We bought our Enclave in Jan 09, it has front wheel drive and used primarily by the wife driving to work and back. 50 miles per day Interstate driving. We've taking it on long 500 miles + trips and have only gotten in the best world 21.5 MPG.
Trip speeds are usually around 70 mph never higher than 75 mph.
Have read reviews where owners are getting 23 to 25 MPG and would like to know the secret to improving mileage.
We love the car!!

I have an '08 Outlook XR FWD. My average for the past week, about half Interstate have city streets but not much stop and go is hanging at 20.3 MPG. But when I can catch some nice flat Interstate without a headwind and ease along at 65-70 I can get 23-24 for awhile. Any hills or headwind and it will drop down to lower than that. I've decided that if I manage the throttle I can get 1-2 MPG more than using the Cruise Control, especially on a stretch with some hills.
 
One time I headed West out of Memphis to take mother home in eastern Arkansas. Had a 25+ MPH headwind. The MPG dropped down to around 16.5-17. On the way back with a tailwind the MPG climbed steadily and IIRC ended up over 20 by the time I got home.
 
I've decided that 5th and 6th are overdrive and double overdrive. If you can keep it easing along in these, great mileage. If you have to drop down to maintain speed you can watch the MPG on the DIC drop pretty quick. Recently on my city street stretch with 40-45 mph speed limit, I have started using the thumb button on the shifter to kind of manage the RPMs. Otherwise once I get up to 40-45 in 5th-6th it kind of seems to lug and wants to downshift easily. I seem to be able to smoothe that out by shifting up and down as needed until 45 or so and sometimes will even downshift at a higher speed on an incline.
 
I still like it and think it gets great mileage for a 7-8 passenger. Wife went to Gulf Coast a couple of weeks ago with her S-I-L in their Yukon and was talking about how much it cost them for gas.

Sep 17, 2010 (4:56 pm)

Just picked up a 2008 Enclave CXL with about 90k kilometres on it. Beautiful car, but the gas mileage is aweful and it seems to lack power. I'm averaging about 12 mpg. I had a Ranier before this and got twice the mileage also out of a six cyl engine. I have already taken it to the dealer and they can't find anything wrong with it. Can anyone suggest a solution to this problem?

Is it AWD or FWD? I had a almost brand new rental Enclave AWD for 2 weeks, and it was bad on gas too. I as averaging about 16l/100km in the city. Highway was about 9.5 and I'm a gentle driver ie. no racing, slow starts etc.FWD should be about 10-20% better on gas. You may find a 2-3 km stretch of flat straight road on a not so windy day. Have the vehicle to display instantaneous gas consumption and travel with the speed of 90-100km/h (55-60mph). You should be getting about 8-9.5 l/ 100km.
If your readings are much higher than that you may try the easy things first. Spark plugs, air filter, check for sticky brakes (hand brake ok?). Is any of the wheels excessively hot after a short drive? Let us know the outcome.

I don't anything is going to help this car.
 
We have owned the Enclave 2WD for 1 year and average 14-16MPG with mixed city and highway driving.
 
Great car, but terrible fuel consumption. It weighs literally a ton!

For all those with Enclaves, check out the Acadia Forum on this site. You won't believe the horror stories. It is the same vehicle.

#22 of 22 Terrible gas mileage by stigs2

Feb 04, 2013 (8:22 pm)

Just wondering if anyone has had any thoughts recently on gas mileage for the enclave. I'm really disappointed as I seem to be getting only about 12 mpg (or 20.5L/100kms) on my 2012 cxl2 awd enclave. I also have 20 inch wheels and do all city driving. Is this normal?
