I find my mileage extremely dependent on how far I have to drive and the type of driving. If I do all short stop and go trips (no freeways), less than 3 miles, and never give the car a chance to warm up, I get about 16 mpg (based on the mpg computer, which I've found to be fairly accurate). I can drop this down to 14 mpg if I accelerate hard every time I start out (something I normally don't do, but for the sake of science it was fun). If I do all stop and go trips, but for 9 miles total, giving the engine, transmission, and exhaust system a chance to come up to full temperature, I average 17 to 18 mpg. I find that once the vehicle is fully warmed up (and I reset the computer), I will get between 19 and 21 mpg stop and go driving (based on how far you drive between each stop - it's the "go" part that eats the gas).
 
On the freeway, driving at a constant 65-70 with the engine warmed up, I will get about 24 to 26 mpg, depending on terrain and wind direction/velocity. I was able to get it up to 29 mpg once, but that must have been a fluke.
 
So you see, real world MPG is somewhat nebulous and can vary greatly depending on how you drive, the roads you drive on, and most importantly, the length of your trips. What they say about bunching up all your errands so you only need to go out once really does make a lot of sense. A cold engine is a gas hog, plus that's when it does 90% of it's polluting since the catalytic converter is not heated up.
 
I've owned a 2007 SF Limited AWD with third row seat for two months now and absolutely love it. It's so much fun to drive. I have about 1200 miles on it.

NYC numbers: In stop and go I am getting 15/19 on my 07 3.3 AWD Limited. I just took a 400+ mile trip and I got 23 on the highway. Not bad considering I never fell below 65mph on average. The Santa is an awesome SUV for the money. This is my third one. The only major issue was on my 2003. My transfer case started to hum. Taking no chances Hyundai replaced it in 2 days and provided me with a loaner( Sonata ). When you compare all the features it has against the competition, its a no brainer. If fuel economy is high on your list then you should be looking for a four cylinder/hybrid. ( Not offered in 07 Santa's ). Good luck!

I wouild like to add that mpg in my 07 Fe Gls is very dependent on highway speed. With the 4sp auto the rpm at 75mph are about 3k, which wont get you close to epa at least not on mine anyway. That is about the only drawback on this vehicle is highway rpm. Needs another gear for gls trim!

#18 of 506 Miles per Gallon---- by kg325

I have a 2006 2.7 V6 Sante Fe. How can I get more than 13 1/2 - 14 miles per gallon?
The service manager in Utica told me the break-in mileage is 8000 miles, I find this hard to believe. He also said no one has had a problem with mileage.
Can I expect any better mileage?

Thanks for your reply----
I am what you might call anal, about maintenance and up keep. So the 10 tips, I am aware of them.
My Sante Fe has about 2200 mile on it.
I have noticed that it downshifts at times at 32 miles per hour, when I am coasting to a stop or just following traffic. It seems to downshift too early. It also seems to stay in a gear while upshifting.
Is this a characteric of this transmission or does it need attention?

#21 of 506 Regular Unleaded by srdriver

The Santa Fe calls for 87 Octane regular unleaded.
 
That is all we have used in the past several vehicles we have owned.
 
Has anyone seen any benefit in using a higher octane gasoline?

I haven't experienced any difference yet. I haven't tried it in this vehicle.
Since it is new, I am following the manufacturers guidelines(87 octane) so if it doesn't perform like it should I can tell the garage.
My mileage is terrible so far.

One thing we do is use Lucas Fuel Treatment at the rate of between 2.5 and 3 oz per 10 gallons of regular unleaded gasoline.
 
We have good luck using Shell, Chevron/Texaco, or Phillips 66 Regular Unleaded.
 
I buy the 5.25 oz bottle of Lucas and refill it from a large bottle.
 
I put about 3 oz in the small bottle and when I am down about 10 gallons of gasoline, add the Lucas then top off with gas so it gets mixed up good.
 
We use it in both vehicles.

I see what you mean. Lucas is supposed to be good, even their transmission additive.
But until mine is running within the mileage range as advertised, I wont put any additive in.
I'm getting 13 1/2 to 14 1/2 mpg.
What is the normal breakin period for these?? The service manager sugested to me 8000 to 10,000 miles. I have never heard of anything like that before!!!
