Mein Auto: 2007 328i sports wagon
More from the school of hard knocks. My 328 sportwagon got 22.6 mpg during the first 2,500 miles, and about 25.0 the next 23,000 with no change in city/highway percentages. I did see a posting on the Ford C-Max forums that if you look on a certain page in the OM it specifically says to ignore fuel economy during the first 2,500 miles. Interestingly the new C-Max so far is not delivering anything close to the EPA 47/47 (40.7 on

edit: It took a while, but I found the link: "page 196 of the C-MAX's owners's manual states "Do not measure fuel economy during the first 1000 miles (1600 kilometers) of driving (this is your engine's break-in period); a more accurate measurement is obtained after 2000 miles–3000 miles (3200 kilometers–4800 kilometers). Also, fuel expense, frequency of fill-ups or fuel gauge readings are not accurate ways to measure fuel economy.""
