2013 Kia Rio with terrible gas mileage?

Asked by Aug 25, 2015 at 12:48 PM about the 2013 Kia Rio LX

Question type: Maintenance & Repair

I recently bought a 2013 Kia Rio
sedan 4d from a car rental location in
Burien, WA. It had roughly 49k miles
on the odometer and i bought it
because i heard it had good gas
mileage. But as soon as i bought it i
noticed that after filling up the tank 3
days ago, i've used up about almost
half. I travel roughly 20 miles a day.
I'm wondering if i'm just being overly
critical or there really is a problem. I
need opinions and knowledge from
people who actually know a thin or
two about cars.

next fill up top it off and not the mileage..drive it for a half a tank and top off again and do the math and check back here...depending on the shape of tank..some will stay up full for a long while and others will stay on e-half a long while....>>>> http://www.folgerkia.com/kia-fuel-economy.html

Does the car seem to "Bog down" when you accelerate? The easiest thing to do is to remove the air filter to access the MAF sensor ... they get dirty and can cause bad performance/gas mileage. A spray is available at most auto supplies


and check the air filter,is it new/clean.. if mileage is not up to the specks..i sent you then like tom said is the next step..

No performance issues. I do hear a rattling sound at random moments while driving. Most usually when i'm accelerating.

Also. I've had the eco mode on the entire time since i last topped it off 3days ago.

My 2013 Kia Rio is hard on gas what will cause this
