My previous car was a 1983 Volvo 4 cycl and the best I got out of it was 33 mpg, and that was when I picked it up in Jacksonville Fl. During the almost 21 years I had the car I got always around 22-24 mpg (open road driving). My current car is a 1999 Jeep Grand (Limited). The EPA rated it for 19/21. In the city I've driven it over 20 and the best I've driven it on the Interstate is 25. I have to admit I cheat sometimes in the summer I drive allot with my windows half down. I live along the Mississippi gulf coast and we get some mighty HOT! days.
