Mileage - believe it or not...

I've been following this site for a long time and bought my 2015 longhorn 3d back in december. I now have over 10,000m on it and love the way it drives, air suspension and the mileage. I seem to average around 24-25 mpg so far and its always a mixture of hwy and city driving. I have read so many accounts of people getting 30mpg and have tried and tried to no avail. This last weekend I had a long drive on the highway of about 160 miles and lots of time to get there. I figured I would do everything possible to get the best mileage I could. I started out at 68mph and hit the reset button. I have to mention here that its very hard to drive this slow as I've always set the cruise at 75mph or so. What happend next was nothing shy of amazing. I have never seen my mileage thing go above 27? mpg but at this slower speed it started around 29-30. I watched that mileage meter and finally found the best mileage was at 59-60mph on the flats and let it slow down to 50-55 on the hills and speed up to maybe 65-70 on the downhills. With a lot of diligence on the go peddle I was able to watch the average mileage slowly count down after 160 miles to 32.7mpg. I never thought my truck could get mileage like this and always wondered how others could join the high mileage club and now I know. I believe anyone can do this but are probably like me and drive way to fast and push the go peddle way to hard and always maintain speed on hills etc. Heres the challenge - drive over 100 miles and post a picture of the best mileage you can do. I will start

7.2 L/100km = 32.7 mpg
256km = 160miles

Funny you got 7.2L. That is exactly 1 U.S. Gallon. Now you take the 100KM, which is 62 miles. Now it's really screwed up as you are not going 62 miles per gallon, are you?

Man I am both screwed up and admiring your fuel mileage, whatever it is.

You guys are too funny. I can speak both american and canadian :)
I tried to do all the conversions for you but I guess the picture has you stumped. From top to bottom here's the conversion
Canadian eh American
Distance km 256.2 160 miles
Average L/100km 7.2 32.67 mpg
Average km/h 93 58 mph
Elapsed Time 02:44:58 2 hours, 44 minutes and 58 seconds

1 Gallon of fuel is equal to 3.785 liters metric.
No offence to anyone here, but 80% of the world uses metric now, including most precision equipment made today.
Almost all of the cars, planes, and equipment built now have 100% metric fasteners.
Only the US have still not fully adapted to metric yet! However they will need metric tools to fix their cars!
Don't be afraid to learn metric, as it is not that hard to learn, and knowledge is king.
I was taught imperial measurement as a child, but quickly learned metric later on as more equipment built today uses metric measurements now.

Good luck to you. I found it best to not use the cruse and used the go peddle very gently. Post a picture after. Best if the picture is in metric so Captain can figure out the mileage for you after....

Hey, if you can move a decimal point to the left, or right, you can operate the metric system!

...and the US isn't the only country not officially metric... Burma (Myanmar) and Liberia are still using the Imperial system. <grin>

Temperature on these diesels is a factor too!
How quickly they get up to operating temperatures, where the fuel numbers begin to get good.
If you drive say 10miles the truck is just geting up to operating temps, now throw in cold temps and your tranny and engine stays in a lower gear to help warm up things! Now say a good temp around 74f and above these little diesels act much differently in my humble opinion and start showing good mpg almost 2-3 mins after driving hitting 24mpg and above sooner!

Now the truth comes out. NEVER listen to me. A liter is like a quart but a bit more. 4 quarts to a gallon makes that 7.2 = 2. I did not use common sense or had none. Used a Google calculator to get it right and that thing is wrong. Just used it again and the link I used is stupid wrong. Went to another link and it's right. I had no common sense to figure that out.

Next time I want common sense, I'll look in the refrigerator where the other Alzheimer people hide their stuff.

Thanks for the reality check.

One other thing. A liter is too small a quantity to use logically when you measure fuel. It should be a greater volume like a gallon. Like maybe a 10 liter measure called a megal.

I'm about to get an ecodiesel and I was talking to my buddy who just got one. He said he gets 1300-1500 KM's out of 100$ of diesel. Fuel here in Ontario us at 108 cents/litre. Is he bullshit ting me or is this possible?

I call B.S, unless he's driving a 2wd reg cab downhill for that distance. I've never put much more than $100 worth of fuel in my truck, a fill up from 1/8 will be just under or just over depending on price. I have never got more than 1050 on a tank, usually between 800 - 950. 1200km might be doable driving 100kph, all highway. No one is getting 1500 to a 92(?) litre tank. If you used every last drop of fuel that would equal out to 6.1L/100km, not happening.


That is the best I've got over a longer distance, probably 50/50 city/highway.


Not 100 miles, but I could have maintained it if I wasn't impatient.
