Your milage is affected by the type of gas. Ethanol reduces gas milage by 5-7 percent in all grades. Each grade increas add about 5 percent.
So, if you are using regular (87) ethanol infected gas and the EPA estimate was done with pure hi-test (93) then you can expect about 15-20 percent less fuel economy than advertized.
Actually, that's not true...not even a little bit. Both 87 and 93 octane fuels have almost the same energy content. The only difference is the vapor pressure (volatility). Engines with higher compression require a fuel with higher vapor pressure so that the fuel doesn't ignite prematurely (causing engine knock). The energy "stored" in that gallon of 87 is virtually the same as 93. If you think you're getting better mileage on premium, it's more likely the placebo effect.
Went to a nearby city this morning and back again. Total mileage was 500km ++ back and forth. Speed was constant at 100kph. Heater turned on at 18-20deg C just to prevent the fog inside because it was -23 a while ago.
Got an ave of 9.9L/100kms as I touched down my parking slot at home.
Mileage could be better, but actually im pretty happy with that - if only I could get that in my day-to-day drive routine.
I called my dealer to report that the recent TSB ECM firmware update made things worse. In my case it increased my fuel consumption even more (from 15-16 to 18-20 L/100 km in mixed driving) and it made the car idling really rough. Their reply was ''yes, we know, there are reports of some people having issues with this update.... we can try put put an older version, which one would you like?''
how am I supposed to know?
anyway, I am schedule to have my car serviced next week
I have a 2013 SX and I get the same MPG as Sorobertson. If you just drive around in stop and go traffic that is all the better gas mileage you get. If I can drive on the flat and at highway speeds it is better as you use the 6th gear in the tranny.
I'm seeing the normal drop in mileage from 27MPG @ 70MPH to 25+. Local garage said they now all have the [U]winter[U] gas blend which reduces mileage 1-3MPG regardless of 89-93 rating. Also remember with 10%Ethol that reduces mileage over non ethol gas. I've given up trying to find local non enthol gas unless I go to a marina, and end up paying more than the benefit mileage increase. Last year in summer, when I found non enthol/summer blend I got over 28+ on the same runs/speed but though that would be unfair to report and would cause hate and discontent amoung the members..
I now have 8K miles on my car and I average 19.3 miles city/highway miles. I was excited to see that KIA has admitted to faking their MPG on the 2013 models but the V6 is not included in this. I have a feeling that mine is incorrect too but there is no way to prove it. What irritates me the most about this whole thing is that KIA bases their MPG on driving 50mpg with one person in the car. I was even told that they take the spare tire out of the car when they do their tests so they get a better rating.
I understand that the car is heavy but unless I drive each car I want to buy for 3-5,000 miles to see what the "actual" mileage is I have to go with what the sticker says and how they market the car. They tell you that this car should average 22 city/highway combined. I get 19 combined. It is a lie to get you to buy the car plain and simple. If I wanted crappy mileage, I would have kept my minivan and drove it into the ground. I am not a lead food driver I am not a fast accelerator either. I do drive 70+ mph because our highways start at that limit. But to base a MPG on conditions that are not even the realm of average is ridiculous and to make it up to suit the EPA is even more ridiculous.
For some reason i dont believe you..Did the kia engineers tell you this? Do you know that many of the new kias and hyundais dont come with spare tires anymore, they have a tire patch kit? And its not a car its a crossover, and not all that heavy for a large crossover. I didnt know that we were supposed to get about 22mpg avg. but that doesnt suprise me since thats about what I get and i can drive rather fast lots of the time which makes me feel even better about the mileage i get. More then likely your just a bad driver, it may not be your fault and you probly dont notice it but dont worry theres plenty of them out there so your not alone. If im wrong then I guess you got stuck with a defective Kia.

I've had my V6 SX AWD for 5 months. In the summer I was getting about 27/19 mpg. One trip I got a little over 28 (that was going from central NJ to Atlantic City, so it was flat ground). Now in the winter I am getting worse. Probably about 25/16. Like others have mentioned, it is probably the winter blend. A trip to Pennslyvania I recently only got 22.1 mpg highway (although quite hilly). That same trip in August I got 25.6. I've been pretty happy so far with the mileage. My Grand Cherokee that I traded in got about 19/15, so anything was better than that!
