My own 2.0 Liter DOHC 1998 ATX Zetec gets 25 around town and 33 on the highway. It runs perfect. My fatherin law's 2.5L SE ATX 1998 with only 22,000 miles and no problems gets 20 to 22 in town. I dont believe anyone claiming fantastic mileage for these cars. MPG claims might sound attractive and get you to buy, but the reality is always lower.
Anyone ever heard of water injection to help mpg?
