Using the trip meter in the 2009, I was getting 43+ on my 60 miles per day commute to work averaged over 2000 miles of driving. I didn't check with actual fill up's, but I know it was good. I am a very conservative driver though and loved to see how high I could get it. That was at 65 MPH mostly.

I don't understand your question, could you expand or elaborate?

Mpg for 2009 for Corolla LE 27-35
Mpg for 2010 26-34
I was wondering why. I did notice that they changed the tire for 2010 from good years to bridgestones

I think I read something in ToyotaNation about the Engine Control computer programming being changed, and that changed the fuel mpg. Maybe someone here can explain?

I have a 2009 corolla purchased new 10 months ago, I travel about 45 mi day and frequently use cruise control, and get 39 mpg. Not many street lights to stop at though. I must say that if i don't use cruise control the numbers are closer to 34 or 35 mpg, I get much more smooth ride up hills if i click into cruise, seems to hold at the speed instead of a constant up / down shift. If i travel on flat freeways on cruise set at 68 mph I get 60 + mpg it is great! I have a LE 4 cl. automatic

My 2010 Corolla LE (1.8 automatic) has averaged 37.7 mpg overall for its first 2000 miles. That is based on actual gallons purchased and actual miles driven, not the indicator on the instrument panel. Much of my driving is on the highway (at 65-70 mph), but I've also done quite a bit in town, and on secondary roads at 35-45 mph. Compared to the "clunker" I traded in (a minivan rated at 18 mpg combined) this is a fantastic improvement.

the 2009 corolla had the TSB on a possible excessive use of oil under certain conditions. toyota's answer for this was to reflash the ECU. it has been theorized over at toyotanation that the only way this would help with the oil consumption problem is by detuning the engine, resulting in reduced hp and/or reduced mpg.
 
since all the 2010's had the updated ecu programming already, some of us believe that is connected to the city and highway mpg going down by 1 mpg.
 
however, the manual transmission models in the base and s versions of the 2010 did not lose anything from their '09 rating, remaining at 26 city and 35 highway, so perhaps the manual transmissions werent afflicted w/ the oil consumption problem in the first place. i know one member got a response from toyota that they tweaked the testing to better comply with the epa requirements, thus resulting in the drop on the automatic tranny. it remains a mystery for now.
 
at any rate, i never had an oil consumption issue. i have the 5 speed manual and easily get 40+ mpg (calculated) on mostly suburban and hwy driving without making too much effort.
 
i will say that the computer mpg readout is fairly accurate compared to many other economy cars out there. my computer readout is consistently within .5-2 mpg off from my actual calculated mileage.
