My truck is a gas pig. Any suggestions to improve my MPG?
I don't know what kind of gas mileage I'm getting yet in my 1999 Mazda B4000 that I bought last Monday, but what I do know is that I filled it up for the first time last Tuesday and had to get gas in it again yesterday (Saturday). I got about 250 miles on that first tank of gas (just normal street and highway driving) but had to fill it up again only after 4 days of driving it.
It cost me about $50 each time I filled it up.
My truck is a 5 speed auto. 2W / 4WD. 4.0L SOHC V6 Engine with 100K mile on it.
Is this typical? Or is there a problem that's causing it to eat gas like crazy?
Thanks!

I changed out the pcv valve(uber PITA), air filter, fuel filter, oil and filter change, 02 sensors, and a radiator flush a couple weeks ago and my truck felt healthy...so to speak....but didn't really help the fuel economy.
I've got JBA headers and the flow 40 out the side, stock airbox with twice the opening than it should be, reloped cams. I dunno wtf my trucks problem is. Just likes putting a hurtin' on my wallet.

But the damn EPA sticker says 16/18
Even my last 03 that I bought new only got about 15 at the max bone stock being a gereatric accelerator pedal operator.

how do headers, increased flow out (via. exhaust) and increased flow in (via. intake) increase fuel economy? I figure the increase in power is offset by the fact the the increased air is compensated by increased gas by the ECU so you get the appropriate air/fuel ratio for combustion.
do you have to drive up and down a lot of hills?
how much of your driving is highway?
do you have an automatic?
is your driving style granny-esque?
are you calculating you gas mileage correctly? (number of miles driven/fuel added*correction factor for tires)
all those things can add up and make your gas mileage worse

don't you have oversize tires, both in diameter and width?

......and yes I know how to properly calculate mpg =] lol

You're right. I didn't do my homework on this thing.

I have a 4.0 SOHC (bone stock) and if I stay off the pedal, I can get just over 20MPG on the highway. Everyday driving I average a bit over 16MPG - that's mixed city and freeway driving. I could probably get better mileage around town, but I have a heavy right foot. Apparently not as heavy as most of the folks posting here though...
