actually i meant to say dividing the mileage with total gallon filled after the low on fuel light comes on.

My military HMMWV we did a fuel injector mod ended up with about 2-3 mpg. But that bastard ripped lol.

Arch Stanton Anyone have the Fitch Fuel Catalyst? JP Magazine claims it works. I guy who has one on his ZJ said it worked, but then again he works at 4wheelparts and may have be trying just to sell me one.

TJNewbie if you've changed your tire size but not your speedo gear, you're not going to get the correct mpg's

jeepstertj well i know a few tips for you.
1.- remove all the weight that you can like tools, rear seat, or like that.
2.- inflate your tires 33-34psi
3.- Anticipate, coast, and use your brakes less. Look far down the road ahead, even if "far" means half a city block. Get into position for turn-lanes smoothly and early so that you don't have to accelerate to get in front of traffic. Anticipate stops or slow-downs ahead and take your foot off the gas: try to coast much more than you brake
4.-Don't accelerate quickly
5.-Use Cruise Control.
6.- i hear the tj max mpg point is at 50mph every 5 mph more your loss like 5%
7.-Switch to best-quality synthetic oils and filters throughout your drivetrain: engine oil, transmission fluid, differential gear oil and wheel bearing grease
8.- Keep your windows rolled up at speeds over 40 mph
9.- keep your engine well tuned
10.- use aditives on your fuel.
other stuff
put 2 very powerfull magnets on your fuel line you can see this in youtube (i dont know if it works but they said it works)
use hi flow air filters
change your fan to electric fan
OR PUT AN HHO generator a good friend put one of that in his montecarlo 305 and its getting like 27 mpg or more

SoGaJeep 1. Siphon all the gas out of you tank.
2. Measure out one gallon of gas and pour it back into to gas tanks.
3. Place gas can with extra gas in back of jeep.
4. Reset trip meter.
5. Drive till you run out of gas. "Coasting does not count as mileage"
6. Check mileage on trip meter. "Mileage showing is your miles per gallon"

I just had to say this....

Jondalar I checked mine once and forgot about it after that. 15.1 in my stock 2000 Sahara, 6cyl, stick. My daily driver before this was a Ranger 4.0 6 cyl stick and thats all it got too. But the thing is--that I love this Wrangler a bunch more.

BLK00TJ My Garmin has a milage/fuel app on it. I just enter the price per gallon and amount added and it computes the mpg using the distance traveled since last fillup. It also tallies total paid in fuel but I'm afraid to look at that readout since I put on 100 miles a day.

Thanks a bunch!
Next time you fill fill up reset trip a on your odo. Then when you fill up again take the miles you went in trip a and divide it by how many gallons of gas you just put into the jeep, and there ya go, rough estimate of mpg without being able to really do an average

I don't have a clue what my fuel economy is on my Jeep....I have never checked. BUT, I do think it is a good idea to know and campare just to be aware how it is running, to that end I have been guilty.
