Purchased vechile and consistently gets 3 to 4 mpg below EPA listing in all situations-City, highway, overall. Dealership made some adjustments and replaced mass air flow sensor. All to no avail. Mazda tech was contacted. Engine data faxed to Mazda. Everything in specs. Contacted Mazda by phone and letter. Stated I did not have a problem. That EPA listings were not to be believed. Had researched Mazda 5 prior to purchase-Automotive magazines, online articles, etc. All listed mileage 3 to 5 mpg more than what I am getting. I presently get 17-18 mpg in city driving, 24 highway driving, and around 20 mpg overall. Not what was and is expected!!!!
