Toyota Corolla Real World MPG

    I will soon be replacing the original Goodyear Integra tires on my 05 Corolla. Can anyone suggest which replacement tires would get the highest mileage for me? Good tread wear is also a consideration. Thanks in advance, Mike

    I replaced my Integras on my 2001 Corolla with Goodyear Allegra tires made exclusively for Sam's Club. These tires have excellent treadwear and traction at a very good price. I would highly recommend them to anyone.

    I was never impressed with the Integra series tires in wet driving conditions, so I replaced the tires on my 04 with Goodyear Assurance Tripletread tires....made night and day difference. As far as I know, there wasn't any MPG change....

    4.9L/100km = 48.2 mpg (US)
    Speed: 55mph to 70 mph
    Stop every 60 miles or so.

    Interesting article!
  • Hey guys, what am I doing wrong?

    2005 Toyota Corolla 4 cyl
    K&N Air Filter
    Recent Oil/filter change, trans fluid

    Stop & Go traffic in Los Angeles
    A/C on 50-70% of the time
    a little aggressive driving.

    22 MPG average.... on my 13.2 US Gal tank, I've not broken 300 miles yet. Can A/C and aggressive driving do THAT much of a difference? I read about 27 MPG and cry, I read about 35 and up and I wail.

    Help! :cry:

    >Ok, what am I doing wrong?...... Can A/C and aggressive driving do THAT much of a difference?


    Keeping in mind that really heavy traffic and lots of idling and moving the car, from stop, burns a lot of fuel. Here are some tips that may help. Don't get upset with me. Just read and take what you need and leave the rest.

    With an automatic, anytime you press the throttle hard enough, so that the RPM gets much above 2200 before the tranny shifts to the next gear, you are wasting fuel.

    Every time you touch the brake, you just wasted gas. The more brake you need, the more gas you wasted. Let me explain that!

    There is a stop sign ahead. You can let off the gas back here and coast up to it, or you can stay on the gas until the last minute and brake hard. If you choose the second option, you burned unnessary fuel, used more of the brake lining, and wore extra off the tires. You still had to stop!

    If there were cars waiting at the sign and you coasted, you may have had to stop only once, as they may be gone by the time you get there.. If you rush to it, you may start and stop several times before you get through it. Same holds true for traffic lights. Rushing to a "RED" light, so you can stop, waste a lot of fuel, brakes and tires tread. Take your foot off the throttle back here and the light may be green when you get there.

    If you think about it, the reason a car gets better mileage on the road than around town is because, on the road, the brakes are not used as often and constantly getting the car up to speed is much less.

    Tailgating, so that you are constantly accelerating and braking, waste an enormous amount of fuel and you aren't getting there any faster than if you back off a few car lengths and drive with a steady foot. This will also greatly reduce the possibility of a rear end collision. The car in front suddenly brakes hard and you either hit them or manage to stop, but the car tailgating you didn't have time and plowed into you. If you had been farther back you may not have had to brake that hard and the car behind you would have had to deal with a slow down rather than a panic stop.

    On the road, a steady foot at lower speeds requires the car to push less air and the engine is turning less RPM and uses considerably less fuel than trying to accelerate around everything on the road.

    While it may be true that the K&N filters may "Add" a few horse power, it is at near "Red Line". If that is where you drive all the time, don't expect much in the way of mileage.

    Consider this. The mfg are squeezing all the mileage they can out of these "Economy" engines. They also consider longevity of the engines. You can believe that if a free breathing air filter/intake would add anything to both, they would use it. They tune the engines to the type of filter/intake they establish as best for their engines.

    Spend an evening reading the various post on these forums. You will find that people with heavy feet burn more fuel. PERIOD! I personally don't understand why someone buys an "Economy" car and does everything they can to burn excessive fuel. To me, "Bragging Rights" goes to the person that got 40 + MPG on that road trip. Not to the person that got poor mileage but passed everything they could. But that is just me. :)

    My 2000 Corolla (37,000 miles) started to decrease in mpg down to 22 or 23 mpg in stop and go driving, although my driving habits remained consistent. Then my "check engine light" came on, and I took it to my mechanic. He went over the innards of my car and told me that I needed a new oxygen sensor, which I told him to replace. After the repair was complete, my mileage increased to 26.5 - 27 mpg. might want to check your oxygen sensor. It can make a difference.
  • arb, that's a great tip on the o2 sensor. And Kip, no worries on 'getting mad', as that is EXACTLY what I asked for. Thank you both very, very much!

    In April I started using a new fuel additive in my 2003 Toyota Corolla with 78K miles. I was skeptical at first but was given a free trial sample and with gas locally now over $4.00/gallon, I decided I had nothing to lose by trying it. My baseline MPG in a combination of city and freeway driving (65%/35%) was 25MPG (estabished over three tanks). I started using the additive called Engine Boost 2.0. I have since put seven "treated" tanks through the car and with one tank saw a 29% increase in gas mileage! My average increase over baseline per tank for the seven tanks has been +19%. That is with using the air-con non-stop the last three tanks. With my 13.2 gallon tank and with gas at $4.00/gallon, that means I am getting the equivalent of an additional 2.5 gallons per tank and saving about $10 everytime I fill up. I only add 1/8 of an ounce to 13 gallons and it costs me about $1.50 per tank to save $10! I've never seen an investment with a better return. I also find I have more horsepower and it seems the emissions are cleaner. It's great and I've started using it religiously in my other four cars - Tahoe, Miata, Accent and Mazda3 - with similar results with each car, saving from 6-15% over baseline. That is with the air-con on so I'm sure the actual results will be even better when the weather cools down. My college kids commute to school and our family is saving about $250 a month on gas using this stuff. Has anyone else tried it? (sorry, this sounds a bit like an infomercial but this stuff really works!)

    Interesting post!

    Where can Engine Boost 2.0 be purchased?
  • My gas mileage started to deteriorate when E10 was introduced here back in December/January. I was getting a pretty standard 37/38 mph on my daily commute of nearly 100 miles. About 80% highway. My mileage didn't vary that much whether I wen 68 mph or 75.

    By April, the mileage was getting worse, so I suspected more was amiss. I recently had the plugs replaced, air filter, and a complete injector and fuel system cleaning. The only thing left is the fuel filter, in the gas tank, which would prove to be a little costly. My last tank mileage was 32 mpg, which is about equal to my worst tank achieved through stop and go city traffic.

    Currently I'm at 121,000 miles, the car is not quite 4 1/2 years old. What's the next tep here?
  • You are more than likely experiencing better mileage because of the switch to the summer gasoline blend. My average mileage in the colder months is 34. When the changeover to summer gasoline occurs; the average jumps to 41. The winter blend; along with extended periods of choke operation will reduce your cold weather mileage quite a bit. All newer cars are already set up to be as efficient as possible. Other than driving habits, and meticulous maintenance; the only way to improve mileage is changing to harder/smaller tires to reduce your car's rolling resistance.(I did see a slight improvement with synthetic oil and a Fram air filter though) Please report back to us when cold weather arrives and let us know your findings.

    Good luck!!
  • Bought the S manual on Saturday in St Louis and reset the avg mpg to zero after I reached highway speed on interstate for the 130 mile drive home. I varied the speed between 55 and 70 to assist the breakin. I was rather amazed to see 46 mpg when I arrived home. If I had kept the speed at 55 or 60 I would guess it would have much closer to 50. I traded in a Prius with 55k and was given cash back on the new Corolla. If I can keep mpg in this "40" range, I will be very happy with the deal.
  • You may want to compare your computers mileage results to what you get figuring it out with a calculator the old fashioned way. Many cars I have rented returned a higher number than what was actually true. I have "never" acheived 46 MPG in 3.5 years with my 2005 manual. The 2005 is 140 lbs. lighter and smaller than the '09. I doubt the '09 manual would outdo the '05 with basically the same drivetrain. The even much lighter Echo is the only Toyota gas only car that can achieve those kind of numbers.

    You may want to verify your odometers accuracy also. Mine is off almost 2 miles every 100 miles. :)
  • Filled up my first tank and headed home on interstate driving on cruise at 60mph. This was over 90 mile trip and was the car readout. Even if its not 100% accurate, I didn't expect this. I've always been at or a little above the stated highway mpg...but this is way beyond what I expected. We got 42.3 on the first tank combined city/highway. I may have picked up some habits driving the Prius 2 1/2 years...but this is great.

    Just because one person has never achieved a certain mpg does not mean that another person cannot. People drive different speeds and under different conditions.
  • Trust me, I know how to get the maximum mileage out of a car. I've driven this car under all kinds of conditions; at the most efficient speeds. I even know exactly how inaccurate my odometer is. No car is going to get tremendously better "highway" mileage than the EPA says it will get. All I was saying is to check the accuracy of the computer. I know from experience that they are not always accurate. For example,I once rented a Chevy Malibu with a 3.5 liter V-6 (automatic) and drove 900 miles in one weekend. The route was very mountainous; and we hit a "lot" of stop and go traffic. The air conditioner was on for most of the trip. The trip average showed up as 35 MPG on the computer. Would anybody in their right mind believe this was possible?? ? Not me.

    No car is going to get tremendously better "highway" mileage than the EPA says it will get.

    What do you consider "tremendously better"? My current car is EPA rated 29 mpg highway, but I can easily get upper 30s, and sometimes break 40, when crusing under ideal conditions: little headwind, mild temperatures, and speed no more than 65 mph (it does best at 55-60). It will do mid-30s under much less ideal conditions. But I agree it's a good idea to check the accuracy of the mpg computer with manual calculations, just in case there's a big difference.
  • Under the newer EPA ratings; above 6-7 more MPG. Under the older ratings; above 2-3 more MPG. Slowlearner1 was indicating 11 more MPG. That is tremendous IMO. Some people may be misled by unrealistically high numbers and think the Corolla is capable of Hybrid like results. Not gonna happen. You'll need an Echo, Yaris, or Prius to get those higher numbers. The Corolla is too heavy for 45 plus MPG. :)
  • I did not intend to imply that one should expect to get 48mpg on a regular basis. I did get 68mpg once on my Prius...but on average got about 48 in winter and 52 in summer. I haven't had the Corolla long enough to get a feel for what average I'll get, but I wanted to let people to know that under certain conditions it is possible to achieve high mileage. Our first tank did average out to about 42mpg using the dash mpg avg. That was city and I don't think it is so hard to believe it could be 48 driving slowly on the highway? Let me tell you, everybody was passing us. All I can say is that I'm extremely happy with the Corolla.

    Also, I must add that I use safe hypermiler coasting downhill.

    I'm not trying to mislead anyone. I did get 48.8 and if I can, others can too under similar circumstances.
