MPGs

[88kevina]

At what rpm is the 7.3 most efficient?

[Dasaliac03]

ive always wondered the same thing

id guess the lower the better

for me, 70mph highway at 2000rpm is what i usually try to stay at, that will usually do me about 24mpg. From here to the beach its mostly flat though

yup in overdrive its 70mph at 2k rpm and without overdrive its 50mph is 2k rpm. im getting 19 highway with nothing more than an exhuast at the moment

I'd concur 1800-2k rpm's i get great mpg unloaded and 14.5 towing 2 horses in a lil trailer(bout 5k). not bad i'd say.

Damn. You guys using any additives? I get 17 empty @ 70. But I'm 4wd with 4.11s. Towing our little TT (~4500 pounds) I'd get anywhere from 11-12mpg. I am chipped, but supposedly the Bill's DD and tow tunes net you better MPG

1800 seems to be about the best cruising RPMs (keeps the boost and EGT #s low), but it's too slow. I know that at 72 MPH/2000 RPM I will average 18 MPG, but if I bump it up to 75 MPH, I will get 15 MPG. Tried that on many trips.

I drive 80mph at 2400 rpm consistently and get 16 mpg. I'm stock w/flow throw muffler.

im only getting 16.5 not towing and "4" mbrp dual exhaust how are you guys getting such great mileage

I got 14.5 mpg running 80 (2300 rpm) with a 30 mph cross wind and the AC on max (it was 105 degrees) Not too terrible.
