I've been getting 19 mpg all summer and recently got 18 (for the entire trip; 3,700 miles) towing a tent trailer to Utah from MN and back. And mine is a 4x4.

 

I was referring to your statement "I want to know how the heck he is getting 21 mpg." I wasn't taking exception to your calculations, I was pointing out that the member that started the thread based his 21mpg claim on distance traveled on his 20 gallon tank. I redid his math using the proper tank size (25 gallons converted to 94.75 Liters) giving him a more accurate 17.9mpg.

 

I have had the truck empty lots of times and have never been able to get more then 80 liters into it, how many tank sizes are there?

 

There are, or were in 97-98 models (I have a '98 and the book for it) 4 tank sizes:

24.5 gallons-Standard on F150 4X4
25.0 gallons-Standard on F150 2wd reg and supercab
26.0 gallons-Standard on Expy 2wd w/o air suspension
30.0 gallons-Standard on Long bed F150, 2wd Expy with air suspension and Expys with 4X4.

At least that's what the book says.

 

I've never replaced my Fuel Filter on my 2000. Every when should the fuel filter be replaced?

BTW, getting like 12-13MPG

 

I got 16.6 MPG on the 2nd fill up on the new truck.

 

I've never calculated my mpg. But I do get great gas milage. I'm guessing 17-18 mpg mixed city/highway.

 

Oh, my mistake. I got defensive, sorry about that.

 

i got 253 miles on my last fill up. how many MPG is that?

 

10-12 mpg Erick

 

wtf thats whack man!

 

There isn't enough information. You could have had 2,3,5 gallons left when you filled up.

I can get in between 410 and 460 miles before my low feul light comes on. depending on how I drive. I do a lot of highway miles due to my job.

 

well today i filled up with 30$ and the tank still had a little less than a 1/4 left and the odometer read 257. i couldve gotten to 300.

 

I really have to question how some of you are getting these numbers. If you have a 25 gallon tank and drive 450 miles before you have to fill up, dividing 450 by 25 is not an accurate equation. You need to know how many gallons of fuel you had to begin with and how much you used in X amount of miles.

To have an accurate number, you need to begin with a full tank and reset your trip odometer. Then, at your next fill up, notice how many gallons are required to refill your tank and divide your mileage traveled by the amount of gallons used. What's really amusing is that the formula is printed in your owner's manual

Example: Last week, starting with a full tank, I traveled 158.8 miles. Today, it required 9.57 gallons of fuel to refill my fuel tank.

158.8/9.57=16.59 MPG
