Hey Guys, I Need A Little Help With This One. When I First Bought My Truck I Was Getting Around 17- 18 Miles A Gallon, Now Im Lucky To Get 12. Is There Anything I Can Do To Get Better Gas Mileage. I Change My Air Filter Regularly And My Fuel Filter. Any Help On This One? The Truck Has Around 100,000 Miles On It. It's Not A 4x4 Just A Plain Jane 2000 Ranger 4 Cylinder

 

Have you changed out spark plugs/wires? O2 sensors (Last thing I would check...do the others first)? PCV valve? Tires at correct psi? BTW, if you could make a sig for us, it would help.

FYI: @ 100,000 miles, change out the rear axle lube also.

 

HOLY S!!! 12mpg in a 2.5??? My little brother's '01 Ranger w/ a 2.5 gets 19-22 regularly, granted it only has 20K on it.

Start to look for a tune up. Get it done, and those numbers will come back up.

 

i 99% know exactly what it is because my brother had the same problem in his 98 2.5... he should be home in like a half hour so ill ask him what it was

 

100K, check o2. they usually take a **** around 100K. add that into a regular tune up.

 

Run a couple of bottles of Textron Injector & System Cleaner through it. Full bottle, half tank; full bottle full tank. My 3.0 v6 went from 17/24 to 20/26.

 

Brakes dragging?
Soft tires?
Old spark plugs and wires?
Fuel leaks?
Vacuum leaks?
Defective sensors feeding bad info to the computer?

I would say it's Tune-up time! Get it done right, don't throw parts at it. Get it into a dealer of other shop that has a computer and can do all the fancy diagnostic stuff. It will cost you far less in the long run than throwing parts at it.

My 2004 4x2 4.0L SOHC V6 was getting 19+mpg at 130,000 miles with all original spark plugs and wires and sensors until a 10-point buck leapt out in front of it at 80 MPH. It now works as a stripper.
