Could someone write a couple paragraphs (or more; the longer, the better) on ways to save gas in a Jeep. Air filter, fuel filter, synthetic, fuel injectors, etc. I'm currently averaging only 350-375 miles per tank (23 gallons) on a 4.0L engine. It would be ideal to get at minimum around 425.

lol dude your lucky. Im getting just under 200 miles per tank (roughly 12mpg). and thats a 2.5 mpg increase after I put on a 63mm bored Throttle body. BUT im running 35s on 3:55 gears

Yea don;t come in here braggin! Lol all kidding aside, all you can do is keep it tuned up and in good tire health. Jeeps were never built for gas milage it's something you just have to let go of when you marry her.

Your right foot is a huge factor in gas mileage. When I drive my XJ hard, wheeling, towing, just on the throttle, I am averaging 12.5mpg.

If I take it easy I can get 16mpg. I try to keep my RPMs under 2500.

Do a google search for XJ gas mileage. This is about as commong a topic as any

Haha exactly take the good with the bad

It's actually under 350. I was just going off the EPA and Jeep measurements of fuel economy. Says 15MPG combined, but takes about $78 to fill up (23 gallons) and I probably see only 200-275MPG. Something needs to be done. I _will_ find a way/s to save fuel. It's not impossible and I will do it. And forget buying a Honda. I'm a man. We drive trucks, not riced out automobiles.

Is that a brush guard in you profile pic??

when I added mine I think my XJ dropped 2 mpg easy. Streamline

Slow down. Period. I get about 22mpg driving like a grampa. Maybe 16 driving with traffic.

I average about 325 miles between fill ups, and then it usually only takes about 18.5 gallons, so I'm getting about 17.5 miles per gallon if I drive nice and don't sit and idle for long periods of time (stop lights, drive throughs, staring at the jr. high girls, ect.) I can deal with that kind of mileage because I'm more comfortable in my Grand Cherokee than I am in my 07 Kia Spectra that gets 35 MPG. 6'5" and 325 pounds does not fit into a tiny car too well, I'll trade off some fuel mileage for comfort any day.

idk if it applies to ZJs like it does to XJs but hi flow intake from 99+ xj and hi flow injectors out of a stratus or mustang. and like someone said lose the grill gaurd

mlyon83

Yeah, came with the Jeep when I bought it. Have been thinking of removing it, but the Jeep loses a more intimidating look as a result. Plus it could help during a vehicle accident. Maybe I should take it off to save gas. How much $$ do you think I could sell the grill guard for?

your gas milage sounds about right for how big your tank is. you might as well buy something new/newer if you want that good of gas milage cuz youre gonna spend A LOT of money if you are that determined to get the gas milage you desire. but i agree with everyone else on here its basicaly all in how heavy your foot it just consider that and drive like gandpa

mlyon83

Haha. Sounds good to me. Nice icon.

Id try out the awesome search engine... it might help...

Stay below 2000 rpm's, and dont go over 60 mph.
