Well, I don't get the mileage some of you do, but I finally got a 600 mile tank. I had to go about 22 miles blinking and put 11.6 gallons back in, but she made it! The final rundown: 611 Miles, 11.614 Gallons, 52.6 MPG. Actually a bit higher than displayed (50.6). I can't imagine that I could have gotten any more gas in the tank, it was coming out almost to the point of running to the ground after several burps. Thanks for all of your tips. The easy driving in the city is what helps. As a salesman, when I am driving on the highway I set the cruise to 72 and let it roll as I am on the phone a lot. Regards, Larry
