Mods: -Lap3 Uncle Chip -K&N short ram intake -HKS Spark Plugs -Add1 OCC -HKS BOV Originally I had the chip set to 91 octane-...

    I have a 2012 Optima SX with a little over 46k, 5w20 synthetic oil per 7500, drive average yet I typically average 28-29 miles interstate driving. My predecessor (03 Accord V6 coupe) averaged 27 mpg highway driving. I set up a appointment with the dealer but I'm thinking I'm wasting my time...
  3. 3rd Generation Optima (2011 - 2015)
    I recently purchased a certified pre owned 2011 kia optima ex. I absolutely love the car except one thing. According to the built in trip computer thing, i am getting an average of 16 mpg... is this normal? I am mostly city driving. Almost all. But the estimated numbers for that are 24. Can...

    Hyundai owners are estimated at $353 on average, while Kia owners would get significantly more at $667 on average. The company will take into account any previous reimbursement and subtract from the lump sum payment. Owners can also choose a dealership credit good for 150 percent of the lump sum...
  5. 3rd Generation Optima (2011 - 2015)
    Hey guys. I am trying to gather some data on the F/E of the 2.4. I post on another board that is mid size sedan specific, and I of course promote the Optima, because I love mine. I am looking for average mileage, and mitigating info such as living in a city, congested commute, or just the...

    Just wondering what pressure everyone sets their Winter Tire Pressure at to maximize fuel economy.

    Noticed something today - aside from the lowered HP ratings for the 2.4L, the MPG has been lowered for both normally aspirated and turbo engines. 2014 Kia Optima - Features & Specs The carryover 2.0L Theta II turbo now has 24 MPG combined, which seems inline with what most of us seem to be...
  8. Engine and Technical Discussion
    hi, guys. lately i've been having concerns about the fuel consumption of my car. since it's a 2.4-liter engine, i'm quite aware that it consumes more gasoline than my previous car, which had a 1.8-liter engine. and i'm also starting to have doubts about the car's Eco button. i just would like to...

    My main goal for this thread is for all of us to share tips and tricks to learn how to get the most MPGs. Since we don't really have a thread about what we can get our own Optima hybrids MPGs to, I thought this would be a good idea. I think the best way to handle this so far would be to post...
  10. 3rd Generation Optima (2011 - 2015)
    Just completed a trip from Canberra to Cairns and back again. Canberra ACT to Cairns North QLD - Google Maps In addition to the 2600Km (1600 mile) trip each way we covered around 1400km of sightseeing in the 12 days away. The figures below are from the trip computer only and are on a per tank...

    I have my eyes set on an Injen Intake in the future; for those who have it installed, how has you fuel economy been affected? Also, is it worth getting a Hydroshield also (I live in southeast TX, so it doesn't rain much, much less flood)?

    I noticed in the menu on our cars you can have the Fuel Economy gauge automatically reset or manually reset it.. at what point does it automatically reset? Every time you start the car?
  13. 3rd Generation Optima (2011 - 2015)
    Hey everyone, i purchased a 2012 ex turbo demo about a week ago and I'm getting awful fuel economy. I've only really done city driving and I've been driving pretty calmly I'd say and still I'm averaging 17 liter/100km (1 mpg = 2.32 l/100km I believe). Am I alone here????
  14. 3rd Generation Optima (2011 - 2015)
    Something I posted over at turbosonata.com.... Took my Kia Optima out on a 55 mile, flat highway drive last Sunday. Filled up before the trip, filled up at the end of the all-hwy 55 mile jaunt. Computer said 35.6mpg, my old school calculation showed 34.6 actual mpg. Since I bought it...
  15. 3rd Generation Optima (2011 - 2015)
    Yes, I did a search and didn't find any threads pertaining to this particular scenario... OK, disclaimer aside, I have a 2013 SX and my friend recently bought a 2013 SXL, both with the 2.0 Turbo engines. We both drive a mix of highway/local roads, go light on the accelerator pedal, and usually...

    Ok so i filled up my tank not this past sunday but the sunday before. It is pretty much a mix of city and highway driving. When i filled up before pulling out of the gas station it said 449miles to empty. I have since driven 237 miles and have 2 "bars" left on the gas gauge. It says now 46 miles...
  17. 3rd Generation Optima (2011 - 2015)
    question for the masses when sitting at idle (ie red light) my install fuel economy tops right out - should it not be the other way around ??
