Spokes Posted March 11, 2009 Posted March 11, 2009 what kinda MPG do u get with ur comanches? i get 11.35 on 31x10.5! :idea:
ComancheKid45 Posted March 11, 2009 Posted March 11, 2009 I'm usually between 9-13....this is mainly just driving around town
dasbulliwagen Posted March 11, 2009 Posted March 11, 2009 When I was driving 30 miles to work one way, I was getting better than 20 in my 2.5, that was on 2 lane roads with no more than 55 MPH on 235's, 3:55 gear on an AX4.
project88mj Posted March 11, 2009 Posted March 11, 2009 i get about 16 last time i checked 4.0 aw-4 and 30" tires with 3.55 gears
Spokes Posted March 11, 2009 Author Posted March 11, 2009 20 highway, 16-18 city with 4.0/AW-4 on 33s how are u doing that?????!!!!! ive got 31s!!!! come on! i don't even mash the pedal
89eliminator Posted March 11, 2009 Posted March 11, 2009 i dunno. what gears do you have. I'm running 4.10s with the 33s. and 20 highway wasnt a one time thing. i get consistent 20s every road trip.
Spokes Posted March 11, 2009 Author Posted March 11, 2009 i running stock gears... my next set of tires might be 32s so if i get them i might regear it.
Jerry Posted March 11, 2009 Posted March 11, 2009 20mpg average with 2.8L daily driving, around 17mpg hauling the camper :thumbsup: Who says the 2.8L is rubbish ;)
Geonovast Posted March 11, 2009 Posted March 11, 2009 23 before it started acting up. 2.5 MPFI AX-5 3.55 on 205/75R15s Haven't been able to check the 4.0 yet since it doesn't have a non-leaking tank in it. I'd be it doesn't do too well, since I have a tendency to hammer on it.
BLHTAZ Posted March 11, 2009 Posted March 11, 2009 15-16 in town...don't do any highway driving with it. 4.0L, 4x4, 5 spd, 3.07 gears, 31" Swamper TrXus MT's
pantera1973 Posted March 11, 2009 Posted March 11, 2009 17mpg city, 20 mpg highway. 1988 MJ, 179,000 miles, 4.0, AW4, 2wd, 3.55 rear, 235-75-15 tires. Pretty close to what the EPA said it got: http://www.fueleconomy.gov/feg/compx2008f.jsp?year=1988&make=Jeep&model=Comanche%202WD&hiddenField=Findacar :chillin:
mjeff87 Posted March 11, 2009 Posted March 11, 2009 :shake: it's more like gallons per mile, not miles per gallon 4.0/AX15/35's and 4.56's.....+6" (or so) of lift Jeff
Car RamRod Posted March 11, 2009 Posted March 11, 2009 24 on the highway is I keep her at 60, but I can't do that for long so I dip down into the low 20s. I average about 19-20 city/highway.
Comanche County Posted March 11, 2009 Posted March 11, 2009 20-24 before the lift with stock rims and 30x9.5x15s with 3.07 gears 16-17 after the lift with 15"x8" steel wheels, somewhere about 6-7" inches of lift, 3.73s and 33" Mickey Ts. (no $$$ for lower gears right now), I'm going to throw my 31's on to see if it will be better. It's a 89' with 4.0 and AX-15.
pantera1973 Posted March 11, 2009 Posted March 11, 2009 I'm assuming folks posting their mileage whom are running larger than stock tires and/or gears have swapped their speedometer gears or otherwise compensated in some way? :???: Otherwise your true "miles per gallon" is WAY off.
BLHTAZ Posted March 11, 2009 Posted March 11, 2009 :shake: it's more like gallons per mile, not miles per gallon 4.0/AX15/35's and 4.56's.....+6" (or so) of lift Jeff Yours should not be terrible Jeff. Our YJ has basically the same set-up and gets 17 around town.
mjeff87 Posted March 11, 2009 Posted March 11, 2009 yeah, but I'm running a shorty cat and a glasspack, and LOVE to hear the exhaust music and don't mind getting into the skinny pedal to scare the neighbors :evil: :evil: Plus I'm carrying about 400 lbs worth of tools/chains/spare parts in my toolbox, plus an engine or two at any given time ;) With my screwed up fuel gauge notwithstanding, I'd say I'm getting about 10-12 mpg. Far cry from when I first got it in stock trim and it was my DD....I was pulling down low 20's. Ahhhhh, those were the days.... Jeff
ComancheKid45 Posted March 12, 2009 Posted March 12, 2009 I'm usually between 9-13....this is mainly just driving around town 30x9.50x15 on Crager D Windows and my Speedo is NOT corrected....so mine may be alittle better than I'm reading
mvusse Posted March 12, 2009 Posted March 12, 2009 Actual mileage corrected for tire size is 24mpg going 60-65, 19 going 70-75, 15 around town, 17 mixed driving. That is an 87 (Renix) 4.0, AW4, 3.55 gears, 4wd, P235/75R15 extra load range at 41psi. Mileage has stayed the same after 4.5" lift.
WyoCherokee Posted March 12, 2009 Posted March 12, 2009 between 22-26 with 88 2.5, ax-4, 3.55, 215/75/15's 2wd bone stock at 65-70. twice got 28 drafting a semi at 70 from Winnemucca, nv to Reno,nv and from Evanston, wy to Laramie, Wy with a 30 mph tail wind about 16-18 city
mvusse Posted March 12, 2009 Posted March 12, 2009 My 94 XJ (HO 4.0) with AX15 and 3.07 gears get's 17 around town babying it, just under 20 going 60-65, just over 20 going 70-75. So my Rexix 4.0 gets better mileage (24mpg at 60-65), but the HO gets better at high speeds.
HOrnbrod Posted March 12, 2009 Posted March 12, 2009 Good thread. I'm getting a consistent 15-16 MPG around town; 19-20 MPG highway cruising 65-75 MPH. Speedo corrected for 4.11 gears and 31" tires. Not bad for the stroker. The new intake manifold helped. :cheers:
