Replying to: chezky (Dec 25, 2007 2:19 am) we only get 8.2 miles per gallon city NORMAL driving. my armada got b/w 10-11 mpg. just got it about a month ago have to fill it up every 5-6 days and summmer were hardly driving like the schoolyear . the dealer said maybe the computer needs to be adjusted, is the computer eating my gas? also when i accelerate the car kind of kicks like its trying to catch up to speed.

Drove to San Antonio and back from Houston over Christmas. 2008 Acadia had 22mpg going to SA and 28 coming back. Wind power rules!

Replying to: acadiaregret (Aug 03, 2009 10:49 am) If you find any solutions let me know GMC sure doesn't have any. We have never achieved anything better the 12.5-13.5 in town with very little mix of highway and 17-19 on the road. Makes me regret trading the 99 Tahoe that did better and had much more horse power and performance. At least I knew I was giving up fuel economy for performace with the Acadia I get neither. All GMC could offer was keeping the Nitogen pressure (which is a joke as far as I can tell) in the tires at 38-40 and using 100% gas with no ethanol. I think this results in about 1 mile per gallon difference. There where rumurs that GMC would come out with a better automatic shifting algorithm for the transmission, but I have never seen it.
#60 of 60 My experience by loach Aug 03, 2009 (1:23 pm)
Now that my '08 AWD Acadia is broken in, we've been getting mostly 13-14 MPG city and 20-24 MPG highway depending on conditions. We've never come close to getting the 16 MPG city EPA rating, but easily beat the 22 MPG highway rating if the conditions are favorable.   I consider these numbers to be well within reasonable tolerances. The Acadia is a bit of a pig in stop and go traffic, but really shines on the highway for a vehicle this size.
