#167 of 202 2011 Equinox - poor gas mileage
Apr 26, 2012 (4:50 pm)
I have a 2011 FWD 4 cyl Equinox LT and am only getting 22.4 mpg mixed city & highway. On a long trip, I'm lucky to get 24.5 mpg. The only response I get from the dealer and GM customer service is "The car needs to break in". I have 14,000 miles on it now and still getting the same lousy mileage. I had a 2010 FWD 4cyl Equinox LT that got great gas mileage - 27 mixed city & highway and 31 on trips. Had to trade it out due to a faulty computer. I just can't believe that GM made that many changes in 1 model year that the mpg would change that much. I certainly haven't changed my driving habits so it has to be something they did in their model change. I'm very disappoointed in GM and feel that they have mislead the public when they say the Equinox gets great gas mileage and 600 miles between fillups. I get mad every time I see that commercial. I have driven GM products for over 35 years but I doubt that I will ever buy another GM product unless the company can come up with a solution to the mpg problem.

We just passed 10k miles on our 11 4WD Nox. We do live in a hilly area and we do little highway driving. I am the slowest turtle coming away when the light changes and I coast whenever possible.
However, day to day I cannot get the gas to 20 mpg, let alone 22, 24.5, etc. Even at 60 mph on a flat highway across a lake, it tops out at instantaneous readout of about 24.5.
I've had the reflash etc. done (but that was mostly cos the car kept stalling in mid-road), and it hasn't helped worth a damn.
I come here to read with wonder the tales of people getting 30 or so on long trips. But frankly, it really rankles when other people come on here saying that owners like me just have unrealistic expectations.
A car that is advertised as the Nox was should not be getting an average of about 19.
Then again, I have to ask myself just why am I complaining? It got 17 when I first bought it. Thank goodness it's broken in now! (sarcasm alert)

If your vehicle is still under the total warranty period, I would take it into a good dealer and have them check out your engine electronics and drive train. There should be no reason that these cars cannot acheive the 25MPG combined estimates that are advertised. I have hit 30/32 mpg on the driver info center average on long trips at moderate speeds with the econ on but never consistently and my GMC now has 23000 miles and Equinox has 18000 miles, mid 20's are realistic and probably the best you can expect under average driving conditions. Good luck.

Thanks for that information. My car is still under warranty so I will take it to the dealer and have them check out the electronics and drivetrain. I would love to reach 31 mpg on long trips again.

I understand how you feel , our equinox awd only acheived 32 mpg ( cdn gals are 1/3 bigger than us ) GM advertised getting 41 , like hell !!! instaneous readout useless ,fluctuates wildly , anyway installed a performance chip ( possible gains up to + 6 mpg ) and last long run got 37+ still short but an improvement . We drive very economicaly and find that GM simply lied . and sevice reps only concerned with GM relations not the customer, theres not many satisfied owners & lots like us who drive carefully to obtain good mileage and fail to do so.
PS we have 20000k on our 2011

The EPA has a test for gas milage. Its really a flawed way of telling what a car should get on highway or city. Till this changes you will never get what you want . But I agee with you, till car makers adjust to real world gas mpg , you will have unhappy customers
#173 of 202 2012 Equinox 2LT 4 cyl, fwd - Fuel Efficiency
May 08, 2012 (9:47 am)
First report on this 2 month old vehicle with 3,000 miles. Not a day goes by without me, or my wife saying that we love this car.
I have been watching forum posts on this vehicle for over 3 years and at times wondered if I would be happy with the fuel economy, which was a primary reason for choosing the 4 cyl, non all wheel drive version. I live in Western Pennsylvania which is very hilly, but not mountainous. The 4 cyl has been more than adequate on performance in my opinion. The 6 speed gearing takes care of any steep hills.
I have had my Nox for 2 months now and have had 7 fill ups:
Tank 1, 25.6 mpg DIC, 25.1 actual, avg speed 32.5 mph (city & hwy)
Tank 2, 24.0 mpg DIC, 22.2 actual, avg speed 27.5 mph (city & hwy)
Tank 3, 26.1 mpg DIC, 25.2 actual, avg speed 31.6 mph (city & hwy)
Tank 4, 25.4 mpg DIC, 24.2 actual, avg speed 32.0 mph (city & hwy)
Tank 5, 24.2 mpg DIC, 23.4 actual, avg speed 28.5 mph (city & hwy)
Tank 6, 25.3 mpg DIC, 23.4 actual, avg speed 29.9 mph (city & hwy)
Tank 7, 31.3 mpg DIC, 32.7 actual, avg speed 51.7 mph (trip)
What this shows is that my combined mileage for city & hwy (tanks 1 thru 6) is 25.1 mpg DIC and 23.9 mpg calculated, or 5% less than what the DIC states. My average speed was 30.3 mph, which shows that there is good bit of highway driving mixed in with the city driving. Too difficult to keep track of the exact percentage of each.
My last fill up was after a 354 mile trip from Pittsburgh to Ohio, in which I got 29.3 mpg (DIC) going out and improved to 31.3 (DIC) coming back without resetting. That meant that I actually did better than 31.3 on the trip back as it pulled up the 29.3 average to 31.3.
Going out, there were 4 people in the Nox, no AC, traveling 60-70 mph, on interstate (70%) roads and slower on 2 lane (30%) roads with an occasional town, a few stop lights, and some 35 mph zones.
Coming back, with 4 people, I did more interstate (80%) driving, used the AC, but kept my speed at 55-60 mph. I watched as my trip average continued to climb to 31.3, knowing that I was getting higher if it was continuing to climb. My big surprise was when I filled up and instead of a 5% DIC overstatement error, it calculated out to 32.7 mpg and a 4.5% understatement on the DIC. I did the calculation at the pump and was so surprised that I went back and tried to put more gas into the tank, thinking that it was not full. The nozzle clicked off each time I squeezed it, telling me "hey the tank is full." I did manage to put .5 gallons more into the tank, but it was over full and topped off more than any of my previous fill ups. I will have to see if the DIC understates on my next trip. I wonder if it is due to some software formula used by the DIC. Anyone out there (those of you who check DIC error) have a similar experience where the error flips from 5% overestimated to 4% underestimated on a trip?
So, I averaged over 32 mpg with the AC on and with a full load people. The elevation of both ends of the trip were very close, so there wasn’t an overall elevation factor involved. There was no noticeable wind in either direction that would account for a meaningful impact on economy. The major difference was that I drove 10 mph slower on the interstate on the return trip. My tire pressure was 38 to 39 psi, temperature was 50 degrees going out and 75 returning. I also checked my odometer calibration the first week that I had the car and it was right on.
So, needless to say, I was very pleased knowing that at times I averaged a good bit over 32 mpg, maybe 34 considering all the times that I had stopped for lights, driven at 70 mph and went through reduced speed zones on the two lane roads.
The EPA test for hwy mileage is an indoor test that does not involve stops, hills, wind, cold temperatures, using the A/C or exceeding 60 mph. Probably, the EPA applies a correction factor for that.
I would think that the EPA obtains a sample vehicle from the manufacturer, tests it and then gives a mpg number for that vehicle. That is the number that the manufacturer then publicizes. So, by my experience, one cannot say that GM is misrepresenting on the 32 mpg claim, only that one may have a Equinox with a problem, or a driver that fails to understand all the factors and the influence that each has on mileage.
I would buy another Equinox without any hesitation. Hope this helps those that are concerned about mileage.

H i your comments are very interesting , you seem to have bought one of the few Noxs that seem to achieve what GM claim, but then you have the fwd version ours and many others who have the awd version have economy issues, other then that we do like our vehicle, just upset with fuel economy, and we have done very careful checks on hwy use only ( not interested in city use ) just what we can get from point A-B hwy not close to GM claims.

'Coming back, with 4 people, I did more interstate (80%) driving, used the AC, but kept my speed at 55-60 mph.'
I think you would find thats the magic speed for getting the best milage on the highway. If you happen the match the tach numbers you see at 55-60 at lower speeds it should also do well.
#176 of 202 Mileage has stayed about as expected
May 22, 2012 (5:57 am)
Since my last post I went on 3K mile trip thru Pa, Oh, In & Wis. Most of my driving was interstate, average speed 67 MPH. Overall MPG was 30.6 DIC ,near 30 using the paper method.
Shortly after the trip had one short trip where I drove 350 miles hitting about 55 MPH. Mileage was near 32 MPG.
This is on a 2012 FWD 4cyl. LS now with 5K miles logged.
Fuel used was in most cases with ethanol at the assumed 10% level.
