course, none of these may apply to your situation, but are common things that affect mileage.

I'm not conversant in the different methods of rating octane, but RON of 95 may be excessive, and a lower grade may work just as well for less money. The manual calls for a minimum of 91, but uses a different grading scale...not sure of the conversion factors.
