I took my truck to fords about 3 months ago for a "tune up" offer, plugs,air fliter,oil and whatever else ect ect .So after this my mpg is fantastic,im getting 310 miles between fill ups( takes 15 gals when gauge is reading red) so ive 5 gallons left in the tank!! I drive highway roads to work and stay at 60mph,not bad for a 4.0L shoc with 112,000

 

twice as much as me!

 

Is your speedometer recalibrated properly? If you regeared adequetely, you shouldn't have noticed a huge hit in your MPG

 

wow i did u full tune up also and i still get 170 if i lucky with 4.0 ohc 4x4 w/ 95k miles u doing pritty well

 

Wow.... I thought I was bad. My truck does over 200 miles to a tank, but not much more.

 

so you are getting 20 MPG
sounds about average for 2WD 4.0

 

i get between 170-200 no more tho and i have top of the line plugs, wires, fuel filter, oil changes ever 3k, k&n, flowmaster and 245/75r16 tires W/ a led foot so i prob pay for that

 

better mpg's then me

 

Prior to installing the underdrive pulley I was getting 16-18 mpg highway.
Filled up the tank the other day and will see if the underdrive pulley adds any to the gas mileage.

OR 4x4

 

i was getting about 280 when the gas light comes now, now days its like 240-250. thats me driving on interstate 52 miles round trip to/from work.
i will be getting a tune up soon.

 

Awsome!!!! I gotta get a damn tune up!!!!!! I want this thing to roar!!!!!!!!! lol

 

Shortly after purchasing my Ranger in Jan '05; I gave the truck a tuneup with Motorcraft platinum sparkplugs and Taylor wires...

OR 4x4

 

hey charles. do you have an efan with those underdrive pullies?

 

I am really concerned for my fuel mileage. I am installing 60# injectors in my buildup!!!
