    How do you mean downsizing...like a KIA Rio? May I suggest the Hyundai Elantra? Great mileage and quite roomy.

    I know your pain. I recently rented a 4 cyl. auto Optima w/ 5k miles. It got 20 mpg with mostly highway miles and 1/3 the time with the AC on. That's pitiful. I should have seen mid 20's in the flattest state (Florida). I wanted to see what the real world said about the mileage. Now I see I wasn't the only one to see poor MPG. I recently bought a 2008 Mitsubishi Lancer (2 liter, auto) and am averaging 32 mpg (mostly highway). Talked to another owner of a Lancer who hasn't seen less than 25 mpg which is consistent with EPA standards. My wife and I think it's a nicer, albeit slightly smaller car than the Optima. Just my 2 cents. The Saturn Astra is also one heck of a deal right now and a really fun car to drive, just a little too much money for my budget (we haggled a great deal on the Mitsubishi).

    Speaking of my 2006.5 KIA Optime with the I4 engine and automatic,The only time I get less than 33MPG on the highwy was when there is a terrific head wind.Then I got just under 25MPG.My only complaint is the gas I use in the city.That is not too good,but I attribute that to the fact that those locar trips are so short that the car never gets a chance to warm up.

    We just purchased an 2008 optima and think the ride is a little harsh with lots of noise in the cabin going over the tar strips on rough interstate roads. we had the body undercoated thinking it might help but much difference. and comments?
  • mickeyrommickeyrom Posts: 936
    The Optima is a fairly hard riding car,but not any more than my friends Jag. If you have 17 " wheels then it would even be harder.I fill my tires with 35 Lbs of air and it helps the mileage but makes the ride even harder.I'm used to it now and just accept the reality that it's a KIA Optima,not a Mercedes. It's not a luxury car.On good roads I like the ride just fine.

    do you have the 2008 Mitsubishi Lancer GTS? Or the DS or GL? All are good cars. I bought a 2008 Mitsubishi Lancer GTS in Rally Red and automatic CVT tranny, Sun and Sound Package(650-watt Rockford Fosgate 9-speaker AM/FM/CD/MP3 stereo ;) and sunroof) but the lower-cost models would be a good deal and would be a good, solid car. I have the P205/45R18 Dunlop Sport Performance radials and the 10-spoke alloy wheels. With the wrap-around bodykit the car is an absolute knockout!

    I do like the Kia Optima a lot, too, hence my interest in coming to this thread on Edmunds.

    I have the 2008 ES (red) w/ 2L I4, CVT, Sun & Sound package, 5 spoke alloys. Stereo is easily one of the best factory installs on the market period. And I'm picky about my stereos. The low profile tires aren't such a great suggestion in Maine with our bad winters. Potholes abound & more than once I've seen low profile tires peeled right off the rims. And as for the trim kit, unfortunately that's a place for road salt to collect and rust out the fenders. Further south and I would have done it in a heartbeat. That said, the car is still a looker. Get lots of interested looks.

    I'm not saying bad things about the KIA. I think they have made huge strides in quality improvement. It is cavernous inside and the seats are good. The controls except the steering wheel stereo and cruise switches are intuitive. I just think the Mitsubishi represents a better value despite the smaller size. :)

    primo. Mitsubishi enrolls in the Paris-Dakar races with their Outlander's and Lancer's and wins them, then rolls whatever they learned from those racing experieinces in to the production of their new automobiles. I am totally smitten by my '08 Lancer GTS.

    What color is your Lancer, broonsby? I put this new Lancer bodystyle right there with the '65 Ford Mustang as my favorite car bodystyles in automotive history.

    No offense, but isn't there a site dedicated to Mitsubishis? As an aside,when I was stationed in Nagoya Japan back in the 50s,my base (Ozone coumpound) was accross the street from a huge Mitsu. factory complex.I guess that is where they built Zeros.
  • broonsbybroonsby Posts: 13
    No offense taken. As I've said in my previous posts, I just didn't like the gas mileage (20mpg is unimpressive) and was nit-picking about the controls. The mileage could easily have been affected by abuse the car has taken earlier since it was a rental.

    And as I would like to point out, KIA is Killed-In-Action - Korean style. We are at least not at war with Japan anymore (not militarily at least). Yes, I know it is made in South Korea, a country we don't have an issue, but we spilled a lot of blood there for a stalemate.

    Okay, let's get back to the subject here which is the fuel economy of Optimas in th real world.

    Other comments aren't appropriate here, thanks.
  • mickeyrommickeyrom Posts: 936
    Well...I love my KIA...great ride and looks great too.
  • patpat Posts: 10,421
    Share with us again your mileage? :)
  • mickeyrommickeyrom Posts: 936
    last time I averaged...10 fill ups...31.4 about 90% highway.
    My very last highway fill up was 37.9,that was almost all highway,maybe 98%.
    Like I said,very good on the highway,and very mediocre in the city,mostly because my car makes such short trips,less than 2 miles,that it doesn't get a chance to get warm.Somewhere between 14 & 15.
    If the driving was split even, 50-50,it's about 23-24 MPG.
    I have not filled up recently,but after driving from Sandusky Oh to Kewanee Il,my computer indicated I had 130 miles left to empty.I have no complaints with that.
  • barguglbargugl Posts: 26
    Ok. I have my first mostly highway tank. 85% highway/15% town and I ended up with 30mpg. I am up to about 2700 miles total now. Total mileage is 23.3mpg with 30% Highway/70% town.
  • mickeyrommickeyrom Posts: 936
    Sounds about right..
  • I have a 2007 4cyl with auto and i am averaging 25 to 28 mostly hwy driving. I thought it would average over 30. I use cruise control and drive the posted speed limit which is not over 70 mph. Let me know if I am out of line complaining about the mileage I am getting. By the way I have 14300 miles on the Optima so I should be past the break in period. Any help out there? Thanks

    Just bought the LX 4-cylinder manual and very happy with the ride and fit of the construction. But initial mpg with A/C on in the city is not good (<17mpg) for a 4 cylinder. However, without A/C and about 50% city/highway = 25mpg. With gas in LA @ 4.70/gallon, the joy of buying the KIA at such a good price compared to a Toyota is tempered down with the real world, poor mpg's. Any suggestions? Thanks.
  • mickeyrommickeyrom Posts: 936
    Your in town gas mileage (17) isn't all that bad.My Optima EX 4cyl, auto gets a lot less.It pretty much depends on how far you drive.Is the engine warmed up,or are you making very short trips as I do...less than 2 miles.
    According to Consumer Reports, real world MPG on a 4 cylinder Optima with automatic tranny is 15 city 33 highway.BTW I have 35lbs of air in my tires. That seems to help. I have gotten as much as 40.7 on a long interstate drive.
    I have not noticed any worse gas consumption with the AC on. Matter of fact,I get better MPG in the summer with the AC on than in the winter.

    Your 25 mpg for 50/50 city/highway is very close to the EPA estimate. And it's a new engine. Hyundai engines (which the Optima has) tend to improve in FE as they age (actually that is pretty common with other brands too). Keep checking the mpg and drive moderately, and see what happens. Also try taking the car on a long cruise on the highway and see what it does there, at a reasonable speed e.g. 70 mph or less.
  • mingdoimingdoi Posts: 4
    Thanks for the replies regarding the mpg on my new Optima. I will keep an eye on the mpg's as the car ages and will also increase the psi on the tires.

    Also, decided to poke under the hood and was surprised to find a loose, detached hose from the air intake to the filter. Reattached and hopefully will help. I guess the dealer's new car check was not too thorough.
  • csandstecsandste Posts: 1,866
    About 10% under my Maxx V-6 and 20% under my 01 Elantra. Mostly my wife's drive and she doesn't make much use of cruise. Still, far from good.
  • mingdoimingdoi Posts: 4
    Well, I now have over 1K miles on the Optima and I run with 25mpg combined. However, highway driving has been amazing; almost 35mpg. I inflated the tires to the max. and have also used some (safe) hypermiling techniques. :)
  • mickeyrommickeyrom Posts: 936
    How many pounds is to the "max"?
  • Hey guys...

    Max tire pressure depends on the tire. Look on the sidewall...better yet, if you have a tire store nearby, ask them the max. PSI they would suggest running in the tire. Realize that there are some tradeoffs, more PSI means less contact with the road (less friction) for stopping but also less contact with the road (again, less friction) for better gas milage. So, realize that a happy medium might be the best solution...I would much rather spend more money in gas than several thousand in repair costs and higher insurance payments...not to mention the precious cargo.

    I have an '02 Optima and here is what I have learned over the 120K I now have on the car.
    1. I run the tires at about 35 psi. This is about 2/3s max psi.
    2. I actually get better gas milage by not using the cruise control. It allows me to feather the gas to speed up or slow down instead of the hard on/off that the cruise seems to have.
    3. I use Mobile 1 7500K oil. This seems to be the best as far as viscosity breakdown vs cost. Mobile 1 is excellent oil...the only one I will use.
    4. I have experimented with speed on the freeway, from 55mph to 80mph (max I'll admit to) which is 5mph over the posted limit. These experiments on long trips have led to an understanding that air resistance is a huge factor in the MPG factor. If you want the best MPG, stick to 55mph...it's that simple. At 55mph I get 37 MPG on the freeway, at 80mph I get 18 MPG.
    5. I use a K&N air filter. It's expensive, but will outlast your car. You can let it get very dirty and it will still have far more airflow than a new paper filter. (I know, I know...K&N let's small particles in that will ruin the engine... Well, after 120K I have no pressure loss which tells me that this is crap! It might also be that I let the filter run a little dirty most of the time which helps trap more of the small stuff.)
    6. I use Lucas Oil additive in every oil change.
    7. I use a product called ER (Energy Release). After I had an experience with a Honda Accord transmission that I thought was trashed and got the gear shift handle so hot that it burned my hand, put in some ER, drove it around town for three months, after that 3 months there was no excess heat or noise. The trasmission lasted for another 60K before the I lost the overdrive. So, ER reduces friction extremely well, allowing for more power and less engine wear.
    8. Replace the timing belt at suggested intervals as well as other components.
    9. Use softer brake pads. The lifetime pads are very hard on the rotors and require them to be replaced. Soft pads may wear out faster but the pads are much easier and cheaper to replace and the rotors...much cheaper.
    10. Look in to BG products. If you can't get ER, use BG. There are products for every system on the car. Expecially, the MOA and 44K.
    11. Every oil change, spray off the MAF sensor with some MAF sensor cleaner. This sensor is located right after the air cleaner. It can be removed with a phillips screw driver. Just spray off the metal sensor inside...you don't have to clean the whole housing. Believe it or not, this is a HUGE maintance item!!!
    12. Keep the wheels aligned. It's worth having checked whenever you get new tires put on.

    Well, hope this helps.

    The only thing I'd really disagree with you on is Lucas-- brightstock looks good in the demo unit in the stores but can froth-- unless it behaves differently in an engine.

    The stock KUMHO tires on the 2008 Optima have a max pressure of 44psi and KIA recommends 30psi. I split the difference and run at approximately 37psi. Changing over to nitrogen to replace the air is also an added bonus to prolong the life of the tire. But the most important aspect the I have found to increase mpgs is my speed; keeping 60-65mph does decrease gas consumption.
  • mickeyrommickeyrom Posts: 936
    The recomended PSI on my 2006.5 Optima is 32 and I run them at 35PSI.I also have the Khumo tires.after 20,000 miles they still loook brand new.
  • csandstecsandste Posts: 1,866
    I took the wheel. Over to Pere Marquette State Park, back through Alton. Some urban driving but lots of country and slow Interstate. Hit almost 30 which is a lot better than my wife who usually struggles to hit 20, although her driving is usually a much higher rate of city driving.
  • csandstecsandste Posts: 1,866
    Averaged just under 30 mpg each way with at least 15 percent city driving on two tankfuls. Would probably have averaged 32-33 on a straight highway trip. Agree with Mickeyrom that city and highway mpg seem quite disparate. Shoved the transmission over into manual mode for highway-- kept if from downshifting on every grade, although it still went in and out of lockup.
