I have 1,400 miles on an all stock SRT 10, and I consistently get 10.2 mpg. I guess I consistently drive with the same mix of 80% highway at 70 mph, and 20% dogging it. Doesn't 10.2 mpg seem too low? Many other posts indicate a much higher mpg on highway use.

When doing regular driving what are you shift points? how much throttle are you giving it? I usually give very slight throttle, and shift it in about 2 seconds of getting the clutch out, and do this til 5th gear at about 35 to 40 MPH, then into 6th at anything over 50 MPH. in city driving I am getting 13 to 14.5 MPG. this is actual MPG not going by what the overhead display says.

I am using a little more rpm through the gears than you indicate that you use. But not too much more. For instance, I do not ususally shift to sixth untill I hit 60. I have ran several tanks of gas through without any dogging it, and mileage does not improve more than a few tenths. However, the truck does run very good when I do punch it. I took delivery in June 04. Could the production date have anything to do with programed engine hp and consequently, mpg? My truck will outrun stock lightnings consistently (although it is very close).

That city driving kills the MPG. Sounds like you shift at 3000 rpm or higher. My guess is I get 8-9 MPG city and 14-15 MPG highway. I average 11 mpg.

I,m getting 9.5 mpg average around town. I like to keep the rpms high though. The truck reallyy takes off when you are above 3000 rpm, plus when you back off the gas you get that lovely rumble/popping noise!!

an 8.3L V10 isnt a mileage truck

My SRT-10 isn't a daily driver so who cares about the mpg? It's a blast and it goes like a raped ape! I did not buy it for gas mileage. I bought it for fun and relaxation. I drive two Hemi Rams (not at the same time) for daily drivers and get 12.5 to 14.0. At a $1.85 gal right now that matters.

14 to 15.3 mpg for me with 1200 miles on the truck. Most miles are smooth, country highway miles with no stop lights. I shift at 2,800 - 3,000 rpm's and use the overdrive gear at 60 mph.

I know the SRT 10 is not a high mpg vehicle, and I certainly did not buy it for economy. However, I can't get 14 mpg no matter how conservatively I drive, and since I keep reading threds where other owners state the great mpg they get on the highway, that makes me wonder if I am the only SRT 10 owner that does not get any better than 10 mpg (even at a constant 70 mph on highway cruising).

Just drove my truck to Temecula to drop off at WestCoast Viper. Filled up just before getting on the Freeway. Running at 80-95 all the way for 65 miles I got 15.4 MPG. Lots of up and down hills. Overall I get in the 11-12.5 range consistantly.

If you want to increase your mileage, you have to have a light foot and keep the RPM's down. This engine will pull from 1,200rpms, so you really don't have to rev it any higher than 1,700-1,800rpms to upshift.

I was using my truck as a daily driver and normally I got around 11.5mpg, but when I drove it like I described above I got 13.5+/-.

Doesn't matter anymore though, because now that I bought my Focus I do 22mpg. And that's runnin' the poop outta it! Not to mention the little SOB is a blast to drive! Handes and brakes like a MoFo!! (Nothing to do with Larry )

I've found that keeping rpm up around 1700 rpm in 6th has given me the best mpg. That is 95mph and I was averaging 20 mpg and that included some driving in city. Tonneau cover and cruise but that was the results after 10000 mile on the srt 10. I double checked my numbers because I fill before and after and I made sure it was filled right up each time. Maybe more miles on your unit and you'll see the increase, too.

What octane of pertrol are you using?
I just got my truck a month ago and I have 1,350 miles on it. I get between 8.3 and 13.4mpg depending on how i drive and where I drive, of course.
Take the truck for a distant freeway drive, somewhere far and enjoy the looks-stares others guve you..as you get to your destination, hopefully you should see an improvement in the mpg..
N-joy!
