I know this is an Acadia forum, but the motors are the same, as are the transmissions, so - let's compare! My Outlook keeps getting better mileage as it breaks in. Travelling with two people and luggage for a weekend(approx. 400lbs total), A/C off(23C/73F), at the speed limit(100km/63mph), -(all #'s from the DIC), tires at 35psi(240kp), the mileage read 30.7mpg(7.6L/100km)!!!! The terrain was fairly flat, but, even on slight hills, it did not change much.It stayed that way for about 5 miles(8km)until traffic got heavy(stop-and-go). I now have 10000+km(6200+miles) on the Outlook, and as it ages, the mileage improves. How about you guys out there? Similar results? ???

logbit - I only hope to achieve those numbers but I can't seem to take a vacation without seven suitcases, two kids, two strollers, wife who breathes A/C and food/snacks to feed a petting zoo. That being said, I'll never achieve those figures.
However, as said in many threads - you can't use the DIC. It's as wrong as two boys screwin'. My Expedition gets better than the window sticker too (13/17) since I normally average 19.6 mph on freeway trips even with the above said load. However, I installed a K&N, use good fuel (not 7-eleven crap) and always keep it clean (bug juice weighs down a vehicle my dad use to always say). I'm one of those dedicated car cleaners that enjoy washing my own vehicles on the weekends (I'll never use a car wash place).
Hope you duplicate those numbers and make us all see the light.

Yup - I know, but the numbers are going the right way - I started at around 19.6mpg when I picked up the car. Now it is 30.7mpg. Even if the accuracy of the DIC is suspect, the direction is just fine with me! The predictions of better mileage as the motor/transmission goes through the break-in period are coming true. Am I the only one with the same experience? :eek:

Now granted I only have 500 miles on my Acadia...but I'm averaging 13.2 MPG...and I'm not being a leadfoot. I'm also being gentle on the gas peddle when starting from a complete stop. I'm betting that the MPG will go up once I break the engine in a bit.

My personal best was on a beach trip, 210 miles one way, nearly all interstate with cruise set at 70 and a/c on the entire way, two people, two large dogs and a modest amount of luggage ... 25.7 mpg. My daily commute is averaging around 22, twenty miles one way, somewhat hilly, about a third urban/suburban and the rest wide open two lane. My mileage around town isn't so great, it's a real effort to get the EPA rating, typically 16.5 - 17 mpg. My mileage has improved since new. This is all via the DIC, and I haven't taken the time to determine how accurate it is.

On our summer trip, 2,700 miles, I measured it between two fillups on driving days and got just above 26mpg both times, so going north or south through Illinois didn't seem to matter. Overall, the DIC measured 24mpg, which I think was pretty much right.

On non-trip, everyday to the store and stuff, and my wife driving my girl back and forth to school, she is getting 20-21mpg-- we don't have much stop and go though, and being on the outer edge of the suburbs, we get some highway driving in there too. I couldn't be more thrilled, as in her Jeep GC V8 she was getting 13-14 in the city (about 23 highway) on mid-grade gas, and the Acadia is on 87-standard gas.

Slowly, but surely, mine is starting to creep up. Last fill up, I got mid 13's city. Today, all city driving was 14.4! (The first several fill-ups were in the 12's.) My DIC was within 1/2 gallon today, too. Fluke or real improvement, I'm not sure. But, I'm becoming optimistic. I have 2700 miles.

Good on you! Just wait 'til you hit the 30mpg level! :cheers: :blob:

don't get too excited until you check your dic against actual.

out of my last 10 fill-ups, the dic has shown less fuel used than actual on 9 of the fill-ups (the only one that went the other way was 0.20 gallons more than actual), which means the average economy calculation is inflated. just looking at the 9 where the dic shows less, the average that it is off per fill-up is 1.4 gallons. the difference is trending higher over the last few months as well (the last fill-up was 1.7 gallons more than the dic showed).

might want to do the math with actual numbers before you start talking about 30 mpg. i'd like to get that, but i'm not sure that's possible under normal circumstances.

Already done! On a 4000km trip, we averaged(highway) 9.5L/100km(actual fill-ups/mileage). The sticker says that 8.4L/100km is 34mpg. I guestimate that is just between 26-29mpg. It has improved since then. All the figuring aside, I just want to say that the Outlook is performing well, getting better, and is a pleasure to drive!! Some small glitches have been fixed by the dealership. I don't dwell on negatives - they tend to spoil the experience :)

My Saturn Vue was like that. Both of them were actually. Started out with pretty cruddy gas mileage that mproved over time... though it was hardly ever what I would call acceptable for an SUV its size. My Acadia still beats out both of the Vues I've owned ('03 and '06) with respect to mpg and it's only getting 19mpg around town and 24.5mpg at best highway... which I'm actually okay with.

cegledi,
What was the K&N filter and did you have to reset the computer? I was looking to do it, but the air filter set up looks like it would be a pain in the a $$. Also, is it an air kit or filter only.

Silent - it was a K&M Fitler (not the air kit) and it was about $50 (available at most auto part stores). Extremely easy to install and instantly felt a difference in driving (not dramatic but noticeable). More HP as well as acceptable MPG for a large rig. No computer to reset because it just replaces your standard air filter. I've saved at least that $50 already by not having to change out my air filter at service intervals. I put one in my Passat too and love it there too. I will get one for the Acadia just because I believe in: free-breathing car = efficiency.

check your math: 9.5L = 2.51 gallons (G = L x .26417) and 100K = 62 miles

62 / 2.51 = 24.7

62 / 2.51 = 24.7
But Canadian gallons are about 20% bigger than US gallons, so it should be about 29.6 mpg. (Assuming they are Canucks since they are talking metric)

i don't think the post said anything about "canadian" gallons; everything was in liters and kilometers. i just converted it to the same numbers that i go by for comparison.

What is a Canadian gallon and how is it bigger than a US gallon? <img src="http://www.laguns.net/iB_html/non-cgi/emoticons/huh.gif">

Don't they use liters in Canada?

1 US gallon = 3.7854118 liter
1 mile = 1.609344 kilometer

I come up with the same calculations as texas123 did.

24.7mpg is probably the best my Acadia has ever seen on a road trip and that was with me adhering to the posted speed limits and not making up my own as I went along. ;)
