I need some help. What kind of gas mileage is everyone getting? I have a 2001 S40 that I bought in November. When I got it I was using it to commute daily into NYC (real city driving), and I was able to go around 325 miles on a tank of gas. I have since moved to Phoenix, where everything is spread out and flat. In the past few weeks I have had a significant reduction in gas mileage. I can now only go 200 miles on a tank of gas. It boils down to about 17mpg. <P>The dealer has checked the car twice, and assures me that it is "operating to specs", but I can't believe that. The loaner S40 that they gave me got excellent gas mileage. I don't know what else to do. I fill it up with Super, don't accelerate rapidly, and don't really drive at high speeds. Anyone have any ideas? I'm curious to know how many miles other S40 owners can go on a tank of gas, or if anyone else is having this problem.<P>Thanks for any help that you can give.
