keep the top up, doors on and AC on. i get about a 1-2 mpg increase (from 12-13 mpg i get with my 4.0/5sp/35"/4.88 TJ). may not be much but every bit helps.

My 99 4.0 5spd 3.73 gear 30 inch tire gets a even 20mpg. Took the hard top and doors off and it dropped to 19.1 go figure. Its all stock fresh tune up, 85k miles, i shift between 2kand 2.6k rpm.
I think I have a small crack in my exh manifold cause it feels like I have a slight lean surge at part throttle accelation. I just got a new manifold just and haven't got the time to put it on. If the milege drops when it is installed then ill know what it was.

So does a cone filter/intake (such as what xj-armor.com sells), high-flow cat-back (Flowmaster, lets say), splitfires and a better ignition actually help, or are they more of a plecebo effect with our 4L ho's?

I've been scratching my head with respect to putting in some or all of these mods but I wonder whether or not its worth it. I mean I'd rather not spend the money to gain a few horses but end up using just as much fuel.

All these things will help a little. The problem is that they are expensive enough that the payback period is going to be measured in tens of thousands of miles.

Check out this article:

http://cnn.edmunds.com/ownership/dri...2/article.html

... an informal test on some of the common fuel savings tips.

Check test #3... Take it easy on the gas pedal (like mentioned earlier)...

I tried it and my average mileage for that tank went up over 20% (I don't remember the exact numbers, just the final results).

Here's the funny thing--- It didn't take any longer to get where I was going! Most of the time, I'd get the "one finger wave" from the tailgaters as they passed me, but I got to chuck a cheezy "I'm getting 20% better gas mileage and getting there just as quick as you" grin as I pulled up next to them and waited at the next red light...

Think about it this way: They were behind you at one light, they speed to the next one and now their 2 cars ahead of you, that's a 3 car jump... We all follow the car ahead of us by 2 seconds (yeah right - but let's assume)... He burned 20% more gas to save 6 seconds? Not worth it to me!!! Lots of times, I'd even be ahead of them at the next light because of lane choice...

Keep the foot off the skinny pedal, your engine and your wallet will appreciate it... With a 15 gallon tank in my TJ, it was also nice to get an extra 40-50 miles out of that tank...

You could buy a 15 year old Honda Civic for like 600 bucks and only use the Jeep for fun stuff.

I know, crappy suggestion, but with gas at 3 bucks plus, what do you want?

I got a whopping 117.3 miles to my ENTIRE tank, in three days. City driving, under 2500rpm, light accelerating and coasting as soon as the light turns red (a/c off, weather's nice why use it?) and never once exceeded 50mph... WTH is wrong?!

BTW - using the a/c will drop your mpg MORE than driving with a window down, so if the weather's nice, drop the window. If a new Civic looses around 6mpg with the a/c on, I'd hate to think what it does to us I thought this was crap, so I tested it in my xB with the a/c on and windows up - 244.7 miles to the 12 gallon tank. Window down, a/c off? 281.1 miles... Used the recommended gas-saving driving practices both times, too

Better gas mileage

Two things I have found to increase my gas mileage was to throw on a cold air intake and a performance exhaust. My TJ went from 200 miles per tank to around 250-275....Also having a lead foot doesn't help

A cold air intake accually dropped my gas milage by 1.5 mpg. I guess every Jeep is different.

One thing I have noticed is when I put the top down I tend to get heavy with the right foot. I don't know why. Top down I have to go faster.

I end up going faster with the windows down because I like the sound of the exhaust and the tire howl... Also, if you're in a fuel-conservative mood listen to more mellow music... studies have actually proven that faster music (metallica and similar bands) causes drivers to grow lead feet

IIRC several jeep engineers have gone on to state that the stock intake is nonrestrictive, meaning there is more CFM that can flow through the stock setup than can be used at WOT.

you have a lot of addedweight in mods... did you regear for those bigger tires? if not i bet you would get better mileage if/when you do.

at highway speeds i think i get best mileage using the vent and keeping the windows up... the blower motor doesn't put hardly any load on the engine, and having the windows closed keeps what little aerodynamics it has. i think even if i ran my A/C, i would stil get better mileage than if i opened the windows. too much wind resistance. also i only do 65 or below, and i shift at 2000-2200 rpms

around town, aerodynamics don't matter as much because of low speeds... so window open tends to be the best.

i consistently get 21.3 mpg
