Great gas mileage, I don't ever recall getting 27 plus mpg with the OEM air filters. I don't know how accurate the MB computers are but I know I visit the gas stations less often now. The drive home from work is 11 miles, mostly local roads with 35mph speed limit. Here are my results, it was actually 27.9, but when I went inside the house to get my camera, it dropped down to 27.3, still very impressive.
