We have 2009 corolla with 7000 miles on it, we get 30 mpg in suburban driving and only getting 31 mpg on the freeway using the cruise control at 70 mph with the ac on, I was expecting 34-35 mpg on the freeway, is this normal, thanks.

You have to go slower to get better milage. Try holding at 55 mpg. I did that from NY to FL and got 42 mpg. I know its boring to go 55 mpg but so worth it in fuel costs.

Using my own 2009 Corolla gas milage as a guide I would say your city gas milage is exceptional as I only get 26 mpg consistantly in city driving. On the other hand I would say your highway gas milage is low. I can get 39 mpg with air on doing 65-70 mpg.

31 mpg seems low at a steady 70 mph, even with AC on (which is actually more efficient at 70 than having windows open). Why is the Corolla's fuel economy so low at typical freeway speeds? I can easily get low-to-mid-30s mpg at 70 mph on mid-sized cars with much larger engines, and lower EPA numbers. I even got 29 mpg at 70 mph on an Impala with a big V6 on a recent rental. My '04 Elantra with an ancient iron-block 2.0L engine gets mid-30s at 70 mph. It seems to me that the Corolla should do better than 31 mpg at 70, unless there were other factors e.g. strong headwind or mostly up-grade.

You should be able to achieve higher mpg on the freeway. I just drove a one way 500 mile road trip mostly freeway and got 37.42 mpg cruising at 70 with the A/C on in my 09 Corolla with 8.5 k miles on it.

Normal? 31mpg is normal at 70+mph? I disagree, unless a Corolla can't hold a candle to a Civic (which, at least in fuel economy, I think they're quite competitive). After a 300 mile trip at 72 mph Cruise I achieved 37mpg in a 2007 Civic EX Automatic. My girlfriend got 35mpg in my 2.4L Accord Automatic, who was in front of me for the entire trip, cruise set as well.

another possibility for lower mpg

If your concern is for a single reading based on a single re-fueling, consider that fuel pumps vary, sometimes considerably. Depending on how much fuel you pumped, it might not take a large difference in pump calibration to give the appearance that your mpg was off once.
I bring this up because I knew a guy who worked for the state "Bureau of weights & measures" who actually measured the amount of fuel using a large graduated cylinder at the fuel pumps. He said there was considerable variation on both sides and that sometimes the pumps gave less fuel but occasionally were even pumping more than their meters indicated. The lesson I learned in that was that the few pennies savings from one station to another could be meaningless because the variation in volume of the fuel could easily offset any savings of a few pennies. Yet people persist in driving extra miles to a pump that is marked 2 cents cheaper....

It appears that it's low only in this individual anecdotal case. This is more likely a specific driver/vehicle/situational issue. Others have noted values above 40 mpg, but also anecdotal.

I would think so, but the one poster said 31 mpg on the highway was "normal", which is what I was commenting on.
