Happy with my new mpg

Just wanna share my new mpg:
2009 Limited, stock no mods, with 36k miles.
Was 13:14 mpg city, maximum of 17 mpg highway.
I did the following:
1- oil & filter change.
2- air filter change.
3- spark plugs change.
No noticeable more mpg, then:
1- Throttle body clean.
2- injector cleaner into 3/4 fuel tank.
Now:
15:17 mpg city & 20 : 22 mpg highway
Happy with it

throttle body clean eh, I need to look into that. My spark plug change+injector cleaner was disappointing on the MPG side.

Stock type paper works best, K&N waste of money and actually lets more dirt in

Gotcha. By stock, does it have to be the paper type specifically from a dealer, or just the paper type that fits your vehicle from any local auto store.

An auto store will have the correct filter to fit your Jeep

I like my K&N drop in. If it's properly cleaned and oiled, no problem

Yep, had one ( K&N) for over 20,000 miles, and yes properly cleaned oiled etc ( ran them on some older 4 wheel drives ) , better mileage and less dirt in the tube when I swapped back to stock filter
