alright i got a 2001 ranger 4.0l sohc that is somewhat lowered and is 4wd..i get 13mpg..its got new plugs and wires, fuel filter, kand n drop in filter, just installed e-fan and my chevy 5.7 gets 17mpg and thats not being easy on the pedal...what is the deal with this truck?

 

Are you calculating correctly for the tire/wheel combo that you have?

 

my tires are 275/55/20 which is Overall Height: 29.64"
factory i believe is 31"

 

dude i get better then that with 37s

 

^^^ I get better than that with a thirsty Chrysler V8.

Maybe a clogged cat? Did you replace the plugs with motorcraft ones? dirty MAF and filter? o2 sensors?

 

i put autolite double plats....no codes are being thrown out..maf was cleaned last week..filter is a month old and is very clean

 

i just filled up my 08 fx4 and this tank i got 13.6 mpg's!

 

highway mileage i get 20 mpg.. and thats with 33s, steel wheels, and an automatic

 

hole in the gas tank?? lol

I am stumped then, what about the condition of your engine, trans, xfer case, and diff. fluids?

 

yall just got heavy foots

 

Engine has 90k..been maintained reguatly..both differentials have been drained and refilled same with tranny and t-case

 

Ok, i am done then....lol Even in below zero weather with a lot of idling my jeep gets 14-15.

 

i get 13 all the time im convinced rangers suck for gas milage

 

yea ill typically get between 13-15 depending on how im driving

 

Did you gap your plugs this time...?

 

i wish i got 13

 

i get 14 combined, and 16 all highway. 33's, auto, steelies, and 4.10's. It's got 92K and burns oil faster then gas too. But even still i got 13mpg when i was only driving 2 mi's to work everyday in complete stop and go when it was stock.
What about a coil pack? How about wheel bearings and alignment?

 

x2! Was gonna ask properly gapped plugs????? Does Georgia run 10-15% ethonal in its fuel for the winter?? that 10% ethonal in oregon brings my mpg down to about the 14 range.

 

not mine I avg 25 in winter and 28 in summer city driving

but then again its a 2.3

 

^^Add two cylinders, double the power, add a front diff, add 31s or 32s....and you'll see our mileage.

 

yea they just started that a few months ago

 

That would be it I bet, because you should get 15-17 city driving in the summer (non ethanol gas).

 

summer fuel has ethanol too, they just have something else mixed in that makes it worse. my mpg is 13-14 with the cold weather. short trips are not helping your truck out any. and the more you let it idle that does not help either.

 

I just went from the 235's to 31's and my mileage went from 19 to 18 city driving. I didn't even get that low when I had my 3.0 with 33's. I do have to say that the cold weather will affect the mpg somewhat. Try running some fuel injector cleaner through it.

 

Not all summer gas does. Michigan law states that you must advertise if you use ethanol in your fuel. Buying Bp, Mobil and Sunoco will get you gas that is ethanol free (at least in the summer months) Speedway even has stickers on there pumps that state, 10% ethanol...
