V6 Mileage frustration - looking for solutions by techman41973
Nov 09, 2008 (4:32 pm)
Reply
I have a friend who owns a 2007 Kia Rondo (6 cylinder). Him and his wife get around 16mpg in mixed city/hwy and on a recent highway trip the best they got was 19mpg. The car has about 4000 miles and the dealer hasn't been very helpfull.
I noticed a few others complaining about horrendous MPG. Has anyone found a resolution to this problem? Thanks

700 more miles on long hwy trip to/from Raleigh, NC to Aberdeen, MD. Gas mileage for entire trip just shy of 28.7 mpg. Includes some city driving in Baltimore. Car (2007 LX I-4) has 13,000 miles on her now........

I too am getting horrendous gas mileage. Bought a new 07 EX V6 in March 08.
At first got high teens in city & low 20's highway. Figured the car wasn't broken in and it would improve over time. Well now I'm lucky if I get 15 mpg in the city (don't know how much the cold weather affects mpg). Most of my driving is city.
Does Kia have a "driver habits learning curve"? ... once had a car that would adapt to your driving habits and your mileage would be effected.

and run two doses through two consecutive tanks. I have found the Rondo engine especially sensitive to carbon buildup. I am running Techron thru a tankfull every 2000 miles; my mpg spikes up each time. I have the I-4, and consistently get 28 mpg on straight interstate trips. Down to 20 in winter urban driving.....

Now at 15,300 miles on the odometer on the '07 Rondo LX I-4. Am consistently getting 24 mpg on my all-purpose (suburban driving) tankfuls. I do believe that running synthetic oil in the crankcase and using the K&N cotton/oil treated air filter helps in that regard. Long sustained hwy trip tankfuls get 28 mpg.

We bought our 07 EX V6 in August 07, and now it has 25,000 km. We are still getting 33 mpg Imperial on the highway (at 110 km/hr) with 2 adults, 2 kids, a load of cargo and running on studded winter tires. I am mighty pleased with that, considering our 98 Legacy AWD wagon with a 5 sp manual could only ever manage 32 mpg in the same conditions.
Around town, which is largely rural, our V6 Rondo gets 24-25 mpg Imperial.
Overall, I am delighted with this fuel economy.

Suggestion for establishing database for Kia Rondo fuel economy results... by smoothsailin

If case other owners may be interested, be advised that I have set up categories for Rondo owners to post their fuel economy results at www.brianbauer.org.
 
I just posted results for the first fill up since purchasing my '08 Rondo V-6 last week(25.2 mpg). Note that registration at the site is required before results may be posted. However, registration is free....and simple.
 
I've set up I-4 and V-6 categories on the site for contributors to post results for '07-'09 Rondos. After registration it only takes a minute to login and post your results for each tank. The input fields include:
 
Date
Volume of fuel (in U.S.gallons, imperial gallons, or liters)
Price (in a variety of world currencies)
Distance traveled (miles or km)
Fuel type (regular, mid-grade, premium, diesel, etc.)
 
I've been posting results obtained with my '05 Mazda3i (2.0 L manual transmission) since purchasing it in March of '05. Note that my car's results are the ones posted for Chesterfield, VA
 
As a registered contributor you can keep track of your car's overall average as well as averages based on all contributors.
 
I'm hoping other owners will consider posting their Rondo's fuel economy results for comparison at this site. So please take a look.
 
Thanks!

MPG results for 1st 2 fillups ('08 Rondo LX V6) by smoothsailin
Mar 13, 2009 (3:42 am)
Reply
#1 324.0 miles / 12.857 gal = 25.20 mpg
#2 343.8 miles / 12.894 gal = 26.66 mpg
 
Noted: the car's low fuel light came on right before the first fill up, but had not come on last night. Strangely, the tank swallowed slightly more fuel last night though.
 
May have a few more miles driven on the expressway for the last tank, but still would estimate less than 20% highway miles. Avoided short trips (say less than 10 miles) for the most part.
 
Not bad I'd say

That's better than my '07 LX 2.4L by garnermike

...typically gets from that kind of driving. Consider yourself blessed. Or being a damn good hyperdriver.......
 
If it's like mine, expect your Rondo tank to vary often between overfilling and underfilling, resulting in wide fluctuations in mpg. For example, for a tankful spent on my usually "suburban" driving, I recorded 32 mpg---a mix of overfilling that tank at the start, and then underfilling upon refueling. The next tank mpg computation---for the same sort of miles driven--- was 20.0 mpg, likely the result of that earlier underfilling and then an over-refilling. Happens to me frequent enough to notice.

I did not use many "hypermiling" techniques on the last tank and in fact I used the manumatic feature a lot to hold the lower gears and allow the engine to spin up to 3-3.5k rpm before selecting a higher gear when accelerating during the initial 600-mile break-in period. Of course, when striving to achieve maximum fuel economy I normally strive to get in high gear quickly in order to keep rpm low as low as possible w/o lugging the engine.
 
However I have been using light pressure on the throttle and braking gently, both of which are techniques that will generally contribute to superior fuel economy results. Planning to avoid short trips as much as possible also can pay fuel economy dividends based on my experience.
 
Of course with the initial 600 mile break-in period behind us I've now turned the Rondo over to the wife. So I would be (pleasantly) surprised if she manages to match my preliminary results, for she tends to have a considerably heavier foot when driving than I do, and she also tends to make far more short trips (often unnecessarily i.m.o.).
 
We'll see...
