My gas mileage is so pathetic. 05 Screw, 2wd 3.55LS. Most of my driving is city, and short trips(5 miles or less) All I have basically is True dual straight pipes no muffler 2.5". Any ideas guys? Preciate it.

 

city driving and short runs are the worst thing you can do for fuel economy

 

I'm gonna suggest the gears are a tad too small, maybe not enough PSI, un-balanced true duals.

 

I still think I'd get 13? haha not sure.

Probably would make a killing on the highway with 3.55. I'm running 35PSI, I'm thinking of running it at about 38, not sure. Haha, you and the X pipe. I'll get it done sometime haha.

 

Anyone had any differences with the gas with Ethanol? I'm thinking of trying Chevron(apparently Ford reccomends) I did it once and got WORSE. Perhaps it was cleaning out gunk?

 

Hows it running have you changed your plugs?

 

chevron lasts longer with me

 

It runs fine. I mean it only has 17,500 miles, so no to the plugs.

 

Ah really? Do you always run it or what?

 

I'd say it's because of short trips with the 3.55 rear end. Like you said, highway driving would probably be much better.

 

not since i got it, but for a year. of course it depends how i drive, but it does last longer.. got my cuzin to try it on his explorer and it worked for him too

 

Yeah, can't wait to lift and re gear it. haha

 

I'd try it now, but the Chevron is 1.89 and everywhere else is about 1.75. Not sure I can bring myself to do 14 cents extra a gallon.

 

true

 

Especially with the fact that the one time I did try it, it went down. We'll see though. I need gas, I'm afraid to fill up. My gas mileage is going to be atrocious this tank!
