These are for the 2008 Elantra, different engine, but still interesting I think in light of your post re ethanol content:
And this more general comment re ethanol-laced gas and Hyundais:
What does your car's owner's manual say about ethanol content in the gas? Does it say 15 percent ethanol (E15) is OK? If so, you should show that page to your dealer. There's a lot of buzz on the Internet about whether E15 can be used with all newer cars, even though the EPA has given it its blessing. However, pumps that dispense E15 are supposed to be clearly labeled as such, as it is not supposed to be used on any pre-2001 vehicles.
And since YOUR car seems to have been affected adversely by E15, I wonder if that can explain at least some of the other cases where owners are dissatisfied with the FE on their Elantras?

I drive 95% highway. So guess what? I care. But I also know how much difference in FE 5 MPH can make, and how some people (not making any accusations or implications) like to wave off the fact that their "highway" driving might be at 80 MPH as they wonder why they're not getting the MPGs the EPA got on their 65 MPH "highway" test. It's important to keep in mind. And whether you care about "point in time" or not, a "point in time" where you do 85 MPH will reduce your average MPG.

The Elantra owner's manual warns not to use gas containing more than 10% ethanol and states that the warranty may not cover any damage caused by using it.

So much for E15 not harming anything built after 2001.

That's common knowledge. The 2001 cutoff means, don't EVER EVER put E15 in a pre-2001 car. Newer cars... check with the manufacturer. E15 is so new only the newest cars will mention it in the owner's manual. If the manual says something about E10 being OK, don't assume E15 is also.

Common for who? From what I've read previously I thought it was OK to use the E15 in post 2001 vehicles. I think I stay up on auto industry news pretty well so I have to believe the average person doesn't have a clue.

Just do a google on "E15 gasoline" and you'll get several hits about the controversy on whether E15 is safe for post-2001 vehicles. I just did it (again) and the first hit was pretty good:

Our 2012 limited is coming up on 6,000 miles.
We avg about 26 mph overall but much of our driving is non highway.
On the rare occasion that I do take a trip I can get 36-40 on the highway. I have just resigned to the fact that 26 is tops based on how we drive our car.
I would love to avg 33 but that is just not realistic.

Since you've been tracking the FE for your Elantra, what were your actual results for some of your most recent tankfuls of gas? Say the last 2 or 3 tankfuls?
- What was the average MPH for the tank?
- How many miles did you drive for the tankful?
- How many gals of gas did you pump into your tank for the tankful?
- Are you using ethanol?
- Do you do a lot of stop and go city driving?
- How many drivers are there for your car and are they driving similarly?
- Are you routinely carrying passengers while doing city driving?
- Are you routinely using A/C while doing city driving?
- How did your car's computer MPG estimate compare to what you came up with based on actual miles driven and actual gals used?
#574 of 774 MT's Elantra struggling with FE, just 26.8 mpg
Jul 21, 2012 (4:53 am)
September '12 issue of MT has an update on their long-term '12 Elantra. After 9 months and 19,593 miles of driving, MT has only been able to average a woeful 26.8 mpg! Compare to...at just 4 months and 6774 miles MT achieving 24.3 mpg in their '12 Passat 2.5 SEL, which is only EPA'd at 22 city/31 hwy/25 comb. (Their '11 Jetta TDI is at 39.5 mpg after 36,643 miles, with EPA est. at 30/42/34.)
