"Do you own an Optima yourself...?"
 
Yes, we do. We bought the LX-V6 (Bright Silver) on 6/23/06 from Crown Kia. The mileage is just over 6K, with no real trouble at all. The only thing that did happen was the TPMS light came on due to, we were told, a sensor out of calibration. They re-set the light, no further problem.
 
Our MPG, with two different drivers, mostly urban interstate, runs a consistent 23.4. And, at least when I drive, all six of the cylinders get used...
 
I like the car. I like the Dealer. We will almost certainly buy another Kia.

I'm glad one of us is satisfied.If my gas mileage eventually matches my 2006 Sonata's,I will accept this Hyundai stepchild.
As far as the dealer is concerned,I bought my Hyundai Sonata and the KIA Optima from a giant multi-brand complex,Lujack motors in Davenport Iowa.The service dept.for Hyundai was A+,but I had a less positive relationship with the KIA.Maybe it was just me,but I started taking my car to a different dealer,so things are looking up.BTW,your mileage...has it increased dramatically once you passed 5000K?

my wife filled up this week. First major trip later this week. Frankly I'm averaging about the same with the Optima 4 as the Malibu Maxx 6. 22-23 around town and low thirties on highway. That's about 2 mpg less than I got with my Elantra and about what I expected. If it's typical Hyundai it will go up about 1-2 mpg when fully broken in.
 
Mickeyrom, your reported mileage with the Hyundai was exceptional.

Your 23MPG around town is what is truly exceptional.My Sonata got that average up by the great Hwy mileage,because in the city it never reached even 15.Usually a little over 14 thats all,but once it was rolling it would register as much as 37 on the computer,which was within a mile or so of actual.
BTW Im currently doing a full tank on strictly city driving,and its not so cold any more.When I do a fill up I will do a report on that.I'm hoping that this time it at least matches the Sonata's 14-15 MPG.

There are mpg calculators AND mpg calculators.
 
My Maxx shows an averaged mpg reading. It obviously changes rapidly when the tank's filled then levels out. It's presently showing 23.5 mpg (probably 1.5 mpg optimistic), at about half a tank. If I went on a two hundred mile trip it might increase to 25 or 26. If I continue driving mostly around town it will average somewhere around 22-24 when I fill it up.
 
I've had rental cars (Chrysler vans) that showed the actual second by second computations. This could go from 3 mpg to 50 mpg depending on what you were doing at the moment.
 
What's the 14/37? A computation of mostly around town and mostly on the highway or some kind of second-by-second computation?

The Sonata's computer only shows a cumulative MPG.The 14 I got from an actual calculation.Miles divided by gallons.The 37 was on the computer,but as I said the computer was always within a mile of the actual mileage.I got the number by resetting the MPG calculator on the computer while the car was rolling down the highway.After a minute or so the actual mileage pops up.Mine was sometimes 37 and stayed there until I got off the road.Even fighting heavy construction traffic going past Gary Ind. on I80,the mileage stayed around 34 for the whole trip to Sandusky Ohio.Thats 400 miles or so.However,all of my posted MPG is strictly the manual figuring(calculator)not the computer.

I have a 2006.5 Kia Optima with 17,000 miles and I am currently averaging 26/37 mpg, I swapped out the stock plugs which actually extremely detune the car, I upgraded to the premium Denso Irridium Plugs IK16/5303(.004mm Core) which are available at autozone for $56.17 with tax by doing so I shaved 3+ seconds off my zero to sixty time and I can easily burn a 07' Camry V6, I burned 4 of them as a matter of fact and my gas milage improve also, unfortunately now I have a lot of wheel spin from a light and now all four of my tires are nearly bald despite regulary rotating them, I would definately recommend a stickier tire,I haven't had any problems with the seats and airbags, I think thats a early 2006.5 model problem. My only gripe is a delay in down shifiting which was fixed in the Sonata with a reflash but there isn't a reflash for the Optima as of yet. I can't wait for a K&N to be available for it and some performance struts not that it doesn't handle well as is.
