I just bought a 2012 Elantra limited last Friday. Too soon to make any judgements on the fuel economy. In reading the maintenance manual I see a recommendation of adding a fuel system cleaner at recommended oil changes. I asked the dealership service manager about this recommendation and his response was that the ethanol is not as clean burning as 100% gas which is the reason for the recommendation. He also said adding the cleaner is like chicken soup, "it can't hurt". At about $15.00/16 oz bottle at the dealership, I think I'll purchase my own Chevron Techtron additive and do it myself. I would like to hear David's (Hyundai Tech) thoughts on the additive.
I recently traded in a 2008 Sante Fe GLS AWD which I liked very much but wanted a vehicle with better gas mileage. Am going through some buyers remorse now as I liked the size of the Sante Fe much better and it felt like a safer vehicle due to it's weight and size. Also like driving higher up so I can see a bit more. I don't drive very much and it will take me years to recoup my "out of pocket" money I spent to purchase the new vehicle with my trade in. Oh well, live and learn!

Maybe you should have waited a few months for the Elantra GT (hatchback)--would have been closer to your Santa Fe in utility.

FYI, the brands of top tier gas that the owner's manual is referring to can be found at www.toptiergas.com. But that doesn't mean brands not listed aren't top tier quality - they just haven't paid to have their gas certified.
As far as Chevron Techron, yeah, $15 for 16 oz bottle is a bit steep. The 20 oz bottles are on sale for $6.50 at Advanced Auto Parts thru Mar 28.

My first full tank off the lot, brand new 35 miles on it, I got about 25 MPG's too. That was expected for the first tank to get poor MPG's. It got better each tank full. I got an AVG of 31.4 MPG's twice. that is with the eco on, and 88 oct.
you have to let that engine get some miles on it... Yes and Yes, it has to loosen up, Brake in.. period. I am coming up on 2000 miles, this last tank. I AVG 30.7
MPG's. It dropped just over one gallon, since the 31.4 MPG'S that I was getting. The last tank I AVG 28.1. On that tank, I turned the Eco off. I did more
city driving, and i drove harder. I was trying to get less that 25 MPG's. Did not get there. Give the car some time to improve on the MPG's..

Ok, this is another update.
This tank, I AVG out 30.7 MPG's, using 86oct. I did not see any difference form using the 88oct.
This time was very interesting. I spent about 45 minutes in stop, and not so go traffic. The fwy was shut down more that 6 hours. So i had to seek out a different route. It took another 40 plus minutes to get to my destination, when I did find a route to use. In stop and go traffic, I was watching the computer MPG's, it did not drop below 26 MPG's, all that time.. I thought that was pretty amazing, compared to what other's have been saying, Less than 25 MPG's. Note: over and hour it took me to get to my destination. It would normally take me, 20 minutes. Then another 30 plus minute driving home. Longer route.
So all in all, I should be AVG over 30 Mpg's. Just about in any situation. MPG's are getting better,
and fwy driving is getting better. I think that is why i ended up with the 30.7 MPG'S overall... I also think i would have gotten better MPG'S if i did not have over an hour of stop and go.. I can see if others are not getting over the 30 MPG's in that type of situation. Stop and go traffic. But i would think overall they can maintain at least or close to 30 MPG's.
Last Note: I will be using 86oct in this tank.. And i will do another update to see what the increase on the MPG's will be.. So far so good

After 18300 miles with my Elantra Limited, I averaged overall 30.3mpg, with about 70/30 highway/city mix. I think anyone averaging 30-32 overall is about the norm. City mileage really seems to eat up the overall mpg's. You will notice the trip computer is always 1-2mpg over than the actual.
I ended up trading mine in for a 12 Jetta diesel premium, Wanted a little more engine and better mpg, but overall the Elantra was a nice little car. I had overhigh expectations for mpg though.
#302 of 774 Look at avg MPH Re: UpDate On The MPG's. [drew11m]

I wonder if too many people aren't overestimating their highway miles and underestimating their city, esp. stop-and-go traffic? A key is to look at your average MPH for each tank. When I started doing that I noticed that my city driving was a higher percentage than I'd have thought, probably due to stop signs and lights. I don't think I've had but one or two tanks where I've averaged over 30 MPH for the tank. When the average MPH are low, means you're spending a high percentage of your time in 1-4 gears of the AT. Absolute best mileage is in 5-6 (overdrive) gears in the 35-55 MPH range.

Yes, there's a direct correlation between average speed and mpg. I saw this demonstrated again today when I filled up both of my cars, my 2010 Sentra and my wife's 2007 Sonata. My average speed on the Sentra was 34 mph and my fuel economy on the tank was 34.8 mpg... which is just above the EPA highway rating of 34 even though a lot of those miles were city/suburban driving. On the Sonata, the average speed was only 15 mph, and the FE was only 18.8 mpg... below the city EPA rating for the car. My wife does a lot of short in-town trips, and sits with the car idling a lot (e.g. waiting for our daughter to come out of school).
I recommend everyone who has an average speed on the trip computer (which the Elantra has) writes that down when they calculate their FE for each tank. Then be sure to reset the average speed when the FE meter is reset.

Yeah, I think the folks who aren't getting good numbers are probably driving more rush hour type driving than they realize and/or not driving as efficiently as they think they are.
I work from home so I don't get to drive in rush hour traffic like many people. I bought my car a couple weeks ago and I'm still on my first tank of gas. So far, on 200 miles driven, maybe 5% is at 55 MPH. The computer is reporting 30.2 MPG with an average speed of 17 MPH. So I'm doing better than the EPA City rating and it still haven't leveled out yet.
Anyone who wants to get better numbers should read the tips in this thread. They work for me.
