Cant find reason for bad mpg

[waleed]

On my 2013 kia rio, I get only about 18-24 mpg in the city and 28-32 on the highway. I checked the spark plug gap and they were all at about 0.040″. I hesitantly cleaned the throttle body, and it also had no effect. There is also no maf sensor on the intake.

In a perfect world ….
Advertised: Up to 29 city / 37 highway
Now factor in your,
Driving conditions
Driving habits
Weight load
Vehicle maintenance

Your numbers are not out of the norm.

Do you think swapping out the plugs with a new set will help?

As I stated prior..
Beyond that, you can try.
You’d probably do better placing an egg under the gas pedal
