Ok - at the suggestion of the dealer, It's gone through it's initial run in period, and still Im getting awful 28mpg for town driving. I registered my issues with them before the 30 day and I gave them the car to fix the problem - they have not fixed it. Frankly Im annoyed, I bought diesel for economy and given the way oil prices are going, I will need it! I really like the CMAX, so any advice?
