My 2.2 automatic has settled in at 24mpg (US) in town, but I am using unleaded plus. The cheap regular we have here gets about 20 in town, so it pays to use better gas. Not to mention the added power I feel. I saw 35 mpg on the hwy only one time. Most other was 28-30mpg, but don't do much hwy driving now since switching to better gas.
