#5 of 14 Real World MPG for Enclave by lwolf99 Jul 16, 2007 (2:18 am)
I have had my 08 Buick Enclave CXL AWD for 2 weeks now. I am averaging 14.7 MPG in mixed city and highway driving in Pittsburgh PA (lots of hills). This was calculated by miles driven divided by two full tank fulls of gas. But the computer does also report almost the exact same figure.

We've had our CXL FWD for 2 weeks now. Most of the driving has been commuting back & forth to work with a few highway trips (330 miles on the odometer) Living in Florida hills are not something we have to deal with, yet we're only getting 12.6 mpg This is the biggest dissapointment with the Enclave. Any ideas on how to improve this? We traded in an '02 Seville with the Northstar V8 & it got much higher MPGs.

Replying to: billdoug (Sep 24, 2007 11:42 am) What's your driving style like? I'm here in Florida too and I have an SUV (not this one....yet) and how you take off from stops and how you punch it to pass/accelerate make all the difference in something that heavy.   I hit the gas pretty hard merging onto the freeway here in central Florida with the speed at which traffic travels here, so of course, I worsen my mileage. Just a thought. Replies to this message: billdoug (Sep 24, 2007 2:06 pm) jbjtkbw00 (Sep 25, 2007 6:47 am)

Replying to: jbjtkbw00 (Sep 24, 2007 1:08 pm) You're right,driving style can make a huge difference. We don't put the pedal to the medal when taking off/merging (majority of driving is surface streets) Have found that when your cruising along at say 60 & want to pass someone you HAVE to punch it to get it to get up & go.   Replies to this message: jbjtkbw00 (Sep 25, 2007 6:47 am)

Replying to: billdoug (Sep 24, 2007 2:06 pm) Hence why I'm waiting on the Super version. I know the gas mileage still won't be fantastic, but you won't need as much pedal to get going on our highways.

2008 Enclave AWD   First tank average in city driving was 15.5 mpg   Second tank average in city driving is currently at 17 mpg   Ran a 3 hour trip on interstate with speeds from 70 to 79 mph run average was 23.5 mpg   If this holds up or gets slightly better I will be very pleased.

Replying to: billdoug (Sep 24, 2007 11:42 am) I have 2k miles on my AWD CXL 08 and getting about 20 to 23 on mine. 70%H 30%C. I actually just learned how to get more MPG by watching the news a few days ago. Go to (cleanmpg.com) and try some of their suggestions, it did help me out quite a bit and I think you become a better and safer driver as well. I use to get just about 14 to 15 MPG before seeing this news on ABC or CBS I don't remember. I live in Colorado 50/50 on Hills, but with your CXL FWD you should even get a few more MPG then mine. Hope this help you.
#12 of 14 sunroof wind deflector rattles when closed by paulh5 Jul 01, 2008 (1:09 pm)
The wind deflector rattles when the sunroof is closed. The wind deflector is a piece of plastic that springs up when the sunroof is opened. When the sunroof is closed this plastic is vibrating when I drive. I can push my fingers up into sunroof cavity, and press down on the wind deflector - and the sound goes away. I'm thinking of placing some foam weather stripping in there. Has anyone else had this problem?   So far no water leaks, though:)
#13 of 14 Mileage by fisherman59 Aug 27, 2009 (1:38 pm)
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!! Replies to this message: wlbrown9 (Aug 28, 2009 12:46 pm)

Replying to: fisherman59 (Aug 27, 2009 1:38 pm) 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.   Bill
