Its an 18 gal tank right? and Im getting about 350 miles per tank which is about 19MPG... Dont they claim like 26mpg combined?

The 350 miles im getting per tank is based on an equal amount of city/highway with a bit more hwy. I drive in ECO mode 90% of the time with cruise control and accelerate slowly most of the time. Yes I drive like a grandmother because my job reqires me to do 1000 miles a week, so trying to conserve gas and im disappointed so far

I have 70k on a 2011 T and most of it highway. I AVERAGE 33 mph on 89 or 87 octane. Theses engines run better on the lower octane. Weird . If you have bad mileage , it's your waste gate not working properly or your air filter is dirty. These air filters last about 7 k as the intakes sucks in bugs, dogs, cats and slower cars. Never seen and intake suck in so much crap in my life!
You may want to look at how much oil is being sucked in to the intake. Thread is available on the fix. Make sure you use 5w40. It is the oil that is recommended by Hyundai for this engine with a max life of 6k before change. Might be 5k. Keep tires at 35psi and use a better tire like Nitto Motiva.

I no longer calculate my mileage. I look at what the computer says and subtract 2. I'm still fine with it.

We get 20/30 on our '11 limited turbo.

If we used the econ setting (don't like it) and drove for mileage we could probably get the epa numbers but we don't.

It means unless you are properly calculating your mileage none of these numbers matter. Everyone gets so fixated on their display but don't realize that thing is weighted toward what ever you did right after your last fill up or reset.

You have to use the fill to fill method dividing your miles traveled by the gallons required to refill.

Oh, I see. I don't use that gauge because it's proved itself useless to me. Fuelly is my friend for gas mileage.

My onboard meter is not to be taken verbatim, by any stretch of the imagination, but it isn't absolutely worthless. When I first had the car I would keep up w/MPG manually and the onboard was usually within 1-1.5mpg of being correct.

I bought some higher octane and have been more heavy on the throttle for first 50 miles and was showing 24.5 after a full tank. Twenty miles of 40-50 in the country keeping my foot out, for the most part still 3-3.5K shift point, had me at 72/27.1.

Then a 21 mile loop of 40-50 has me at 93.4/27.4. Duplicated the next day shows 114.6/28. I drive two miles round trip after idling w/heat on this morning waiting for a sausage biscuit and the OD shows 116.6/27.5.

Is this the software logic that I'd wish to have for one more pass around the dark side of the moon before bringing it back home to good ole terra firma?

Not quite.

It's a fuzzy logic though that is in the ballpark. I quit adding up actual mileage/gallons and checking against the onboard puter thousands of miles ago.

However, since this tank is roughly a blend of half ethanol at 91.1 octane I want to check it and possibly the next couple of fill-ups.

I tried running eco button when I first bought the car as the engine was tight and winter blend wasn't helping. I just grew weary of trying to adapt to it and figured I could come close enough.

I'm not sure what your trying to figure out but octane has nothing to do with mileage. Crappy gas will mess it up but quality 87 octane will yield the same as 93.

I'm just playing a mite looking for the sweet spot for me in the combination of price, mileage and performance.
