Toyota Corolla Real World MPG



  • kenymkenym Posts: 405
    I live in North East Ohio, and starting in November until late March they add some sort of additives to the gasoline to prevent fuel line freeze ups. On average it could be close to 10% reduction in the MPG for that period. :sick: .
  • I own 3 corollas, 09 LE 4 speed auto, 06 CE 5 speed manual, 02 LE 3 speed auto transmission. I receive different MPG with each transmission. The 5 speed manual gets 39-41 on highway at 70+ with air. awesome. The 4 speed auto gets 35-37 on highway and the 3 speed auto gets 32-36 on highway.

    We drive about 50-50 (city/highway) driving sometimes slightly higher for city. Corollas offer the best fuel economy + reliability + resell value (but I don't plan on selling them)

    List your transmission types with your mileage.
  • I agree - the manual is a bit better is seems on MPG. I have a 2006 toyota corolla 5speed. Long interstate drives I get about 37 to 38MPG while in the city I get about 31 to 33 MPG. I think this latter is a bit higher than EPA estimates which are probably automatic transmission numbers - I think it also helps in the city that I coast a lot with the clutch in if I see a stop coming up.

    Wow! I bet you save on fuel with that method but really go thru the burned clutches, huh? Try using the engine for braking instead of coasting up to a stop with the clutch depressed and you'll not only save your clutch but your brake pads as well. Lets see, what cost more, a clutch, brake pads or gasoline?
  • The steering is a little weird but I have become used to it.

    I have a similar issue with my 2007 LE. Within the first year of purchase I took it across country and logged about 42 MPG, and that was with the AC on much of the time. Needless to say I was thrilled. A year later I took it across country again, and I began to notice that the mileage was down by about 7 MPG or so. I even stopped at a dealership on the way because of this concern, who could not give me any reason for it. Air pressure was within acceptable limits.

    My most recent highway trip yielded me around 29 MPG a few months ago. Toyota isn't interested in looking into this and they are acting clueless. I think the problem is probably more widespread than most people realize, and I have a sneaky suspicion that the problem involves the problematic PCM which I'm sure Toyota would prefer for that problem to just go away as they are going to wind up spending a fortune when they are forced to do a recall because of the safety issues.

    I would love to see some people with this same problem all get together and put pressure on Toyota or some regulatory agency to have something done about this

    What is a problematic PCM ?

  • That seems like a pretty dramatic fall off. I thought I had a similar thing with my 2006 corolla - when I first got it (used), thought I was getting about 39 to 41 on the highway. Immediately after putting on new Michelin tires, it dropped to about 36 to 38. Turns out the older tires were just worn and hence giving a shorter travel distance per revolution. This showed up in my MPG calculation as a longer distance than I was actually traveling (the odometer is counting revolutions not distance). For good MPG accuracy should calibrate your odometer to actual distance - I did this on the interstate by noting what my odometer read after travelling about 100miles by the mile markers on the side of the road. With the old tires, I am guessing that 100mile physical distance would have shown up on the odometer as something like 103 to 105. My new tires, incidentally, are a little "taller" (kind of odd terminology, but what the mechanics use for "diameter") and I have to adjust my reported miles up by 1.01X. I am getting 1% more actual distance per revolution than the odometer is expecting.

    This is unlikely to account for all of the drop you are seeing, but something to consider.

    More aggressive tread, ie M/S, and wider tires will not give as good mileage as narrower "Smoother" treaded tires.

    Interesting, when the the PCM (whatever that is) become problematic? First I've heard ! Perhaps the time of year you took your second trip could have been a determining factor in your lower gas mileage. In the winter months in certain areas more additives are added to the gasoline which hurt gas mileage. Can't say I can fault Toyota for brushing you off regarding why your getting ONLY getting 35 mpg on the highway when you think you should be getting 42. Do ya think they got more important things to worry about ???????

    I have a 04 Corolla base model with 70K miles and MPG is been great! Went to Vegas on Jan for CE show and averaged 44.78MPG. The trip was from Chula Vista to Las Vegas using almost all I15 and I drove around 70-75. PSI was 36-38. On normal daily use, we get 33-35MPG, and if we go to LA, there is a good chance getting close to 40MPG, if there is no traffic.

    hi my 2006 toyota camry le v6 automatic average 32.3 mpg for 738.6 miles driven... warm weather driving. no ac/heater. 95 % highway, cruise.. the car have 176,000 miles. 29-30 mpg is very easy..

    I am using shell 87 octane.. I am going to test shell 91 v-power to see if I can get 33-35 mpg.
  • terceltomterceltom Allentown, PSPosts: 1,024
    The cost of the premium gasoline will most likely off set any MPG savings you have.
  • dudleyrdudleyr Posts: 3,469
    Higher octane will not give better mpg unless your car is tuned for it (timing is advanced).
  • dvd0060dvd0060 Posts: 8
    I have excellent MPG. I can average as High as 48.5 on the highway no A.C
    with A.C 47.9. In the city it never drips below 29. For the week on average I get between 30-36 depending on how much highway driving I do. Yes, I drive at 60 on the highway...............not less,not more. in the city about the speed limit or just above.
    I've touched 52mpg average again just going 60 mph. I think that speed is reasonable.
  • terceltomterceltom Allentown, PSPosts: 1,024
    Wow, that's great! I can't get more than 26 in the city on both my 2001 and my 2009. What year is your Corolla?
  • mnfmnf Spokane WaPosts: 405
    I get a average of 30-32 in town with a 60/40 split ( Hwy-city) on trips the best i have gotten is 36-38 on the Hwy. No i dont go 60 usually 65-75 mph in the speed limits of 60-70.

  • Automatic or manual?

    Just got my first oil change at the local Valvoline. They put in 5w30, like an Idiot I didn't think about it. I immediately notice a difference in my gas mileage about 2-3 miles per gallon less. ON oil cap it states 5w20. I went to the local Toyo dealer, had them do another oil change using 5w20. Gas mileage is back up. One thing I keep my tire slightly over inflated at just 32 pounds. The dealer adjusted the pressure down to 30 again. At 32 pounds I can touch 50 mpg on the highway doing just 60 and using cruise.

    I would have probably given 5w30 a longer chance, 2-3 miles per gallon mpg difference sounds like it might have just been an over-calculation. Other than synthetic vs. dino oil, these oils aren't that much different in weight. Just curious though, you followed Toyota's recommended oil so precisely, yet you through their recommended tire pressures to the wind. You're willing to compromise handling and safety for a few bucks ? I think it's especially important to follow Toyota's recommended tire pressures with the very light touch of the EPS steering.

    I hear you. by inflating the tire by only two pounds more I find the handling less mushy. I spoke to a trusted mechanic about it and he seems to think 2 pounds is no big deal, ten pounds maybe.
  • echo2001echo2001 Posts: 17
    Get about 33 MPG Avg 20% city, 80% HWY

    I've been running 38-40 pounds of air in my '05 Corolla for years with no problems other than the ride being a bit stiffer, but never uncomfortable. I drop the pressure to 38 pounds in the winter when ride becomes stiffer in cold weather.

    The increased tire pressure does make a difference with improved handling, fuel economy & tire wear remains excellent & even. Warm weather average is 40 MPG (39 city/41 highway) with a 50/50 mix of driving. This is possible only with the 5 speed manual when using shifting techniques to reduce engine pumping losses. The automatic is great on the highway, but unremarkable in the city.

    I had an '02 with the 4 speed auto & hated it because of the inherent downshifting/lateshifting resulting in a higher RPM fuel consumption penalty during city driving. (30 city/40 highway)
  • I had same problem.
    The 2010 corolla I bought had only about 28 MPG in highway, about 3 miles lower than city(45MPH). This is definitely a problem they need to face.

    Gas mileage is not a common problem in the 2009 and 2010 Corollas. Notice the dates on the posts on this thread, it seems to be that only a few new Corolla owners believe they have a problem. Gas mileage is very tricky for some owners to track. Perhaps you are having some kind of isolated problem on your vehicle that should be checked. With my partcular style of driving I get 27 city and 39 highway on my "09" Corolla and am very satisfied. These same figures seem to be very consistant with my "92" and "01" Corolla as well. Actually, my "02" Celica and my "86" tercel were very similar as well. All had basically the same motor.
  • i drive on a lot of slow back rodes and small towns and some highway. pretty much zero stop and go city traffic. my 09 automatic le gets probably about 33 average
  • I recently made a 110 mile round trip and averaged 39.3 mpg on the trip!!! Freaking awesome!!! Say what you want about the steering/paint/whatever, but the drive train on this car is flawless. Engine runs like a top and the automatic transmission can barely be felt when it shifts gears. 39 mpg is why you buy this car.
  • kipkkipk Posts: 1,576
    I agree!

    We recently had a Corolla "S" rental with the 1.8L engine and auto tranny for a few days while my wifes RAV4 was in the dealers shop for a hard to find problem.

    In local driving I averaged in the high 30s mpg. With some stop signs and traffic lights and little traffic. My wife averaged in the mid 30s commuting to work, with medium traffic and several traffic lights and stop signs and a bit of stop and go. . For comparison she averages 22-24 with the Rav4 auto and 2.5L 4 cylinder. I took it on a short trip on back roads, with just me in the car and averaged in the mid 40s. We took it to church with 3 inside and averaged 41+ mpg.

    These mileages are from the on board dash gauge and it is likely a bit optimistic. However when comparing it to the gauged mileages we are getting on our Honda Ridgeline V6 and Rav4, the Corolla is a winner by a long shot. And yes, the tranny shifts were almost un detectable unless I monitored the tach.

    Great little car.

    Oh yeah! The steering in these cars is awesome, I've been saying that all along on the EPS Steering board. I have a 2009 Corolla and never had a problem. I get 39 MPG consistanly on the highway and A.C. on with my 2001 Corolla as well as my 2009 Corolla.
