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
Amsoil 5/20
Superchip 3815 set to 87 I think
305/50/20 Coopers

2004 Ram 1500 4.7L 2wd

Mobile 1 Full Synthetic Extended Performance Oil
Pulstar Iridium Plugs
K&N Super77 CAI
Airaid TBS
Superchips Cortex 91 Octane Performance Tune and 91 Octane Gas
Custom Exhaust w/ Single-in Dual-out Flowmaster 40 Series and Hi-flow Cats.
2" drop Shackles
Stock 20's on Nitto 420S 305/50/20r

Mostly Highway w/ Light city driving on the weekends avg 13.3mpg

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.
