I have asked the dealer (Van Buick Scottsdale, AZ) why is the car getting poor gas mileage. They checked the cars engine and told me that everything is set to factory settings. I can't see how that can be, my tail pipes are black!. I use 91pr gas and I have hydrogen in my tires, (35 lbs). I use a high grade oil and nothing improves my gas mileage. The dealer said after 5000 miles I would get better mileage, then 10,000 miles but still no change. I called GMC they said there was nothing they could do if the engine was set to the factory settings. The sticker said 17 city 24 highway, not true!

This 2011 car with low 50,000 miles does not meet the specified MPG of 16 city and 23 Highway. Instead we get an inefficient 15 in mixed conditions (we do not drive in a city) and 17 in Highway. Other owners report great gas mileage in the highway of 23-24 MPG. There are no diagnostic codes showing and this car is gently driven by my wife. .
