so far light foot helps the best

 

I get about 22.5mpg driving about 60mph all the way down US12 then about 75mph on the freeways. Would slowing down help me out at all? I figured between 22-23 would be the best I could do...

 

Yes... it's not true for all cars mind you. But the wind resistance on these rangers does hurt milage. Especially if you have lower gear ratios. Like 3.55s or lower.

The higher the ratio the less it'll effect your milage.

In my 05 FX4 Level2 I was getting about 17mpg with no mods and a mix of city and highway.....I could get close to 20 on the expressway when I was heading up north

 

Just filled up last night and I went 379 miles on 17.3 gallons. That equals out to 21.9 mpg 90% city 10% highway.....

 

Rich,

My mileage went up with taller tires bringing my 3.55 lower yet, so how does that work out?

 

Keep in mind I said that wind resistance will have a greater effect. Yet at the same time a taller gear (or effective gear ratio) can / might / will improve mileage.

It all comes down to the torque curve and load on the engine. For example.. I took the lightning to Tenn in 05. It's got so much torque that at light loads the fuel consumption was pretty much the same no matter what.

Cruising 65mph through IN netted me 17mpg. And somewhat hot footing it through the hills in Tenn netted me 17mpg. Actully on that whole trip the only time my milage dipped was when I was rippin up pavement around deals gap. Then on the way home through OH I went through the storm of the century for about 100miles. Huge rain and wind.. 17mpg there too.

^^^^I see.... Thanks for the clarification.

 

thats good mileage on that 4.0? my 07 fx4 off road see's maybe just over 300 miles to a tank with mix driving. also i have only 2000 miles on the truck. maybe if i get some more miles on it ill see better mileage. but its not a problem. i have a 4 banger mazda pickup for a daily driver.

 

ok then my truck is ****ed up i figured it out on my 19.5 gallon tank i got 213 miles that 11 to the gallon what the hell it wrong with my truck could replacing the plugs help if so what should i get

 

If your getting that bad of mileage then it's either your driving technique, a bad 02 / MAF, or you forgot that the 25ft boat is still hitch on the back. Or somethin..:-D

I don't think plugs are your problem. More than likely it's a combination of driving technique and parts that are wore out.

Just to grind a little salt in your wound there.. This morning on the way to work my guage has fallen below 1/2 and the odometer is showing 250 miles.

grr so what all is done to ur truck

 

K&N conical kit, Underdrive crank, e-fan, bama tuner, Magnaflow aftercat, over inflated tires (40F 38R), and a easy driving technique.. I brake as little and as lightly as is possible / reasonable.

Filled up Monday... 21mpg and the driving was 80% city.

Rich

 

I have the sohc, running 33" DCs, 4" suspension lift and dual magnaflows ... I'm lucky to get 14 mpg and I drive easy.

 

seems like driving style makes the biggest difference... always thought the sohc would have better fuel mileage than the ohv but have seen on this thread the opposite can be true...if my opinion best way to get best fuel mileage affordably to to make sure truck is probably tunedrmove unnecessary items from truck and adjust driving style as required... have already toned down my driving style since leaving honda ( i'd consider myself an aggressive driver)can't justify the price of some of these mods especially if minimal gains very hard to get great mileage especially on a 4x4 ( higher,heavier,etc)

 

I have a 2003 entended cab FX4 5 speed. I normally get 20 mpg around town one time i manged to get 22 mpg milking it. If i run it through the gears alot 17 mpg. I have found that shifting every gear at 2500 rpms helps and remember lower rpm's on hills doesn't mean better gas mileage.

 

that should be a no-brainer. I know that if I drive at 90 vs 80 it cost me 2mpg. I pull a littel under 20 at 80

 

i have a 01 edge automatic with 50XXXmiles and i get like 160-170 max a full tank. I love the truck but cant aford to go to the gas station ever 2-3 days. I dont have a led foot. and most of my driving is city. I just changed the spark plugs and change my oil like ever 4XXX. I also just got a flowmaster cat back exhaust. I rarly go 15 over the speed limit. I do like 7 or so over

Anyone have any ideas why my truck likes the gas station so much?

 

I've got a 2001 Edge v6, standard tranny, 114k miles. Last time I checked I was getting almost 22mpg city/hwy, and I think my last fillup lasted for 350 miles (i'll have to go check my reciepts to see the exact amount). I will be driving from Dallas to Port Aransas in 2 days and staying a week there so I will finally find out my HWY mileage (7+hour drive down I35)

 

i got almost 1.5 mpg better since i added my soft tonneau a few weeks ago. even driving light footed my best is still about 18.2 mpg. i figured if i take off my step bars and rear mud flaps, i might be able to best 19.

 

i liek driving slower my exhaust sounds better accelerating slow =)

 

Some of ya'll have to have something wrong with ya'lls trucks. Even with my double lifted 3.0 with 33's and 4.10's auto 5spd tran was getting 18mpg flying around town. Aerodynamics DOES have alot to do with mileage though. You guys with the body lifts are worse off because you got your front suspension hanging down an extra 3". The body lift alone cost me 1mpg so keep that in mind, if you want to make your truck more aedynamic go buy a skid plate. Also, make sure you guys are re-calibrating for different size tires. I put up a fairly easy formula up here before but I'm not sure anyone saw it.

You take:

current tire size
stock tire size

and multiply it by your uncalibrated mileage to get your actual mileage +/- 1/2mpg

 

Some ideas..

A dragging brake?
Driving style?
Bad 02's?
EGR not working?


Rich

 

^^^ Yeah, something is wrong with that truck for sure. Clogged air filter or fuel filter? What about tire size?

 

even though i have a tonneau myself stating to doubt its usefulfulness....my friend told me that mythbusters had an episode proving that tonneaus and having the tailgate down in fact burns more gas due to way the airflow is changed
