#342 of 471 Poor fuel mileage on a 2010 four cylinder Malibu

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

You are not going to get the same mileage in cold weather as in warm, known fact.
#344 of 471 cold weather is not the issue...

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.

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.

QUESTION: ---- Do you think synthetic oil would make a difference in the MPG? --------- Dwayne

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).
#350 of 471 Poor Fuel Mileage on a 2010 four cylinder Malibu

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
