I'm not complaining about the mileage at all nor do I care b/c I won't give up the truck at all. Your probably right with being so close and only getting about 16MPG, but its all good..Wasn't really expecting much from a 4.0, 4*4 like my old 3.0 2wd...Regardless, just like to see what I do for a tank and what I get is what I get..LOL

wydopnthrtl,

Could you list, in one post, what you have done to get 20's with your Ranger? Also, what is your truck: 4x4, stick, auto, gears, etc.?

I am looking at a 2007 4x4 Sport, auto, 4.10 gears, 23k miles. I don't know of any mods, the dealer is bringing me the truck tomorrow, but it does have a tonneau cover. I'd like to know the potential of this truck in terms of fuel economy. Most of my driving will be my 40 round trip to work: 2 lane highway, one turn, one stop. I drive according to what the vehicle seems to prefer. My PT Cruiser with a stick likes to be shifted between 3500 and 4000 rpms for best economy. I know that sounds high, but short shifts let the little 4 banger bog too much. I get 26-30 depending on winter or summer fuel doing the trip to work.

My 2002 Dodge CTD-HO, 6 speed, 3.55 gears likes to be shifted between 1800 and 2000 rpms. Best mileage has been just over 20, unloaded on the interstate at 65-70 mph. Average is about 18. Not bad for a 7000 pound (empty) truck.

What can I sqeeze out of the Ranger, and what do I need to do to squeeze it?

mileage

my 2001 ranger,4.0,auto is getting 16mpg 75% city/25% highway driving,50% of the time in 4x4 and also idling to warm up before leaving home or work for up to 1 hour at times. (I only live 1 mile from work, & we have had BELOW ZERO the past few weeks-at times during the night down to -30 degrees , with windchill, -60!) Never have a prob @ startup, block htr plugged in or not! Pray fer spring for me please!!!

Sorry, I missed this post.
First, I try not to look at just one tank / trip and take it as a "rule". An average of three tanks (or more) is a better measurement to report.

Saying that, It's been in the single digits here lately. And I've been averaging about 18 flat using shell 93 and a little acetone.
I drive 65miles a day and it's right at 50/50 stop and go traffic and 65-70mph freeway.

The specs & mods that will effect mileage:
2006 FX4 (4.0L, 4x4, auto tranny, 4.10s, open bed, 26k miles on vehicle)
Mobil 1 10w-30 oil
Stock tires over inflated by 3-4 psi
ASP underdrive pulley
Henson 93 octane performance tune (SCT X-cal 2)
Shell 93 octane gas
2.5oz of 100% acetone per 10 gallons of gas added at fillup (usually takes 4.5 to 5.25 oz when the low fuel light comes on)
K&N conical kit
Home made CAI w/ram air (fully seals filter against engine room heat)
Magnaflow after cat
Flex-a-lite e-fan
50lb tool box in bed
Easy attitude when driving

All my mods can be seen HERE

By constantly displaying instant MPG on my scanguage I've observed several key factors that will increase or reduce mileage.
1) Wind. A stiff wind (sideways or head) will take my 70mph instant mpg from 22-23 down to 15-16.
2) RPMs. I always thought that load was the real killer. Not so on this ranger. Keeping the rpms DOWN.. even at a heavy throttle will always return a better number.
3) Tire pressure. With my tires at 35psi vs 30psi there is a noticable and repeatable improvement.
4) Gas brand. I've run them all at three tank intervals. Shell 93 "V-Power" and sunoco 94 are the two that get the best. And they respond the best to acetone as well.
5) Road speed. Best "instant MPG" occurs at 45-50mph. (27-28mpg)
6) Oil change. For about two tanks of gas I get a little worse mileage right after a oil change.
7) Wife driving. I don't think she actually drains the tank.. but good grief I have no idea how she gets so bad of mileage!

Rich

Wow,

That's quite a list. I tried the Acetone in my wife's Accord when she had that, but didn't notice much difference. Then again, she was driving it
I can always beat her mileage for some reason. I think part of the problem is women are TOO light on the throttle. They just take forever to get up to highway speed. I don't do burnouts, but try to accelerate smoothly and quickly to speed. That seems to work better.

What mod would you say has been your most effective, both in terms of mileage increase and cost effectiveness?

i've finally thought to keep track of my gas milage. when i filled my tank the previous time, i also reset my trip meter. soo come this time i filled up (tonight) i took the milage (226.4) and divided it by the # of gallons it took to fill 'er up (17.2; yes i ran the sucker dry.. the 'check gauge' light even came on) and got a nice 13.2 mpg running 38's with 5:13's, never surpassing 70 on the highway.

just thought some of ya would like to know.

..i plan to continue to post for a few fill-ups at least to see how consistant i am (or am not)

It's been in the 4F to 8F temp range going to work, and in the teens on the way home this week. Filled up this morning and calculated a 17.0 The scan guage said 17.4 for the tank. Not that great IMO.. but it's better than a lot of you guys are reporting.

IMO the best mod for mileage was the SCT X-Cal tuner. It's $400 but.. it gave me a noticable increase. The crank underdrive pulley would be second on my list. It's $250 and gave a noticable increase in tip in power as well as mileage.

I put on about 16000 miles a year, so at the current price of fuel, if I could gain 2 miles per gallon with the tuner, it would pay for itself in less than a year. Hmmm, it's starting to look more interesting. Even one mpg would make it worth looking at.

Yup, that is what I did when I had my stick, shift sooner than normal, and put your foot into it more. keeping rpms lower netted me much better mileage. That is how I was able to consistently get 20-21 mpg in 90% stop and go driving...

thanks for posting that. i think my biggest down fall here is the temps and the horrible winds!

mine is about that hopefully it stays the same with 5.13s and 37s

I finally got to 300 miles on a tank..(70 highway, 30 city) .I usually fill up around 250-260 w/gas light on....Well yesterday it never came on at all i was just scared id be walking, so i filled her up...I shook the truck very hard for a little more juice....I put 15 gallons in and my trip read 307....so i got around 20-21 mpg....I try new driving techniques everyweek, i think i can do better too..........!!!

oh yeah...3.73s , 255/70/16 tires....overinflated tires 3 psi....I have been meauring every since i got this truck....the past two times i have gotten more MPG..it was 18, then 19, now 20-21

I actually think i need to change the fuel filter, PCV valve, maybe spark plugs and wires....i bet thatd help too....never tried the acetone, does it work well??? any harmful after effects?

I'm doing very good all things considered. It's been in the single digits and teens lately. Even so my last three tanks have all been over 300miles. The last tank I pushed to 340miles. (put a gallon in at home and then 19.0 the next morning on the way to work)

Last summer I had a few tanks go to 380-390 miles before the low fuel light came on.

i only have a 16.5 gallon tank...I filled up at a different station at my buds house when i got the 300 miles on the last tank....I filled up the other day at my reg place and the mileage is worse.....Usually i fill up at 1 place consistantly b/c my weekly rounds are consistant too so it just works out that way..

but gas flucuates so much around here...There are generally only 3 places i fill up at, all depends on the gas prices. and all local....anyways, good to see some people get well over 300 miles on a tank!!!!

200 is way low.

Assuming you don't drive like a maniac... I'd jack it up and see if you have a wheel that's not turning freely. Dragging brake or something...

damn thats pretty bad...Yeah what he said about the dragging brakes...Check the normal stuff, air filter, pcv valve, fuel filter..etc..
Check your tire press too, id over inflate them by 5psi

well, i get 20 to 25 mpg (i drive manual) and i have a 20 gallon tank. lets say i get 20 mpg always, im still gettin about 400 miles on a tank!

i drive a 2002 Ford Ranger XLT V6 4.0 SOHC FX4 with manual trans.

...400 mpg sounds a bit much, but im almost 100% positive that im right.
