I convert kms to miles and liters to gallons (US). The metric equivalent to mpgs is liters/100kms, either or I can do but I convert it for the sake that a huge majority of fte users are amerincan.
The math is very basic:
liters x .26 = gallons
kms x .6 = miles
miles / gallons = mpg
My calculations were slightly off where I thought our tanks had a 90 liter (23.5 gallons)capacity, but according to the internet we have a 25 gallon tank so my mpgs decreases to 18.5.....still pretty good.

You sure have done a lot of recalculation. Curious how the size of your gas tank enters into it? MPG is measured by the amount of gas used over distance & has nothing to do with how big the tank is. MPG would be the same if you ran off of a 5 gallon gas can sitting in the bed.
Presume you're discussing a short bed/short wheel base? Think the regular length has a 30 gallon tank. If this is the case are you going to need to revise your MPG down to 15.4 from "the amazing 20 mpg......?"
Also presume you've confirmed your odometer's adjustment, to compensate for oversized tires, against interstate mileage markers? GPS can also be helpful to check for both speed & mileage accuracy.
Have had discussions with folks who relied on some of the notoriously innaccurate onboard MPG indicators & claimed absurd economy.

excellent point. also for us canucks lets remember that there are 3.7 liters in a gal and 1.6 km's in a mile.
96sherm if your getting that, please tell me how. im very honest, i want to get that mileage if i can.
king i seem to mirror your results over the long term.

4.546 litres in a canadian gallon, therefore my calculations end up a tad higher. i'm in canada, so i'll use the canadian gallon, no offense meant!! my driving style is smooth for the most part, my truck is listed in my sig, very few mods. terrain is very flat. the other thing is...why would a guy lie about his mileage?? you're fooling no one but yourself...

we...our trucks are very different for starters, i would think that your biggest killer is 4x4 and the 5.4L engine. those 2 alone are a recipe for lower mileage in some cases. my only mods are k&n filter, duals-the cats, and i made a tonneau. of the 3 things i've done, the tonneau made the biggest difference. another thing to factor in is the altitude. i'm thinking that sask is a whole pile higher than NS, making the air thinner, this burning cleaner/leaner. i know that comming from NL i notice a big difference in how vehicles run due to this.

Why do I need a GPS to argue my point with you? How do I confirm to you that I made adjustments to the odometer?
To answer your question I have yet to recieve any codes for my adjustment to the computer....and yes, before you have a frantic post to question me about that, it does exist.Are we done yet???

I did & saw 3 different MPG figures. Also noticed that you had to recalculate your MPG based on finding out the true size of your tank & was puzzled.
The 8' bed, long WB F-150 specs in front of me indicate a 30 gal tank. You seemed unsure of the size of your tank. Just trying to help, have not seen your truck & checking odometer readings by use of interstate mileage markers can help you confirm your "tuner" was adjusted correctly.
You do not need to confirm tank capacity, only fuel used & miles driven.
You do not need to confirm you "made adjustments to the odometer" you need to confirm the adjustments you made were accurate.
We're done, unless you want to recalculate a 4th time.

How often do you see a scab long box????? Your giving a spec of a vehicle that basically few have, and now your presumption is that everyone has one is a very weak argument.
The 20 mpg was rounded from 19.7 so no re-calculation there, I made an error in the tank capacity re-calculated, so it was only one time. If you would back track and read the posts carefully, you wouldn't be shooting your mouth off so much.
So now I have to take pictures of receipts, sticker tags, and my tuner making the proper adjustments to my truck to prove my point??? Can you say **** retentive.
Anything else Boss?!

lol wind blowing hard now...
maybe your just getting a better quality fuel 96sherm. the higher the alt the less dense the air charge. less dense air equals less efficient combustion. i hope my 4x4 isnt the killer but maybe thats what it is. i have a cap (flush) on my screw but i didnt see any difference better or worse. has your truck been reprogramed?
you'd be surprised what i would pay to get close to 20mpg.... lol

no reprogramming, no tuner(yet). just a 2wd 4.6l auto s'crew. it runs like a dream, and i drive it like a gold brick. maybe i've just gotten lucky? i only buy my fuel at superstore, use the regular.
do you have an extra set of oilskins i could borrow for a bit?? think i'm getting wet here...
off topic, Beer boy, how do you like your tuner??
