Gas mileage question

Hey guys I just bought my first truck. It is a 2014 3.7l f150 regular cab 4x4 STX. After the weekend of driving it, it now has 440kms on it. I have to say coming from 4cyl cars all my life I was shocked when I filled the tank for the first time. 98l tank @ $1.45/l is a lot more then I am use to but I can deal with that. What really shocked me is that my Kms til empty was reading only 599kms. I was expecting for a lot better then that as my dealer told me I should get in the high 20's in MPG. So either my math is really wrong or this truck is getting no where near that. Do you guys think that these number are accurate and what I should expect or will it get better as it gets broke in?
Thanks in advance
Scott

440km isn't a fair gauge of the fuel economy. Run 3 or 4 tanks through it and average it out. Always calculate it by hand. Realistically I'd expect 20-25mpg with 100% highway driving dependant on speed. City driving I'd expect mid to high teens.

Okay that's kind of what I was thinking. Just to new to really judge yet. Thanks. Do you have an f150 with this engine?

You will need at least 10k before fair mileage will come into play. Expect crappiness for a bit.

I generally avoid using "gas mileage" and "full size pickup" in the same sentence.

For the sake of argument , and because it makes me laugh, try these numbers......

Raptor Scab, 6.2, 4.10's, 6300 lbs.......15.5L/100 km

FX4 Screw, 5.0, 3.73's, 6300 lbs........14.5L/100 km

Too lazy to do the conversion to mpg, but makes you wonder where a Raptor Screw would fall.

And yah, relevant to the original post, give it a few tanks to settle out, a lot depends on how you drive too.

Just found one of those on line mileage conversion dealios….

15.5L/100km = 18.2 mpg (Imp)

14.5L/100km = 19.5 mpg (Imp)

With 1 litre per 100 km difference, in 10,000 km I've saved about 100L of gas, so maybe $140 in 9 months. Impressive.

So, with a 3.7L Reg Cab, I would expect you should be mid 20's anyway.

Gas mileage question

Depends on hard he is on the pedal.

My '11 5.0 4x4 Supercrew I could get as low as 13l/100kms during spring/summer months.

Edit
My silver '09 5.4l 2wd supercab 3.55lsd would get me in the 11l/100kms during spring/summer, though had to very nice on pedal and this was only achieved after my upgrades.

I've got a 2012 Supercab XLT 3.7 with 3.73 gears, and 2wd, and the 98 litre tank.
l've got 42,000km on my truck, and l work out each tank of gas by hand.
I noticed the mileage improve a bit after it had about 5,000kms or so on it.
The mileage does really depend on how fast and/or how hard you push the accelerator. if l keep my speed below 110kmh (about 2,000RPM) l can get pretty decent mileage. Sure not high 20's though. Wind sure effects mileage too. I've got a high of 23mpg once with all highway driving in the summer, but with my 65% highway and 35%c city driving, l've got a lifetime average so far of 18.6MPG (U.S. gallon). My city mileage is probably in the 17MPG (U.S.) range.
I don't think that's too bad considering that includes winter weather as well.

The on board distance to empty is very much geared towards how you have been recently driving. I can see mine change with every trip that l take. if l'm driving on the highway, the distance to empty plus mileage traveled increases for a higher total. if l'm stuck in city traffic, or driving into a strong wind, the total decreases.

I think the mileage is pretty good considering it's a full size pickup.

Congrates on the new truck.

Thanks for response. I am just nearing the end of my trucks first full tank of fuel. Fuel mileage has been very good for as much as I can tell on the first tank. I'm at 820km with 92 showing til empty. I've seen my L/km down as low as 8L/100 on the hwy at 100km/h and as high as 14L/100 on an old rough dirt road I take to my fishing hole. For the most part I'm traveling in 60km to 80km zones and I'm really quite impressed with the distance I was able to get from one fill up. Initially when I filled it up it said 599 til empty which really freaked me out but after a day or so I could actually see that number improving. So far a really love this little truck!

820K's on a 98L tank is pretty darn good. Thats about what I average with my 5.4L w/3.73's and a 135L tank.
