    Hello Lemonmalibu,
    I did send you an email. Please let me know if you don't receive it. Thank you,

  • Hi all,

    I have 820 miles on my 4 clyinder 6 speed 1LT. Up to now I have HORRIBLE gas mileage of 15.1 mpg, per the DIC system and also my calculations. Granted most of my driving is in Queens NY with stop and go traffic, I also drove with the fan on speed 2 for most of 2 weeks, for we have had some heatwave in NYC lately

    I just reset my DIC AVG and plan to drive to maximize my MPG I will report after 2 more tank fulls.

    I intend to drive with the INSTANT MPG readout on screen, maybe this can help me drive to maximize MPG. Does anybody use this INSTANT MPG readout for this purpose?? If so any success?

    Lastly I think my 2010 1LT may have a touch of what lemonmalibu has described. Ive asked 2 people to drive it a bit and they say they like how it drives but can feel some hesitation or jump.... I will take it to my mechanic soon and will report.

    Best to all,
  • Hello,

    No action on this board, too bad.

    Well I am upadating my previous post. I recently took a road trip and got somewhere over the advertised 33mpg on strictly HWY miles.. yippeeeee.
    However my City miles are still lagging the advertised 20mpg.
    After driving veeeeeery carefully around the city trying to manage my MPG optimally, Im still getting only about 16-17 mpg. But I am happy bout my HWY mpg.

    I havent taken my car in yet for service but I will soon and will post if there is any
    success with my CITY mpg..

    You're doing better than me. I have yet to crack 30 mpg. In fact, my best is 29 - or would have been if I hadn't had to get off the interstate to fill up. Usually, I get 27 to 28 with steady state cruising. Of course, here in the midwest, highway speed limits are 70 mph and an additional 5 mph is usually a 'gimme', so that means setting the cruise at 75. I could probably do better with the cruise set at 65, but then I'd be a road hazard. ;)
    Around town - some urban, some suburban and a bunch of freeway (interstate loop), I get low 20's - about 22. If I actually drive just around the 'burbs or in the city, I get high teens.
    I just keep thinking - for that kind of mileage, I coulda had a V6. And, actually, my Corvette with the 350 V8 gets just as good a mileage. Of course, it takes premium fuel, but it's also a LOT more fun to drive. And it can get out of its own way - something the Malibu with the 4A has trouble doing, unless you're really flogging it.

    My 05 Base just returned from another "college trip" between MA and
    TN (about 1100 miles each way).

    There (loaded): 35.9. Back (empty): 36.9.

    The trip included plenty of mountain climbing in NY, PA, and TN (a gross
    MPG killer), and some stop-and-go on the way "there". This time I
    also made two fill-ups at the south and north borders of VA, a
    relatively flat road. For that span of the road (back), the result
    (by the fuel purchased) is 40.4 MPG, better than I expected.

    A bit under 42K miles on the car now, and I've been happy with it.
  • 2010 Malibu LS 4 cyl. with 2300 miles
    I live in Brooklyn NY and I use 87 and 89 octane gasoline.
    With A/C on Hwy average is 32-35 mpg but city is very bad, between 12.7-14 mpg
    I have this car since April 28, 2010 and truly regret buying it for few reasons.
    I was going to buy Camry but Malibu had a factory rebate at the time that is why I went for Malibu. BIG MISTAKE.
    I've had 2006 Chevy Equinox before and city milage was about 17 mpg.
  • I have about 2600 miles on my 2010 Malibu.
    My October MPG average was very bad 10.9
    No A/C, no sitting in traffic, just normal city driving
  • malexbumalexbu Posts: 169
    Comparing your two posts: 09/05 -- 2300 miles, 10/31 -- 2600 miles on the odometer.
    300 miles in two months? 150 in one month? I find it hard to call in a "normal city driving". How many gallons on gas have you purchased to drive those 300 miles? You do one fillup a month? Sorry, your numbers look suspicious to me.

    2007 Malibu Maxx LTS, 6-cyl with only 35,000 miles on it
    I am getting only about 20 mpg according to the display, but my avg speed is only 29-30, with 50/50 highway & stop-&-go local driving. MPG is much better on long, hwy trips of course (25+), but I was hoping it would be better overall.

    QUESTION: ---- What brand of tires are on your Malibu? ---- What pressure are you running to get those MPG figures? ----- Dwayne (Owner of a 2010 four cylinder LTZ with a 6 speed auto trans that only gets 27 MPG on the highway.)
  • djm2djm2 Posts: 705
    Hi all: ------------ Chevrolet and General Motors owes the owners of the "four cylinder Malibu" reasons why we are not getting the posted highway mileage of 30 to 33 mpg! ---- (They advertise these figures, ----- but many of us have not seen these figures in the real world! ----- WHY?) ----- Many of us have purchased these vehicles because of this posted mileage! ---------- Best regards! ------ Dwayne :shades: :confuse: ;) :)
  • gonogogonogo Posts: 869
    You are not going to get the same mileage in cold weather as in warm, known fact.
  • phil53phil53 Posts: 54
    I agree with Dwayne - to an extent.
    And I would tell 'gonogo' that cold weather appears to have little to do with it. I've owned my 09 LTZ 4cyl 6A since they came out and I have never seen 30 mpg - not once, in any weather. Actually, my wife saw right at 30 mpg once - on a trip from KC to DM doing all interstate driving. The best mileage I have ever seen (same route) was about 28 mpg. Normally, in combined driving, I get around 22 mpg. For that kind of mileage, I coulda had a V6! I will also note that this is the first GM product where I haven't gotten the advertised mileage or even close to it.
    As to Dwayne's observation, the reason we don't see those kinds of mileage figures is that we don't drive like the EPA loop nor are we hyper-milers. We are just ordinary drivers who get in our cars and drive them. And, since these are little 4 bangers whose transmissions are tuned for mileage instead of performance, it actually back-fires and we see worse than we should. I'm guessing if I had a 6M, I would see better mileage - but still not what is advertised on the sticker.

    You comments are right on the money! ----- The four cylinder in this car IS NOT sufficient to power this vehicle. ---- (It is working too hard to move the vehicle!) This is where the mileage is going!!!! ---- It does not come close to a four cylinder Honda Accord engine. (What was GM thinking putting this "toy of an engine" in this vehicle?) ------ Maybe if this engine had a Turbo something might happen! ---- In addition, the "original equipment tires" ARE NOT "mileage friendly tires." ---- They are at the low end of the tire spectrum! ----- I am seriously considering putting on four Michelin tires at a cost of $888.00. --- I will
    bet this will improve the mileage. ---------- Best regards. ----- Dwayne. :shades: ;) :)

    Keep in mind that high mpg (i.e., low rolling resistance) tires sacrifice performance to achieve their goal. And sometimes comfort. So you have to be aware of the trade-offs going in.
    Personally, I prefer performance over mpg. But that's just me.
    As an interesting side-note, I recently found myself in a Dodge Avenger rental car. Now, this car was nowhere near as polished or comfortable as my Malibu. But the thing I noticed is that I had better response, smoother shifts and seemed to get similar mileage. The engine was the same size, although not quite as powerful and I'd bet that the transmission was a 5 speed at best - maybe a 4 speed. So this is an area where the Malibu really disappoints.

    QUESTION: ---- Why can Honda build a four cylinder engine that performs in the Accord, but the American Manufacturer cannot seem to engineer the same technology? ----- Did we forget how to build an engine? ------- Dwayne.
  • djm2djm2 Posts: 705
    QUESTION: ---- Do you think synthetic oil would make a difference in the MPG? --------- Dwayne
  • phil53phil53 Posts: 54
    I have used synthetic in my car since the first oil change. And my mileage is not that great.
    On the other hand, I wait until the 'oil life' read-out on the DIC is down to single digits - or, at least low double digits - before I change oil. I'm not changing oil nearly as often as I used to under the old 5000 mile rule and I suspect that my engine is better protected (although it's hard to prove without tearing it down).

    Hi All:

    We have all been discussing the poor fuel mileage on the four cylinder Malibu! ---- We have been discussing the possible causes of this condition.

    I am sure that there are General Motors Representatives on this forum. ---- Why haven't they joined the discussion, and in the process, share some insights from the factory point of view?

    Best regards? ----------- Dwayne :shades: :confuse: ;) :)
