I don’t know if your Canadian or American so I will post in Metric, Imperial mpg and us mpg. 2 weeks ago on a 300km (186 miles) trip with a bit of tail wind I got 33 imperial mpg or 8.7 litres/100km or 27.5 US mpg with the cruise set at 100kph (62mph). Last week end I did the same trip but pulling a tandem wheel utility trailer about 2500 lbs with some head/cross wind, I did 25.5 imperial mpg or 11 litres/100 km or 21 US mpg. I was also going a bit faster 105kph or 65mph.
The window sticker is the same on all the 1500 Ram trucks with the eco diesel, it says for highway 8 litres/100km or 35.3 imperial mpg or 29.4 US mpg, that is not true for the Rebel because of the larger more agressive 33 inch tires, 1 inch factory lift, 3.92 axle ratio and no front end dam below the bumper.
i always reset my trip meter and reset the mpg average. All the figures above were on the truck readings, I did do the hand calculation several times and the hand calculations usually shows not as good mpg than the truck computer by around 1/2 to 1 imperial mpg,
I’ve always done that with all my vehicles, it makes me laugh or pisses me off when someone says ”my truck or car or whatever is so good on gas, I did the same trip and only used a quarter tank” how the hell do you know if it is that good on gas if you don’t know the size of the tank and how much it took to refill the tank and without resetting everything and doing the calculations.
If you go 70mph - 75mph to you find that your mpg drops significantly? I do live in Canada but comfortable with L/100km and US MPG. Thanks again for the response
