On my trip to Virginia and back, I got amazingly good gas mileage.

I filled up five times and the calculated MPG of each tank was 20,21, 23, and 24

I was so shocked that driving a long distance even with a load in the bed gave me great gas mileage... I never thought Id be gettin around 20 mpg with my trcu so the 23 and 24 were shocking.

I guess have a CAI in my old airbox with the silencer removed help me here. The silencer removal was done last week and my i think its workin on gettin the cold air in there.

I also only ran 87 gas which I have never done. I usually run 89 all the time, or sometimes I do 88 at one of the stations in town.

 

thats about the same as what i get, just gotta drive sane keep up with the maintenance and the 3.0 can do alright

 

My 4.0L loaded down with a bed full of fire wood............26mpg!

 

I like hauling large rocks for landscaping purposes, and hauling 300 pounds of stone gave me a 3-4 MPG increase....gotta love it :)

 

Hrmm, this is interesting information, I like weight in my bed as it makes the ride better. Do you guys think you got better MPG because you were cruising at a slower speed with your loads?

 

Well, I have been getting around 18-19mpg here lately and I have over 160miles on 1/2 tank right now, and I usually get better mileage on the bottom end of the tank, so we'll see...

My guess is the weather.

 

When i go up north I probably have 2-300 punds worth of crap in the bed (under a tonneau cover) plus the GF, the dog and a row boat (loaded and ready to roll 650 pounds) and I get 24 with my 4.oh......

Of course I have a 3.55 with 2WD, a 5 spd. and a few mods......

 

lol geeze graygooseranger ya callin the g/f fat? lol j/k


mike

 

^ lol

 

Maybe the weight in the rear helps grip better, requiring less torque to go? I dunno

 

how do you remove the silencer?? what does it do??

 

weird...but it does seem that you get better mileage when carrying a heavy lod.

 

If anything, it would require more torque.

 

i got better mpg towing my mustang when i brought it home from KY.

 

Hmm this might be good to know. i've got 400 lbs of axles in the bed and I'll be towing a 2200 lb zuki. Hope I can get that good of mileage too!

 

could it have to do with momentum?

ie. if you're rolling on highway and you coast more because you're maintaining speed, the injectors will shut off for a longer period of time

 

Yeah, well my truck was getting.....14, 11, 13 mpg and last tank i got... 15.2!! wooo! not ha. Monday I'm gonna replace plugs,wires, fuelfilter, air filter, change oil, get the radiator flushed, change tranny fluid. Maybe that will help.

 

well, i drove a tanks worth of miles and got 2 mgp less when i was hauling a 600-lb small block. not sure how you explain your results.

 

My wife and I bought a load of harwood floors in Georgia a few years ago. I hauled it all back down to Florida in my previous truck, the 04 F150 FX4 with the 5.4 V8. I never had gotten even close to 20 for highway miles, but figured the mileage on that trip at 21.9. I thought about keeping it in the bed permanently!
