I was getting around 23.5 - 24.5 mpg city/highway combined and 30 on the highway when I first bought my car a couple of months ago. I ran a bottle of fuel system cleaner through it and started running mostly Shell Vpower and have increased to 26.5-27.5mpg. I got 32mpg from Chicago to Fort Wayne a little after starting the Vpower binge but havent been on a long enough road trip the last few weeks to see if the hwy mileage improved anymore than 32.
Hope ya get it all ironed out. I smother over fuel mileage and would be going bonkers.
