X2 I did this and started getting 21mpg

Get a Scangage or Ultragage to watch your instantaneous mileage. That will take care of the driving habits side of things.
A dirty MAF sensor could also be the culprit from the K&N. Before you replace the K&N I would clean the MAF sensor and see if the mileage goes up. It may have been the initial oiling that got it dirty.
Most of the time it seems like the bed caps are roughly break even on mileage, so I doubt that is dropping you 5mpg.

Take that stupid K&N filter out, they are junk! Drive it for a few tanks and then report back.

Agree... but if most folks in a 4 cyl. Taco get 20-25 mpg, you got to wonder why he is only getting 15 mpg, right? 15 mpg is all I get if I am doing only city (stop and go) driving... but I have a double cab 4WD V-6. Once I get on the highway and cruise... my mileage instantly improves to 17-19 mpg.

With all due respect, I don't have to wonder why he is getting 15MPG. I usually don't read MPG threads or concern myself with fuel economy on my truck but I mis-posted so I had to offer something.

There are too many variables to troubleshoot fuel economy inconsistencies in any fueled engine. Weather conditions, Altitude, Geographic terrain, Driving habits, Tire pressure, road conditions, Acceleration, Stop and go incidence, braking, trip distances. I would bet those who live in San Francisco replace brakes more often and get worse fuel economy than one who lives in Texas.

Fuel economy is a very sticky subject with too many variables. KIA is getting sued for misrepresenting theirs. In any case my "advice" would be to take it to someone who fixes these for a livelihood, If there is a legitimate cause and effect, a mechanic will find it in these computerized vehicles using error logging. Anything other than that has to be habitual or environmental.

I can drive and get 12-14 or 20 w/ a 4WD. All depends on the pressure I put on the pedal....

I think its the traffic man. I get 12-13 mpg with my V6. Spend 90% of my time driving in and around the city.

You are in Boston Mass. Everyone's mpg goes to crap in the winter, even hybrids and electrics. The K&N was probably a bad call if you are concerned about MPG. Keep in mind, more cold dense air means the computer has to add more fuel to maintain the air-fuel mixture. You probably spend more time warming up your truck and idling too. Boston Traffic... Do I even need to say it!? Wicked retădded. Add that to the crappy winter blend gasohol and presto... Crappy MPG.

I'm not swapping my k and n, I just dropped 60 bucks, and I never heard of it hurting gas. I don't know how to check odometer with tires spinning but judging on going to work in my f150 as compared to my new Tacoma the f150 is doing the same if not better then this 4cyl. In hindsight, I should have bought the V6...shame on me for wanting to save on gas. I could care less about power. Right now, I just feel like telling toyota to take it back and give me the bigger motor.

Thanks for all the help and insight.

Went out to Central Mass tonight and had some positive results. The only mods I did was remove the charcoal secondary filter and added a K and N Filter. I filled up with sunoco 94 @ 4.00 bucks a gallon. I also checked the tire pressure and made it 30 psi. I drove 133.7 miles on 6.53 gallons for a an average of 20.47 MPG. It was about 50% highway. This is the best I got so far. I don't know if it was playing with the filters or sunoco 94 or tire PSI....Now it's back to city driving for about 60% of the upcoming work week. I will report back with averages.

K&N air filters are not that bad I used one in my old Camry and it got great mileage with it plus it all depends on how heavy you oil it

Your I4 does not benefit from higher octane, waste of money.

It also doesn't benefit from any intake mods for mpg.

What was the tire pressure? That's the 1 thing you mentioned that certainly was hurting you if low. Try even higher than 30 psi.

Highway driving is always good for mpg, at legal speeds.

Topper usually makes it worse.
