Toyota Corolla Real World MPG

  • Hi All,

    It would be freally great if anybody could help me out on this issue. I have a 2006 Corolla LE with 41000 Miles in it. Am getting 10 MPG in city driving. And i tested in the freeway and am getting 32 MPG. What could be tthe reason? I bought this car from a dealer as a used one.

    Hope i can hear a solution soon...

    Thanks
  • 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! :sick:

    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 :)
  • Thanks for your time and valuable advise.I will definitely go and check with the dealer once again .

    Have a nice time!!!
  • 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...). :)

    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.

    For a Toyota Corolla with automatic and cruise, is driving 55 mph the most fuel-efficient highway speed, or is it 60 mph? I know it's either?

    I just picked up a 2009 Corolla S on Friday and I'm EXTREMELY happy so far!

    Today was the first day I drove it to work (80 miles about 90% of that is highway). Just before I exited the highway I had an average of 44.1 MPG! By the time I exited and pulled into the parking lot I was at 43.3 MPG!

    I haven't changed my driving habits at all as of yet - I rarely go below 70mph on the highway.

    I just hope this fuel economy keeps up as the car starts to break in!

    I do not have an exact answer for you but I can say that you have at least a gallon left in the tank when the light comes on. The owner's manual does not say. It would be safe to drive 25-30 miles. This occurs when the light stays on. It might go on and off before it stays lit. Acceleration or braking or inclines or declines make it come on temporarily.

    Just curious as an accomplished high mpg-er, myself....tips for this 48 mpg experience?? :)
    Thanks,Don Gillespie

    That does sound like you are getting good mpg. I am driving a 1.6 efi and am only getting 31.4 mpg which i don't think is very good. My Corolla is a 95 N.

    First time vistor to the site. Just wanted to comment that I average 36-37.9 mpg on my 99 automatic 3 speed with overdrive. All my miles are I85 and I285 Atlanta roads driving at speeds that average 80 miles per hour. Thus far, I have been quite satisfied. With the price of gas though, I have been considering the toyota prius to bump the mpg to 45 or higher.

    ps- I have a 12.9 gallon tank and usually refill once I hit 420-450 mile to the tank. Normally try to get an extra 50-100 miles once the low light comes on.

    I just bought a 06 corolla LE (auto) with 2700 miles on it. I refueled just today and I did the math to realize that I only got 200 miles with almost 8.7 gallons. That comes out to be around 22.3mpg, which is waaaaaaaaay lower that what i expected. I am driving in the city, trying to minimize the brake pressing. Only reason I bought this car is for the great gas mileage that everyone has been talking about, but I'm not getting it =/. Can somebody help me out?

    A 2006 model with only 2700 miles?

    Where did you get such a low mileage car?
  • mcdawggmcdawgg Posts: 1,667
    Is this the first refuel that you did? Reason I ask is you don't know if the tank was full when you bought it, or how many miles it had been driven on this first tank before you started recording.

    Also:

    1. You can't base MPG on just one tank.
    2. All makes and models have people complaining about MPG, but the driver and the conditions are HUGE variables here. A problem with a car that affects MPG is pretty rare.
    3. The Corolla will deliver excellent MPG (best in class) if you compare equal conditions (driver and traffic, etc) to other cars.

    Refuel at the same station, same pump, and use the trip odometers to track total miles driven until you refuel again. Refuel only until it shuts off - don't top off.

    Try a few more tanks and let us know. Also note the driving conditions, speeds, how long stopped, etc.

    >"explain how pressing the brake burns more gas"

    Obviously pressing the brake is necessary.

    How and when we use the brake will affect mileage. If we never had to use the brakes, we would get considerably better mileage. It would be like driving on the highway all the time.

    Here are a couple of extremes to ponder.

    Up ahead is a stop sign. If we let off the gas at a point that we will coast up the the sign and use the brake very little, there was an amount of road traveled using only the amount of gas necessary to idle the engine. If we stayed on the throttle until almost there, we burned unnessary fuel over that distance. If there are a couple of cars waiting their turn, when we get there, we may start-stop a couple of times before it is our turn to go. If we had "coasted" to the sign, possibly 1 or all the cars would have been gone and we would only have to stop and start once.

    The traffic light ahead is red. There are several cars sitting. Slow down back here.
    Let the car coast toward them. Hopefully by the time you get there they will be moving and you won't have to stop at all. OR we can keep accelerating, then slide up behind the last car while the light is still red. Wasted gas getting there, more wasted idling and waiting on the light to change, and more wasted accelerating the car from a stopped condition.

    Tail gateing burns a lot of unnessary fuel. And doesn't get us there a bit faster. Actually someone tail gateing me will get there slower. I tend to slowly reduce speed to the posted speed limit when someone is on my bumper. If there is going to be a "Crash", I prefer it to take place at a lower speed. :)

    Running up behind someone and hitting the brakes constantly, will burn a lot of unnessary fuel. Gas-brake, gas-brake.....! Any time the car accelerates, it uses more fuel than when "cruising" the same terrain. Stay back a few car lengths and enjoy the "cruise". This saves fuel, brakes, and tires.

    So yes, using the brakes does cause extra fuel to be burned. Every time we use the brake we either just used extra fuel and/or we will use extra, getting the car back up to speed. :)
