It's a "given" as well.

 

Go back and re-read the original post on a few of these mileage threads. You'll find something in common. Most start off by saying, "I recently purchased a .....". If you're new to owning a full sized truck, the mileage can be a bit of a shock, especially if you're coming from an economical car.

In the past 30 years or so, of driving full sized trucks, I can tell you. Today's trucks get great mileage. I remember when small block half tons struggled to get 10 mpg. Throw a big block in and 10 would have been something you'd dream for. Ever wonder why older trucks had dual tanks? Without them, you couldn't get too far.

 

dude i got about 3 to 6 mpg when i did my cai and duel exhaust and another 1.5 with a top so iam around 20 total mpg as long as i don't gun it or race it in my 07 4x4 supper crew. with this truck of mine i have noticed that the weather makes just as much change to my mpg as my driving habits so hope this is some help and enjoy your new truck/gas hog lol

 

I just finished my second tank of gas just doing city driving.....11.3 mpgs was the average. I drove it under 2k rpms..

I remember my 02 screw 2wd would give me the same mileage regardless of me driving it like an old person or if I drove above 2000 rmps.

 

is your truck 4x4?

 

Sorry, my sig is not being attached to my threads...here are my specs...

I honestly think as your drive your new vehicle, any new vehicle, the tires slowly wear increasing the number of revolutions per mile giving a mathematical sense of better gas mileage. Even though your not actually getting better mileage, it can be proven with some simple math.

Then we see those who buy new tires, but are disappointed that they don't get as good of mileage with the new tires as they got with the old ones.

 

green are you kidding about that come on no way is that true? dude and there is a group called men in black and area 53 is real right

 

15 - 16mpg average, 20.4mpg highway at 70mph, I love my truck

 

If you reset it everytime you fill up and actually drive around then it's pretty accurate but if you do any kind of idle time then it throws it off big time.

 

Your gas mileage will not go up. In fact it will most likely go down. Every vehicle tends to get worse mileage the older it gets.

Now, if you keep it tuned and keep the fuel injectors and filters up to snuff you'll maintain mileage, or get close to original low-mile mileage.

 

I try to keep my RPM's under 2K like other have posted and Ive been getting around 15.5 MPG's.

 

There's been alot of info on ways to improve gas mileage over the years, some practical, some not
Reduce the weight you're carrying, every 100-200 pounds of dead weight is like adding another passenger. Don't carry stuff you won't need anytime in the future.
Each engine has an rpm range where it gets the best mileage. If things like the rearend are geared to put you into that range for the most common driving situations you encounter, you'll get your best mileage for you vehicle.
I don't know how much efi can compensate, but keeping your vehicle tuned up and running at it's most efficient level should help out your mileage.
It's easier for a vehicle to stay in motion than initiate motion. If you can modulate your speed to hit traffic lights when they're green, it takes less fuel than stopping then restarting.
Drive like you have an egg between your foot and the accelerator. Slower acceleration takes less fuel to get to a given speed.
Maintain your vehicles fluid levels, works best that way
Maintain your tires air pressure. It will reduce rolling resistence which helps milesage. Use the right tires for the right driving conditions (big sticky tires consume more fuel than narrower harder tires do on city streets).
Insure things like your air filters are being kept clean.
Personally, I find I get better mileage with certain brands of fuel in my vehicles than others, even at the same octaine ratings. Don't know why, just does.
Cruise control does better than most drivers on the highway, some disagree.
Some say roll up the windows and use the AC while others say the power drain is more than the drag from opening the windows, try it and see what works for you.

This is alot of stuff I've seen, read or tried over the years. Much of it's just common sense. Try what you want and see if any of it helps you out. Understand though that a truck typically has both more rolling resistence and frontal space than most cars. All kinds of factors come into play and without spending alot of $$ redesigning, you'll probably never get as good of mileage as you want no matter what. It then becomes a matter of seeing if you can get to a level you can live with.

Good luck

blue I'm serious, it's all true. The thing to question is if it is significant enough to make a noticeable difference. If you wear your tires down 8/32 then you have lost that much on the top and bottom for a total of 16/32 or 8/16 or 4/8 or 1/2 inch. A typical F150 tire is 32". that is 1/64 of the diameter. At 16 miles per gallon the difference would be .25 miles to the gallon difference, if my math is correct.

 

Mine has been crap fromt he get go. I got right around 13 city. Then got a tuner and pretty much the same. Then went custom tunes and no difference. Had an 04 that I could get upper 14 to 15 city and I had exhuast, Air intake and tuner. The 07 doesn't have an air intake. Maybe I need one of those.
