just got a helluva deal on this 03 3L edge its gettin around 18 mpg average, wat are some worth while gas saving mods?

wat are some gas saving mods
 
Manual transmission and proper gearing.
 
I modified my mileage by buying a tiny little shitbox, which paid for itself in 9 months. I got 36mpg my last tank and 39mpg on my best. My hog-truck stays parked unless I need to hual somethin'.
 
The basic tune-up, fresh oil, clean air filter and fuel filter. Also driving habit. Be kind to the pedals, take it easy. Proper tire pressure, clean fuel (not the E10 mix), no cargo or keep the truck light.
 
take that top off. but before anyone says anything im cover my tracks yes taking the top off reduces weight = better mpgs but then you have the air pushing against the tailgate either drop the gate or put a tonneu(spelling) cover on. 18 is decent for the 3.0 i got 20 once in mine 3.0 5speed 3.73 gears 235/75R15 wrangler radials and that was with easing it everywhere i went and 65-70 for 200 miles without passing any one but the occasional semi.
 
Its been proven, dropping the tailgate/ installing a tailgate net/ installing a tonneau cover will not increase mpg. Trucks are designed for the best airflow with the tailgate up, changing that adds more wind drag, reducing mpg.
 
i was getting 345 miles out of my 99 3.0 5speed 4x4 every fill up dont know what the MPG would be
 
I hate to refer a forum to a forum, but http://www.ecomodder.com is fascinating! These guys make fuel economy a sport, with vehicle modifications and driving habits. Read a bit, you'll be hooked. Unfortunately, as intrigued as I was, not much is going to help my 8000lb diesel pickup :icon_twisted:

Toppers help milage, they improve the aerodymanics of the vehicle. Note that BII's and Explorers usually get better milage than their Ranger counterparts.

Tailgate up/down benefits depends on the bed length and cab size. I have had pop bottles blow out of the back of my Ranger with a 7' box, but I still have leaves from last fall swirling around in the back of my F-150 with a much larger cab in front of a 6.5' box. A pickup cab will create a nice swirling action that is kind of like a fastback on a car, it just swirls there and more air coming over the roof just glides off the back of the swirling air... problem is with a longbox the tailgate catches it wheras with a shorbox the tailgate takes part in the cyclonic action too.

And I have heard of people driving with the tailgates down hitting a bump wrong and unhinging them.
 
18 mpg is about average for a 3.0. There isn't a lot you can do that will make a difference. I put a Gibson exhaust on my Sport Trac and picked up 3 mpg on the highway.
