I have a 2011 4cyl.,5spd.,2WD.I went on a trip to where Im from for Thanksgiving.Before heading back I filled up.I had used 7.4 gallons to drive 198 miles.So that's 27 mpg.Did 75-85 for 90 minutes then climbed mountain after mountain.The truck now has 650 miles total.So I think after it's broken in if I hypermil a little I can get 30mpg.

I put a Scan Gauge in the truck and confirmed that, on average, at 65 MPH my '08 Ranger 4 X 4 with a 4.0L gets 23.7MPG. Around town it's considerably lower. That's not too bad for a truck.

(By the way, my old '78 F150 4 X 2 with a 4.9L '6' used to get about 22 MPG on the highway with overdrive.)

15 or 16 mpg in my '01 4.0 supercab 4x4 4.10 LS

If I was really worried about it, i would have bought a Volt or Prius

Not worried about it - just cheap and have been laid off for nearly 3 years.

You can try a bed cover which may help a little. Go to sythetic fluids all around, it may help some but even if the mpg's stay the same, at least you will have better drivetrain protection.

I would suggest getting a Tonneua cover. I got one about 2 months ago and i average a little over 1 MPG better with it on. you could also get a programmer, try to stay under 2500 RPM, or even get underdrive pulleys. All of those will help your gas mileage for sure. you also could try removing your air intake silencer, it won't do much if it anything at all but its free, has a chance of helping a tiny bit and adds some cool sound when you step on the gas.

I did 200 miles of driving yesterday and really paid attention to what the scan gauge was telling me. About 15 of the 200 were around town. I noticed a few things: when the speedometer in the dash reads '65' mph the scan gauge reads '63' mph. The truck is 4wd and is an extended cab. I've got stock-sized Michelins on the truck filled to the pressure noted on the door post. It has no bed cover and, other than myself (220LBS), I was carrying another 100 LBS of stuff behind the seat. (I don't know what the gear ratio of the read end is.) I used the cruise control. The only modification is a K & N filter.

The avg. mpg as shown on the Scan Gauge was 29.7 mpg. I then refilled the tank and calculated the mileage - the same right to the decimal point.

When I drive like normal on the highway '75' mph +-, the mileage drops to the lower 20's. Around town it's dismal.

A week or so ago we drove my wife's Mazda CX-7 (turbo-charged 2,3L AWD) for the day in mostly highway driving. The car couldn't crack 20 MPG. I have to say, though, that I held it to 75 to 80 MPH all day. (It's hard not to when you've got turbo boost to play with!)

Hi guys just signed up on this site. Got my 2011 4.0L 5 spd manual three weeks ago, 21.5 mpg so far with better than 60% highway commute. Not to bad I think. K&N filter on the list for first mod.

There is a million of these threads. It's getting really annoying. People you drive a truck. You aren't ever going to get great gas mileage. If you don't like it then get a car. Not trying to be a a** or anything. Just my opinion.

Yeah I would agree that the K&N doesn't offer tremendous mpg increase but it does help HP a little. I run K&N in both of my bikes and I put one in my wife's Infinity too. She noticed better performance right away. Ah we'll see. That reminds me better get the cleaning kit out a clean them all.... lol.
As far a tonneau.... not sure yet. Not sure about the look and function as I plan to throw mulch and dirt in the bed soon.

thanks

In the end IT A TRUCK.

I run my tires at 35 psi and use ethanol free fuel. I routinely get 17 mpg around town, and out on the highway running 70 mph I'll get 20 mpg.

The only time I've topped 20 is in January 2010, when I made a trip of some ... 400 miles on secondary highways and had the cruise set on 60 mph. On that trip I got 22 mpg, and that was pulling a trailer with a motorcycle on it.

Re, the repetitive posting of old topics: I'm new here but have been hanging out and posting on motorcycle boards since 2001. Over on AdvRider they have merged "threadfests" on certain topics. One of them has had just over 9,000,000 replies!!! I keep waiting for that sucker to crash the database.

To wit: the DR650 thread: http://www.advrider.com/forums/showthread.php?t=135295

The procedure puts a lot of work on a volunteer with mod privileges to keep up with it, but it does keep the postings cleaned up. The upside is that if one can overlook the random nature of the merged threads, he can glean scads of good information on the topic.

I run my tires up to 45psi now. Using fuel with up to 10% ethanol in the middle of winter I'm still getting 18mpg. In the summer it will vary since I pull a trailer, but anywhere from 18-21mpg

18mpg in the winter....thats insane. We have had the warmest winter in years up here, and my last tank was 11.2mpg. I feel like my truck is near death. I'm going to do another tuneup in the spring, but i still didnt expect the mileage to drop so much.

i been getting 19mpg lately. probably the best ive seen in my truck. i dont look to see better but i use it as a tool to tell me how my car is running. obv if its high then its running good. if i saw 11, something is wrong.
do some plugs, sea foam (however im undecided with it), filter, fuel filter, all that good stuff.

If I tug along at 40 mph and the RPM's at 1450 my scan gauge reads upper 28 to 32 mpg. But who drives 40 MPH? It was in a snow storm in 4 wheel drive though.

After getting my scan guage I have found ways to get better MPG from the 2003 4x4 4.0 AT FX4 Ranger. Anticipating red lights by letting up on the gas as soon as you see yellow. Keeping the RPM's down, there is a big difference driving 55 instead of 60 or 65, about 3-4 mpg. No warm ups in the cold mornings. No heavy stuff in your truck. (I've heard some people going to the extreme of removing the spare tire.)

I am planning on getting a tuner for mine after reading This Entire Tuning Thread. If you search dyno tuners in your area the techs there could probably set you up real good as they probably do alot of fleet trucks for delivery people. One big thing is setting the shift points.

I got my scangauge used on ebay nope, scratch that, Craigslist for $125 shipped. They are selling for about that on eBay but you should watch what version it is.

Drive like a grandma for a few fills to see wht you get. Make a change and drive a few more fills to see if it improved.

wintertime i get about 16 MPG city, 20 highway. summertime that will go up to about.... 18-19 city, highway is around 24-25.


fuel savers are gears, E-fan, K&N, Tuner, Tonneau cover. its not bad for a truck in winter, on 33's and a 4" lift.

A lot of people mention the tire pressure. I always look at mine and say "Yep, they got air." In anticipation of getting better gas mileage, today I actually checked them. The first time since fall when I was brining home the camper in my avitar picture. I thought I had put 60 psi in them at a cheep gas station air pump. I checked them today and they all had different amounts ranging from 20 to 32 psi. I set them all at 60 psi and felt an immediate difference in the roll down the road. the sluggish feeling was gone. I run Dunlop LT tires with an "E" rating. The sidwall says 80 psi max with a full ~2200 lb load.

All the little things add up.
