I'm looking forward to another "Rocky Mountain Road Trip" the week of the 4th with my son. It's our yearly vacation together, just putting on some (s)miles as we cruise a variety of roads, and suck it all in.


I'll reset the "trip A" and see what we get for the entire trip this time, but on the last couple of trips with the Scat Pack in Sport mode all the time, we got between 25-26 mpg for the entire trip, which was about 2k (s)miles.


I've been very pleased with the 392's trip mileage, running on all eight, all the time, and plan on doing it this way again.

Yes. Fluctuates between 50-55 depending on the zone, I don't like to speed more than 5mph off the highway.

I typically average around 19.5-21 mpg with mostly hwy driving . I also go from 1st to 3rd to 5th while driving in the city. These cars get crazy mpg considering what’s under the hood, but if you put your foot down they will GUZZLE 93 octane like a frat boy does cheap beer.

I was just about to broach this subject when I saw this thread. Last week we set out on our first somewhat lengthy ride. I planned on using this to check gas mileage. Here's the detail:

2018 SRT, M-6 transmission, and 3,600 miles on the odometer.
1,202 mile trip, San Diego, Sacramento, Sierras and back to San Diego
Best guess 80% freeway at 75-80, 10% city and 10% mountain

The car's computer gave me 24.1 mpg, but when I added up my gas purchases and factored in mileage I came up with 24.7.

All things considered I think this is pretty damn good for a car that weighs what an SRT does and is powered the way it is. Checking previous posts this doesn't seem all that unusual.

Ha... surprised to see this SRT gas mileage thread pop up again. I took a recent 900 mile trip and wanted to see what she could do. I set the cruise for 64 and just left it there. After one complete tank of gas it registered 30.8mpg

Now I know what I didn't know 9 months ago when I started this thread: that my SRT 392 can get this kind of mileage on the highway, and that I can routinely get 20 around town.

My T/A 392 gets about the same. I do some city driving which puts a huge dent in MPG, but I commute 40 miles each way to work so that MPG is way higher.

Really??? 20 in the city. I get in the 14s. NO highway. That's where one saves. I firmly believe you save everywhere!
Hahaha. Then again I don't go anywhere, so...

You get 14 mpg... Since I had the privilege of riding with you one day, I'm surprised you can get that much
