I just bought one last week and found that too, but on my trip to Montana from California I too was getting only 200 miles to the tank, but on my last gas stop coming home I got over 300 miles to the tank, don't know why it got better, but it sure made for a good feeling not to stop for gas for the six-ed time.

I would have to agree with you all. The gas mileage on my 2001 Ford Ranger is not up to my satisfacation. I am searching to see if there are better ways out there to make my gas mileage improve. I heard something about a computer mechanism that should help out. However I cannot find one for the Ranger.

My brother has a 4.0l Ranger. He gets 18-20 mpg. Take your foot out of the floorboard.

MY 2001 4x4 Ranger only gets about 14 miles per gal in town 16 on the hi-way.

What do you expect? (90mph) Lift your right foot up. If you have a 4.0 engine you should get around 16-20 mpg. Don't expect to get the mileage of a civic..it's a truck.

I was getting 19-20...then put in a K&N filter... now I'm at 16.

Check your mass air flow sensor. Its located between the filter and throttle body. Many times the filters are over oiled. All of the oil that was on your filter is now on your sensor. This gives the computer a "bad" read and tells the computer to send more fuel.Don't use carb cleaner, it will damage the sensor. Give it a try and you might get improved gas mileage.

2001 Ranger XLT 4DR 2WD. 3.0 engine. Gas mileage is HORRIBLE! I once read a trick for a 91 Mercury Capri was to drill a lot of holes in the air filter housing. I'm wondering if that might help some. I just filled mine up on July 6th, 2007, and I got right at 14.6 MPG. There has GOT to be SOME way to improve the economy on this truck! IF anyone comes up with ANYTHING, email me at what_about_tfi@yahoo.com and put "RANGER" in the subject heading. I'm just a good ole Southern boy that HAS to have a truck to survive. However, I don't have stock in any oil company! Other than the gas mileage, I really have no complaints about the truck. It's solid, reliable, and have never had any problems with it. YOU GUYS TAKE CARE!

I recently bought an 01' ranger single cab 3.0L 2WD work edition. When I bought it, it had about 140,000 miles and it runs great. It's an all around great truck. But I'm also having to deal with the bad fuel economy, and going to and from school every morning isn't helping. Most of the time I'm late and I have to rush. And 90mph just doesn't cut it on the interstate. I NEED advice on how to tweak the governor. PLEASE. Plus my check engine light's been on for about two weeks now. I'm pretty sure it's just a bad reading with the sensor.

I've never been real impressed with my Rangers fuel mileage, but I guess I should be counting my blessings. I bought my 2001 4.0L Ranger new. It has about 60K on it now. Just yesterday, I returned from a trip and got 22.5 mpg on one fill up and 21.5 on the second. This was at Interstate speeds of 75 mph. I have the manual trans with overdrive.

Wow that gas mileage is pretty weak, and the topping out at 90mph is pretty weak too. I have a 2001 2.3L 2wd and I've been up to 100 and could probably go faster. so I don't know whats up with your guys trucks, and I get a sweet 27mpg highway hahaha.

So I guess bigger isn't all ways better ;p.

I have a 2001 four door, 4.0 liter Ranger. I installed the K&N filter and a Jet performance chip. The truck ran fine for about four months. Now I get the check engine light with the codes reading #1 and #2 banks running lean. I will be pulling the mass airflow sensor to see if it needs to be cleaned. Today the engine actually quit without warning (and I didn't get any lights either - weird). After turning the ignition off and letting it sit for 10 seconds, it started and the check engine light went out. After about 10 miles, the check engine light came back on (I haven't pulled the codes yet). All in all, this has been a good truck, but the electronics have me concerned. By the way, I have hit the governor limits as well. I average 18 mpg city (automatic transmission) and 20-24 highway, depending on the length of trip and terrain.

I have a 2001 Ranger 3.0 4x4 that I bought used with 45k on it. I was getting about eight miles to the gallon, which was absolutely outrageous considering I was expecting 18-22 (according to Ford..) so I decided to check the air filter; 8 acorns, a very large squirrel nest, and a fram air filter later, I'm getting about fifteen. Not thrilled, but it beats 8!! I had one of those vortec things in the intake, but I took it out whilst trying to cure my 8 m.p.g. maybe I'll put it back in..

I recently bought a 2001 Ranger XLT, 4 door, 3.0, Flex Fuel, 98k miles. It has K&N Filter and 235/75R15 (oversize tires). I had the computer recalibrated for the tire size at a Ford Dealership to make the Speedo/Odo read correctly. I'm get BAAAAD mileage too. I didn't at first. At first I was getting 17 city (Los Angeles) and 27 highway. I attributed the poor city/good highway mileage to the tires, which result in lower RPMs at highway speeds. Anyway, I have a rapid clicking noise coming from the left side of truck when accelerating onto the freeway. It starts at about 2500 RPM and stops at 4000 RPM or if I let up on the gas. So, thinking it was engine ping, I tried an octane booster. BAD IDEA! The ping didn't go away and my mileage DROPPED to 12-14 city and 17-19 highway! And it acts like I'm dragging a ship anchor behind me after driving for several hours. Whoa! $100 to Ford to troubleshoot and NO TROUBLE FOUND. Hmmm... Well, I had some old O2 sensors (from a '93 Taurus) and put them in. My fuel economy has gone up some. Looks like the Octane Booster dealt a death blow to my O2 sensors and possibly the CAT. So, I'm going to put in new O2 sensors and see what that does. I've had no codes at all this entire time.

Oh, by the way. The 90 MPH limit SUCKS! But here's one for you. If you hit the 90 MPH limit or REV Limit, it will set a code in the computer. For my $100, Ford Service did tell me that the limits had been hit/set in the computer. What can I say, I had to try it out to see for myself. Yep, 91 MPH and the engine starts cutting out.

I'm considering removing the K&N and going back to the stock filter. I don't see an advantage to having it.

The tuned exhaust sure sounds SWEEEET though.
