OH really? I just got it again this weekend going down to the beach. Screen says ~22 calculated is about 21ish.
Just removed Hydrocarbon filter

well Im getting the same, but Ive still got stock tires, lol
February 15th (cool air). Trip = 845 miles. From: Raleigh NC to Chicago. Load: Moving to chicago, truck was packed to the ceiling. MPG computer read out at the end of the trip = 19.7. I have my filter in place.
Given the fact that we had to go up and down the mountains through Western Carolina, West Virginia, Virginia, and into Kentucky, and still ended the trip with that mpg, I certainly believe the 22mpg rating if the filter was removed, and I doubt they were as loaded down as we were during that move.

Downhill all the way?? With a tailwind?
Sorry, not buying it. EPA says 21 I think, and it goes down about 3-4 mpg per 5mph over 60.
22 mpg at 55 mph maybe.
Not at 80.

LOLOLOL why are you even debating me? You have no idea what mileage I'm getting. EPA also says a lot of other things that are BS.
So your saying at 70mph im going to get 8 less mpg than 60 - that makes no sense at all unless you drive a Model T. Sorry your input is worthless at this point. KThxBye

Since you claim to be studying to be an M.E. while living with mommy, you may want to start thinking like one. Readily available DATA (not arrogant post high schooler's opinion) indicates that fuel mileage drops off quickly over the speed of 60 mph. One example is here, which clearly shows that MPG decreases with speed in the range posted by George. http://www.fueleconomy.gov/feg/driveHabits.shtml
Because you obviously flunked or haven't taken fluid dynamics, I will remind you that the resistance of a body moving through a fluid (like air) does not increase proportionally, but rather with the square of the velocity.

Havent got to fluids yet. I agree with you that the relationship is not linear and is in fact parabolic; however, you have not taken into account efficiency of the engine at all. Saying that EVERY car is most efficient at 60mph is a silly statement. Cars are designed for different things, some perform better at 100+ and others below 25. The V8 loves the 2250-2500rpm mark and that is where I find the best mileage is while still maintaining highway speeds (65+). You have to keep in mind that the relationship between RPM and efficiency is not linear let alone positive at all intervals.
BTW I'm minoring in Aerospace Engineering and plan on getting a masters in aerospace, aeronautical, or explosives engineering as well. 3.3GPA at a top-tier engineering school FYI. Im going to be a Junior so my specialized class experience is little; however, I plan on learning a great deal this year.
My comment was only taken as arrogant. To say that I get 8mpg worse at 70mph is a sever overstatement.

I'm always amazed to see how much the numbers can swing when people compare their MPG.
People need to keep in mind there are so many variables though.
Air filter type? Is it clean?
Tires size and tread. What PSI?
Hydrocarbin filter still inplace?
Flat terrain or hills?
What speed were you going?
Windows down? A/C on?
Having done plenty of driving with the truck before and after I removed the hydrocarbin filter I can say FOR SURE it was worth a solid .5-1 MPG increase when driving at 70 MPH on the highway.
The truck MPG display used to almost always show an average of about 19.6 when cruzing at 70 for a few hours. Now it shows an average of 20.5 almost every single time after being on the highway for a few hours. Calculating my own MPG I end up with just over 20mpg almost every single time I go on a highway trip as long as my speed was around 70mph. I'm sure that could be improved with some tires with a less agressive tread pattern.
Driving factors: Windows Up, A/C on, clean OEM Toyota air filter, no hydrocarbin filter, Mobil 1 5-W30 oil, Revos (stock size at 34 PSI), mostly flat terrain, 95% 70 MPH.

Just a question...
This topic caught my eye and what evolved from the topic about those that are eco friendly, or performance seeking. I like the two extreams, being a raised libral from Oregon, yet I'm in the Marines voting Republican and flying President Bush around on Marine One. I don't have an answer on which side wins, its my never ending battle. I digress.
On all of the "who's getting what for fuel economy" is anyone using cruise control where the other person is not? I refuse to use the cruise control if and when I am concerned for MPG (like climbing Mtn passes). I drive my 4runner all the time from Portland to San Diego. First time used the cruise control, looking at 16.9 UP IN THE MOUNTAINS, lower Oregon, upper Cali. I disengaged the cruise and I went up to 19.7. Once I was between LA and San Diego right at Sea Level and out of traffic did I see over 20 MPG. Over 75 MPH and I would agree over time your MPG will start to decrease. Its not an instant decrease, but time/distance over 75 MPH and I see a decrease, IN MY 4runner.
Because I'm stationed in Cali, and you have to get CARB inspected for Base stickers, I plan on keeping mine in, until I get a CAI.

I just took a 800 mile round trip and I definitely noticed an increase in power around the 2k rpm range whilr driving 70-80mph. The power seemed more readily available and I still got around 20mpg for the whole trip, an increase of around 2mpg. I had also changed the diff/transfer case fluid to amsoil so I'm sure that helped with the increase also.

I would really like to see what you would get if you had the HC Filter removed, and the deckplate mod. It seems to me that would give you the most bang for your buck. Based on how restrictive the filter is, removing it, and adding a $10 boat part. Its been 4running in my mind. Grrr all this talk of mods that I want to do, being in Iraq, and flying over terrain wishing I had my 4runner to play with. Boo.

Agree. I have the V-8 and I run 79 on a 70 MPH highway and the best I can get is 19.

So you got 22 MPG at 80-85 and then got 13 MPG at 90 so that is a decrese of 9 MPG by moving at 5 MPH faster. So your saying you drive a model T.

I get about 3 mpg better with non ethonol gas on the highway.
