That's great mileage from the 6.4L...Don't recall seeing a seven as the second digit on mine!

Agree, I had an app when I first got the truck and was gonna be religious about putting the info in for it to calculate for me. Filled her up for the third time and stopped inputting the info.

I use an app. I put mileage, gallons, etc in and it tracks MPG and costs over time.

What app,I ordered a 22 and am curious,I'm sure it will be better than my old V10

This is what I was using when I had an Android phone. I need to find an iphone replacement, looks like there are a ton of options though.

it is what it is.

FWIW...

Drove last weekend from Tampa Bay to Miami and back.
75mph both ways, head wind on the way down
87 octane Costco gas

EVIC was 1mpg optimistic on both counts.

13.72 mpg on the way down
15.85 mpg on the way back

So, always drive facing north for best MPG

I use aCar, it also will sync right up to fuelly for you and then everyone on the forum can know what you're mileage is.

That seems to apply here in WI too. I always get better mileage on I94 heading west (which is really more north than west in this section) than east.

13.9 per the lie o meter; 12.8 mpg hand calc. I did mix in about 20 miles of towing (<50mph). Topped off with 87octane (instead of 91 - Costco) this time to see if there is any difference.

Highway or mix?

 

[raven_dt]

70/30 mix, hwy/city

 

[raven_dt]

Updated @ 1800 miles: 13.3mpg, 87 octane, 70/30 mix...not good.
Edit: hand calculated

I mean, you basically own a tank. So, 13.3 sounds normal to me.

The mpg you are seeing is well within the real world averages of the 6.4 Hemi in the HD. This shouldn’t come as a surprise.

Even back in 2014 with the 6sp Auto the mpg was similar.
