Time for a swap, buddy! My SC3800 does that with my foot buried in it.

Make sure the car is PROPERLY tuned. You should be up close to 30 mpg unless your foot is buried to the floor boards all the time you drive.

Also the people getting the really good mileage with the Duke are using manual transmissions. Also make sure that your TCC is working correctly... does there feel like there is a fourth gear that kicks in when you stop accelerating?

I think the correct term is "in-flight refueling" with your foot in it. It's 5-6 MPG at WOT.

When new and the speed limit was 55mph, I'd get 36 mpg with my 87GT using 5 speed getrag on the highway. At 100K mile it can get 30-33 mpg on the highway at 70mph.

My 88 4 cyl auto never got better than 28 mpg on the highway. Some people just macially get 30+ mpg on their dukes, I don't know why I never did.

Gas mileage just like performance varies even on identically equipped brand new cars. The numbers on the window sticker are based upon test model(s) and represent an average expected. Some will be higher some lower. Of course as someone stated earlier condition of the vehicle has a lot to do with it as well. I had an 84 with an Iron Duke and when I first bought it it got like 19 MPG. After I did a full tune up, and replaced things like the EGR valve and the PCV which the guy had rigged up really wierd (that's a whole story in and of itself), It bumped up to average to about 24-25 MPG dependant upon the grade of fuel I was running. I know the Duke is capable of better though. My first car was a 1986 Oldsmobile Cutlass Ciera with the good ol' Duke in it and that big heavy boat of a car got 26-28 MPG.
