| Re: DTS owners check in! Perhaps your gas gauge or the on-board info system is incorrect. I am finding that my gas mileage on my 06 DTS is in keeping with the published ratings. I get 16-17 in town (stop and go) and 25 on the hiway as an average. When my gauge gets to "empty", I have used about 15 gallons which means that I have about 3.5 gallons in reserve, which is as it should be. This is my first Caddy but I had three Buick Park Aves and I found this to be consistent, |
