Hi, I have a 2019 Ram 1500 laramie longhorn. After every fill up, with the truck sitting still, the gas mileage shows I am getting 4.7 mpg. But, I am not moving at all. Shouldn't this read 0 mpg?

It does read "0" on my '18 when stopped...Hi, I have a 2019 Ram 1500 laramie longhorn. After every fill up, with the truck sitting still, the gas mileage shows I am getting 4.7 mpg. But, I am not moving at all. Shouldn't this read 0 mpg?
Agree, my 2021 Ram and the Grand Cherokee both read zero when I am stopped.It does read "0" on my '18 when stopped...

Need to retake your math class. Mine is accurate to within 2 or 3% most of the time. 10% on 15 mpg would put you out 1.5So, to confirm, the ECO mpg calculation is relatively accurate to within say 10% or so?
That’s what I wanted to know. I was being generous with the 10% tolerance. So your experience is 2-3%. It’s that accurate. Neat! So the 27+ mpg that I was getting on our short trip was amazing. Great…..Need to retake your math class. Mine is accurate to within 2 or 3% most of the time. 10% on 15 mpg would put you out 1.5
I approached that when I had my old 91 D250/Cummins with the 5 speed manual. I could get 25 if I tickled the go pedal or 24 if I hammered it.I might suggest that if you’re reading 4.7 mpg when stopped that the 27 mpg may possibly be 4-5 mpg too high. Actually that would make sense because I never owned a truck that got 27 mpg…even an older diesel or a mini truck with a four cylinder
I’m not the OP and hadn't noticed that particular problem with my truck. I did notice, as I posted earlier, that on a short hi way trip on flat open road using CC, we were indicating 27+ mpg, which I thought was suspect. Just wanted to hear what others were thinking about the systems accuracy.I might suggest that if you’re reading 4.7 mpg when stopped that the 27 mpg may possibly be 4-5 mpg too high.

Is that the display showing or is it the trip meter telling you that.Hi, I have a 2019 Ram 1500 laramie longhorn. After every fill up, with the truck sitting still, the gas mileage shows I am getting 4.7 mpg. But, I am not moving at all. Shouldn't this read 0 mpg?
