Hi,
Considering Denali and I wonder if you could share your real MPG on your Denali? City:Highway = 60%: 40% able to get around 18mpg?
Another note: I find that driving style has a big impact on fuel economy regardless of engine size. (1) Maintain constant speeds as much as possible; (2) accelerate gently/slowly. I regularly use cruise control - even at low speeds - in order to maintain a constant speed AND to avoid receiving tickets from the police for driving faster than the speed limit . In my opinion (not educated opinion), driving at a constant speed promotes higher MPGs. My "lifetime" MPG according to the 2016 Yukon Denalis' computer is 18.5 MPG. I am not an aggressive driver. I drive at the speed limit. I accelerate gradually rather than aggressively. I want to prolong the life of my SUV's engine. The only time that I use "full throttle" is in an emergency situation to avoid an accident. I try never to "floor" the pedal and engine. I do "floor" it when there is an emergency situation and I am unable to know how much throttle to apply. Outside of emergency situations, I try to accelerate gradually and thus (I think) preserve the life of the engine. I also deliberately change engine oil ahead of the recommended schedule. I follow, if not exceed, the recommendations of the manufacturer for maintenance. I live in Illinois. I drive in places where the temperature is many degrees below freezing during the winter. Sometimes I take long trips and drive late at night. I thus want/need a reliable vehicle. I also have a philosophy of buying only American vehicles, despite some of their parts coming from non-US countries. I also invest in maintenance that is better than what is recommended by the manufacturer. I enjoy my 2016 Yukon Denali. I do wish that it had a smoother ride. And I wish also that it had the more sophisticated AWD technology of the GMC Acadia Denali and/or the multiple vehicles from Audi. But I am staying with my old-school body-on-frame 2016 Yukon Denali. I thoroughly enjoy the high levels of torque and the smoothness of the 6.2 liter V8 engine. For all engine fluids and maintenance other than oil, my plan is to provide maintenance that is better than what is recommended by the manufacturer. The owner's manual recommends applying 3/4 throttle in situations that require extra throttle. However, in an emergency, I am not able to constrain the pressure of my foot to 3/4 throttle. I thus apply in emergency situations the full throttle. That is not good for lifetime survival of the engine. But I am not able train myself in emergency situations to constrain myself to using 3/4 throttle.
