#40 of 60 MPG by donl1 Jan 11, 2008 (7:17 pm)
I have a very hard time believing 24 to 25 mpg in combined driving. Replies to this message: pemnel (Jan 30, 2008 10:00 pm) mark366160 (Feb 18, 2008 6:44 pm) mark366160 (Feb 26, 2008 4:11 pm)

Replying to: donl1 (Jan 11, 2008 7:17 pm) Once again, I made a 400 plus mile trip from the coast to the city, around town running errands, and back to the coast and averaged 25.1 MPG. My Acadia is a 2007 AWD SLT2. although there was only one person in the car, I had 6 cases of books in the back on the way up to the city. After I got home, my wife drove the Acadia to and from work (about 10 miles each way a combination of 50 MPH hiway and 25 tto 35 MPH through 3 small towns) and the milage dropped to 24.2 MPG. There is now 13,000 miles on the car and this is the milage that we have been getting since we bought the car. We do notice an drop in milage when we drive aggressivly or have a full load of passengers. I have in the past owned cars that were "Lemons", maybe this time it was my turn to get the "Diamond".

#42 of 60 2008 SLT1 FWD 1st tank by mark366160 Feb 18, 2008 (6:44 pm)
Replying to: pemnel (Jan 30, 2008 10:00 pm) 1st tank on 2008 SLT1 FWD less than 200 miles on it getting 16.8 mpg doing the 15 mile commute to/from work. Previous car was a 2004 Suburban 2wd, which I could get 15 mpg doing the same commute. Considering it's the first tank and had alot of dealer lot standing on it, and that the mileage showing on the DIC has been slowly increasing the entire time, I figure I''ll get 17-18 doing this...   Also, given I could get 15 on the 'burb, when it was rated for 13 in the city (and spending hours looking at the inst mpg on the thing trying to see how to drive it to get all I could), 1-3 over city average seems reasonable.   Spend 4 years at 15 city 18 hwy, and 17 city anything more than 20 hwy seems wonderful. I guess the people hollering the most are those that went car to this thing, vs goliath to this thing... Replies to this message: mark366160 (Feb 26, 2008 4:11 pm)

Replying to: mark366160 (Feb 18, 2008 6:44 pm) 2nd tank on 2008 SLT1 FWD with about 700 miles on it got 18.8 mpg doing the same 15 mile commute as in previous message. Average MPH was about 26. Mileage was as high as 21 at one point, but once I got to the weekend and started hauling family around to soccer games, grocery stores, etc, it dropped.   Anyway, overall the MPG for this thing is pretty good, especially compared to the Suburban I came from. Haven't had it on the highway for an extended period, so don't know that MPG.   AWD is going to be less. My wife has a 2005 MDX, which is AWD, and the way it works, from 0-15 mph, the thing is in four wheel drive mode. Once you get over 15, it switches to front wheel drive mode. Just having the connection to the rear wheels, whether it's active or not, is going to drain some power, and thus MPG. Where I think the impact is worse is over that first 15 mph. I would think the drag is much more when in 4WD mode, so if you're in alot of stop and go traffic, your constantly in that mode. I would think the AWD Acadia works in a similar fashion. On the highway, the MDX does pretty good, but in alot of stop and go, it's down around 14mpg...
#44 of 60 My 2007's real world milage by cravenfan Mar 29, 2008 (4:31 pm)
Normal driving - 1/2 highway, 1/2 backroads to and from work = 19.5mpg   Highway - 22-24 (24 if I baby it, go the speedlimit, etc.)   Pulling a snowmobile on a trailer = 16.5 in trailer mode   Pulling two snowmobiles on a trailer = 13.5 in trailer mode   My Yukon got about 16.5 all the time. My Acadia has more horsepower than my 99 Yukon did and pulls the sleds better.

Replying to: lukesdaddy (May 12, 2007 4:47 am) We just bought an 08 FWD Acadia and the first tank of gas we got 19.2 mpg! Combination of City/Hwy miles, live in MS so no mountain pulling! I have been very slow to take off and brake and I think that has helped alot too.   Hey, compared to some of these posts, I think that is pretty good!

I bought a 2007 Acadia in June of 2007, and drove to Ohio from Fl. I went up I95 to 77 in South Carolina, and I averaged 72 miles an hour, and got 23 mpg up and back. I have not had any problems with my Acadia, unless you consider all the complimemts I get on my Acadia a problem.
#48 of 60 Acadia MPG by phillybill Apr 29, 2008 (4:54 am)
I am getting 7.2 MPG all city with a soft foot, no compressor, and mostly coasting like a granny. Called the dealer and they took it for a test and said they got 16.6 MPG city. I checked the DIC when I got the car back and notice that they did get 16.6 but had an average speed of 36 MPH. meaning for their city test, they put some highway on it. Called the sales man to complain and he actually told me to go f-- myself. He could care less about the problrems I am having just so long as the sale was made. If he had not bait and switched me, maybe I would have one of the working Acadias instead of this Lemon. As of today, 7.2 MPG, check engine light on twice for cam shaft glitches, dealer had it for 3 days and did nothing to repair because the light went out on its own.
#49 of 60 Pretty impressed w/ the Acadia. by kbacon May 23, 2008 (6:39 pm)
I've got a '08 SLT1 FWD and have had it 3 wks now. Milage has slowly been increasing the more I drive it... about 1100mi now. Averaging about 19mpg lately... started at 17mpg average. Reset the DIC heading home other night (15mi)... started coasting (shift to neutral) as soon as I saw lights turn yellow.. tried not to brake if I didn't have to. Slowly eased on the gas when taking off.. and I managed to average 27.7mpg for that 15 mi trip. This was going 45-55-45-55-45-35-30.. I caught a couple of stop lights.. but made most of them. I was highly impressed!
