We have V8s guys, don't go expecting much more

 

Did the check your muffler belt? Maybe its slipping.

Sorry..Fuel Maximizer?? wtf...i think they were joking

 

Its normal but it does vary depending on your environment.
I live where there are a lot of hills and traffic. Im lucky if I see 250 miles mer tank.

 

i get about 260-265 miles per tank

 

My roommate had a popular science magazine with a bunch of "fuel maximizers" such as the tornado and the magnet thing and a few others including some off brand programmer (I had never heard of it, and the mag is gone) and i think some of the drop in air filters (K&N wasn't tested, not sure who all was), and the dramatic conclusion was...... drum roll please..... not a single product tested improved gas milage or horsepower/torque. As a matter of fact every product tested had a negative effect on gas milage and power. So I'd find what they installed, remove it, and sell it on ebay for some chump to buy, and use the money to purchase some mods that have been proven to better your performance.

 

2005 SCrew, 4x4, 5.4L, 3.73s, 11-12mpg in the city. I once saw 17mpg on the highway with no A/C.

 

I just completed a 768 mile trip from Houston to Columbus Ga. The first tank got me 463 miles before the "Low Fuel" message. Still sitting on 1/4 tank of my second fillup but I estimate that this will get me around 425 or so with mixed city driving. This is with cruise control set for 80mph through Louisiana, Mississippi, and Alabama.

If I was only getting 250 miles on a 27gallon tank I would be trading this truck in. That's only ~9.25mpg, I am easily getting double that.

My setup:
2004 SCab
4x2
5.4L
3.55 nonLS gears
235/70R17 Hankock
last PCM reflash: March 2005

 

you also have a 4x2, 3.55 gears, smaller lighter tires, less air gets under you, and your truck is only a ext. cab.

I finaly broke 10mpg today!!

 

I usually average somewhere between 11 - 13 mpg, depending on how heavy my foot gets around town. On the highway on extended trips, I usually average 15.5 mpg, setting cruise to about 80. I have a screw, 4x4, with 3.73s for reference.

I have noticed however that the MPG on these things tends to vary quite a bit, depending on driving conditions / styles though.

 

ya i'm getting around 12mpg in town but thats because I drove probably 90% in town half of my town where I live is pretty big hills and going up and down on those is hard on the gas but otherwise if I lived in a flat area I think it would be better

 

x2 Mine is a little better after 13k miles, but it did not go up much.

 

why not? Ihave an 04 while my buddy has an 04 Hemi Ram. Both of us see 10mph compared to ur previous trucks (my F150, his Silverado) that would see 16-20mpg.


I know its a V8, but 50% increases in fuel usage are a joke.

 

I wrote this in the past, but my average is over 20mpg for the whole 15K miles I put on my truck. I've gotten as high as 22.5mpg on a tank of gas (90% highway miles). I put that in a classified add I'm running to sell my truck, I hope it doesn't look like I'm being dishonest with all the low MPG reports here. I know 22.5 seems unrealistically high, but I drive very conservatively and stick to the speed limits. My truck has the 4.6 V8 with Auto, and is 2wd with standard 3:55 gears and stock 235 tires.

I know most already know this, but the way to increase fuel economy is to take off slow and gently and get off the throttle way before a red light. Helps to keep the tires at max recommended pressures (38psi recommended for mine). Driving in hilly country will takes its toll on fuel economy a bit.

Everyone already knows that. Also you are reporting the highway miles. Most of us care about city driving mpg. Also as you said you're driving on those tiny 235 tires while most of us on this forum are 33s and up. IMO I could really care less about it because I only drive 12miles to work. We have v8 Ford's a males truck. Don't complain we choose this thing.
