Have a new 2008 4 liter 4x4 Ranger with 1200 miles on engine,will my gas
miledge get any better or will it stay the same never had a new vehicle befor,
maybe somebody else with a new Ranger would know .Thanks. i know the
4 liter is not great on gas,but i really like this truck.

 

What are you getting now?

 

You only have 1200 miles on it. The engine just starts to "warm" up at like 10,000. Then you'll be getting "normal" mileage.

 

Bruno, I bought my 06 FX4 new a year and a half ago. Up around 2000 to 2500 miles it seemed to get a little better. Not much but a little.

If your gonna keep the truck for 100k or more miles. I'd suggest buying two things for milage. A X-cal 2 tuner. And a crank underdrive pulley. Both of those will indeed give you results.

btw, I average 19 winter and 20-21 summer in 50/50 driving.

I need to try that crank pulley, its the only thing i have not done! LOL

 

I've put them on three different engines and have been very happy each time.
5.0L, 4.6L, and now this 4.0L

btw, IMO the 4.0L crank is very small. I'd not put underdrives on any of the other pullies in conjunction with it.

The pulleys for the water pump and alternator? I thought those were to speed it back up?

 

my 07 fx4 off road has 5400 miles now. im getting better mileage then when it was new. im thinking 15 to 17 city and 20 highway if im lucky. stock truck. i like the power of the 4.0 sohc motor. i use my little mazda 4 banger for daily driver. ranger only comes out on weekends or drive to the shore. auto trans.

 

My 2008 4x4 on 33" tires is averaging 14 now which is low because i haven't calibrated it for the larger tires. It was 19 mpg stock. i got no improvement when i did the intake and muffler. I just hit 5k miles. X-cal tuner is next, thats gonna be the biggest improvement I think.

 

thanks for the info,thats is exactly what i am going to do X CAL 2 Tuner and
crank underdrive pulley ,you guys are great.

 

Just returned from a trip with my 4.0 L fx4, and on the way up I drove like an old man, (got just under 26 mpg) on the way back I drove more aggresive and ran around 20 mpg

 

Really? I did'nt know that. I was assuming that they only slowed them.
If that's the case, then for those two components:
Larger = slower
Small = faster

 

I'm sorry that is just the Alternator Pulley

The water pump is a underdrive, which would slow it down even more.

in my 2000 3.0 liter 5 speed ranger, its a manual

i drive ALL backroads where i live, stop signs everywhere too and on a little more than a hlaf of tank of gas i've gotten 110 miles on my most recent fill up

how big of tank do i have? anyone know? i just got this truck a few weeks ago

btw it has 61k miles

 

bruno, im a canuk too. you mean miles or kilometers? i've got an 08' specs in sig. i was getting 400-450kms a tank (95% city). now that i've got 6000, i'm getting about the same, just a little better. the one tank, i got 575kms. that was a trip to london and back and some city driving. i hope that helps.

 

I have an 08 4.0 with 5spd, and I consistently get 18-19 around town doing my daily driving. Have done any highway trips with it yet.

 

Your milage is lousy! I don't hit the 3/4 mark at less than 140mi but I hypermile where I live.
Now that I gave my truck a new set of plugs and wires I expect at least 25mpg. My 4x4 x-cab has 182.xxxmiles on it.
