Well there's definitely something wrong with your vehicle or your driving. We basically have the same vehicle and I'm getting 15.3.

are you just letting the truck computer do the millage or are you figuring it out yourself manually?

Truck computer calculations are very accurate. Maybe manual calculations will give me a little better number

It depends on various factors. Winter fuel, extreme cold, city driving, full time 4wd, mds off etc.

Thread 'MPG computer lies - badly!'

Jul 15, 2019

First, this thread is NOT about the absolutely atrocious mileage I'm getting. There are already enough threads on the Hemi's bad mileage.

This is about how the computer that displays my fuel economy is lying. Lying like a rug! Liar, liar, pants on fire!

I've got about 1050 miles on my new truck. I have been tracking the mileage using Fuelly since I filled it up when I first got it home. It had about 220 miles on the clock then, so Fuelly says I have been tracking fuel economy for 813 miles, so far.

Whenever I fill up, I reset Trip B, AND I reset the Fuel Economy display in the EVIC...

I Drive 52 miles a day round trip for work, 2020 1500 laramie short box, 5.7, 3.92, MDS always off, Bridgestone blizzak tires @36psi I average 14.5mpg. That with probably 85% 2wd, 10% 4wd and 5% auto 4wd

Boy I'm at about 10.5 and that driving like a old lady.

I have a 2020 5.7 hemi with 3.92 gearing, blizzaks in stock 18” size. I’m driving about 10 miles in the city each way on my commute, pretty much no highway. Temperature here is about 10-20F. I’m getting about 12-13 mpg. Even my wife’s outback gets around 16-17 mpg in these conditions.
I notice that temperature is a huge factor with fuel consumption. When it gets cold to -10F, I get significantly less mileage. So I think it’s expected if you deal with -35F and run oversized tires.
