no bs fuel mileage ... ALL Generations
 

so lets get a list of hand calculated no bs mileage for your truck with given mods ...

2006 1/2 ton 4x4
5.7 stock
flowmaster dumped exhaust
3.92 gears
7" suspension lift
37x13.50x20 Toyo Mts

9.8-10.5 mpg 85% town driving i noticed a huge drop with the 37's vs the 35's there is a big weight difference between them

2001 half ton 2wd
5.2 V8
Duals
3.55 gears
17" wheels
Alot of city driving
Around 13-15 mpg

2008 1500 HEMI 4x4 (MDS)

Magnaflow muffler
Superchips programmer (MDS On)
K&N drop in filter
Valvoline full synthetic

70-80% of the day I'm in 4 wheel drive, days I'm on the main roads at cruising speed anywhere from 17 to 18.5 depending which way the wind is blowing, as well as terrain. Some times a little higher.

wow i could barely get that on a completely stock truck in 2wd @70 on a road trip is this hand calculated or what the overhead says?

2010 1500 HEMI (MDS)

Magnaflow muffler
Superchips programmer (MDS On)
Cooper Zeon 275/60/20 Tires
2/4 Drop
Bed Cover
Mobil1 full synthetic

These are the mods that somewhat contribute to my mileage. Around town I get around 13-15 and highway 18-20, if I can behave and keep it under 75. Before the 4" drop (Had 2" front lift) highway mileage was more like 17-18. I'm sure with some shorter street tires I could easily do 21-22 highway.

2005 1500 HEMI 2WD

flowmaster muffler
k&n CAI
stock 3.92's
2/4.5 drop
stock 20's - 275/65/20 firestone destination le (tires)


i get somewhere around 11.5 to 13.5 most all in town driving. depending on how i drive also :)

havent checked it lately though

OBC blows at mpg I do it myself. I think you misunderstood me. While I'm working my truck is always in 4 wheel drive so I never bother to check the mpg while in fwd. At crusing speed 60 to 65 in 2wd I can pull them numbers.

Averaged today.. Not good.
Bout half tank. Hand calculated to 13.04.
Haven't been driving that hard either..
04 RCSB
Hemi
K&N 77 Series CAI w/Amsoil dry filter

2000 Ram 1500 QC 1500
5.9 V-8
Champion plugs Taylor wires
Catback exhaust, 14x3 Filter MSD coil
Lifted, 33 inch tires, 3:55 gears
Regular gas

Gets 10-11mpg city and around 13mpg highway if run at 70mph steady. Doesn't do any better with premium, high dollar unobtanium plugs or a CAI.
It really needs a tuner and some lower gears to wake it up. MPGs are irrelevant...when I need MPGs I either drive to gf's Ranger or rent an econo box.

changed the egr valve and i'm getting about 11.5 now and when you take in affect my tire size is off throwing off the mileage gives me just a hair under 13 average ... which is pretty good imo considering .. i don't get much better on the hw though

2007 qcsb 2WD
lowered 4/6
5.7 stock
3:92 gears
gibson sport truck exahust
mobil 1 oil
Bg MOA on every oil change
Only 91 Octane

avg 16-17 almost all highway miles

Filled up today. 14.96.
Was actually happy about that. Need higher standards. :)

Mods in the signature line.....on 91 tune I get about 17.5-18.0 MPG mostly highway and some babying in the city. But I can quickly drop it to 14 by REALLY getting on the highway!

I am running 3.21 gears still, which really helps on the highway. I cruise 65 mph at 1500 rpm in mds all day!

my rpm is super low on the highway too but i kick out of mds/over-drive fairly easy with any grade or whatever with my 37's lol

99 4x4 2500 cummins auto rv275 injectors edge comp box arp head studs 60# valve springs hx40 turbo built tranny 6" lift 37's weighs 7760 with me in it and full of fuel and i can get 19 average if i drive senceable

2011 r/t
16 highway
14 in town

93 Ram250

24mpg average city/highway with a/c on

My 04 4.7L was worse than that. Best I ever got was about 14.5 highway, with 3.92 gears and 4.56 gears. That engine is a dog in the QC, and it was even 2wd!

i think i do now lol. 2002 3/4 ton rclb 4x4 5.9L 360
3" suspension plow package

I forgot bout this thread.....my 01 QCLB cummins 6sp with 4:10's only mod's are quadzilla pluse v2 straight pipe and a BHAF i get 18 average and i drive it like i stole it all the time lol it dont ever get a break

My OBC says.......Your gas mileage sucks, have fun filling up.....

My 08 qc 4.7 4wd 6 inch lift on 20s wrapped in 35s 3:92 gears got 9 in town and 12 ish on highway

3:92 is low geard for a gas truck.....my 4:10's are retarded low
This 6th gear
http://i1129.photobucket.com/albums/...9/IMAG0172.jpg

I have 4.10s in my rt

We also have taller tires and more rpms I need 4.56s in mine something terrible

And much lower geared overdrive transmissions. My 6 speed auto in the Wagon has a 0.625 6th gear. Even with 4.56 gears and 34" tires, I'm running a hair under 2000 rpm at 70mph.

And MPG sucks, I get about 9-10 in town (with my heavy foot), anywhere from 12-15 highway depending on wind speed and direction, and 9-10 towing my boat, which is about 4k lbs after everything else is loaded up.

My tires are 32.2 in tall and I run around 2200 at 75

Im guna swap for some 3:55s cuz i can only turn 3200 rpm and make enormus amounts of torque between 1800 & 2200 rpm 4:10s r useless in a cummins......i can bearly squese 100 mph out of her but she will get from 0-100 dam quick if i stand on it i can be doin 95 at the top of a on ramp easy and still get 18 mpg
