Sounds like theres something wrong, possibly air intake (glogged air filter), map air flow sensor (located on the tube from air box to fuel injection), or even possibly bad spark plugs. But best deal is to take it to the dealer and request a computer scan and see if there are any codes, and let them know of the problem. Winter time can effect the gas mileage but do not see it effecting it that bad. I have a 2003 corolla and usually get 32 plus no matter, and can pull almost 400 out of a tank of gas in the summer weather, now im gettin roughly 300 + mile per tank, 200 usually on a half tank.
Start with checking over airbox make sure its clear of leaves, acorn stuff from critters, etc. Air box on my corolla isnt the best design, small animals can get into box area. check spark plugs for wear, things you can without paying $75 an hr for a tech to do it, then if nothing works have a computer diagnostic check done by a Toyota dealer, not a back yard mechanic......
 
hope all goes well, im not an ASE Tech, and dont claim to know all, just giving advise that i would follow myself ( for those that might comment).....

I have been getting really bad city MPG like rajivn6 too. I'm getting about 13mpg city and 33+ mpg on hwy.
 
What mechanical or electronic problems could be causing this? or is it just shifting too early at low rpms (less than 2k rpm) causing this low MPG?

My guess is there is a pinhole in your gas tank!
 
Shifting too low, as stated... or shifting too high (3k-3.5k) will take off economy. Of course, it is winter fuel additive season, so that takes off a few MPG as well. Also, if your fuel is 10% ethanol (or, egads, greater), your overall mileage will drop at least 5%.
 
These factors combined, best case, would reduce 32/41 to approx. 24/34... so numbers in the teens/city do seem to indicate an additional problem. Sorry, I'm just an Analyst, not a technician

#173 of 411 Cold weather driving tips by hoopitup2000

For best winter driving mileage
1. DO NOT WARM UP YOUR CAR-Drive gently till your heater is putting out somewhat warm air. All cars runs very rich during warmup. If you are siitting still you are getting "0" MPG. Even if you do warm up your car it should be driven gently beacuse you have only warmed up the engine; the transmission and other moving parts are still cold, They need to be warmed up before normal or aggressive driving or their life will be reduced.
 
2. SHIFT EARLY(MANUAL TRANSMISSION CARS ONLY)-Believe it or not shifting before 2500 RPMS with a heavy foot on the accelerator will provide the best MPG.(ONLY WHILE IN GEAR; NOT WHEN THE CLUTCH IS ENGAGED!!!) This is because you are reducing the engines "pumping losses". Go to the "MOTOR TREND" website and put "TEN TIPS FOR FUEL TEMPEPENCE" in the search box, and see why this seemingly crazy driving procedure really works.
 
I am getting a consistent 34 MPG using these techniques in winter driving with many short trips in mixed city and highway driving.
 
In the summer my mileage "averages" in the upper 30's to low 40's using the same technique with a 50/50 mix of city and highway driving. Summertime highway driving can yield numbers in the mid 40's.(Over 70 MPH driving will start to reduce these numbers). Even driving in mountainous areas can provide low 40's if the RPM'S are kept as low as possible without lugging the engine.

I have a 98 with 250k miles and been consistently getting 28/29mpg mixed city/hway I thought I was doing ok but after reading all these posts, I guess not, it could be the miles or the fact I have no overdrive tranny. anyone out there with a3 speed rolla?

I am the owner of Toyota Corolla S 2006 5MT
 
In the winter I get around 36-38 MPG (combined, depends how cold the weather).
In the summer I am constantly getting 44MPG combined.
 
I usually drive 80% of the time on highway. This summer I will try to get into 48MPG mark (I know how...).

#176 of 411 reserve fuel tank by dkeanie

Mar 20, 2008 (12:04 pm)

does anyone know how many miles you can travel when the fuel warning light comes on? I have only done 239 miles town driving and the light flashed on then went off. This is from a full tank too !! I thought I would get better mpg than this. I have a 1995 Corolla 1.6 efi.

I do not know about Corolla '95. I do usually my refueling around every 500 miles. But majority of my milage are done in highway.
One time I got 50/50 driving (city/higway), I was forced to refuel at 400-420miles.
 
Again, everything is depends how you drive and where you live. If you live in Alaska, 240 miles in city is normal. In winter I am not getting more than 400 miles per tank.
