I got 32 MPG!

Chat about all things Bonneville (and related cars). Off-topic stuff should be in the lounge, and all mechanical problems should be posted in the proper forum.

My 2002 SLE seems to average 26.5 according to the DIC, but manually calculated comes out closer to 25.5 or so.

This is 50/50 city/highway. I'm taking it on a roadtrip to Missouri in a few weeks and can't wait to see what I get. The DIC shows me some pretty good instantaneous numbers on the highway.

btw. Someone above said their DIC was only 0.2 off ..... is this typical? What could cause high readings?

On our way back from Wisconsin, going 70-75 my '05 SLE got right about 32, Eric's I think was a hair better with his mods. Currently, with I would say 30% city driving and 70% highway driving I am getting around 27 MPG....hoping it goes up a bit with the recent work / maintenance.

The best I ever got was 36.1 MPG in the 96, 31 in the 99. And the Envoy has somehow managed to pull 24.3 Going to Milwaukee; on more than one occasion.
