Damn. I expected at least 12 in town. That really sucks.

 

is it lifted? what tires? what gear ratio is in it? that sounds kinda low...

 

that does suck, my truck weighs in at over 7000 lbs. and is lifted and turns 35" tires and I get between 11.5 and 12 mpg in town mileage...

 

I get 9.5 - 10 all the time and it's probably my fault. I bought the Hemi for the power and I don't see a need to be lightfooted.

My truck is due for plugs & wires but I don't expect that to change the mileage -- just make more power!

 

Ease up off that pedal. The mod I made that made the most dramatic MPG gain was the E-fan. Give it a try...

 

im lifted a bit with heavy tires CAI and othe $hit and im gettin 13 in town e-fan is the next mod

 

im with hammer, about 11.5-12 in town...no long trips lately so i dont know how it is on the freeway. hell, mine used to be 10.7 before a few mods so im happy with 12 lol

 

Just a question:

Hows an electric fan help your gas mileage so much? What causes such a rise in MPG with the addition of this mod? Just didn't make a ton of sence to me.

 

you dont have to use then engines power to turn the fan anymore...its replaced by electric fans that use electric power instead of the engine power. think about how much u can feel it when your fan comes on...well, on mine anyways

 

John: You're right on the mileage. The plugs were burnt down to the porcelain on my 4.7 when I changed them I didn't see any change in mileage at all. Thankfully she does pull harder when I stomp on it at 100 km/hr.
