I just got done with my first tank of gas in the 97 and well I got 10.76 mpg. I need help with this thing. 4 banger 5 speed and I was driving is soft- ie shifting before 2k along with not even really speeding in the thing. It pissed me off tonite. HELP
well I went 164.4 miles til it was on the E- but the funny part was I put 10 gallons in it and it was full. Then drove it 18 miles home and it was at 3/4 of a tank. I am stumped. My 12 second car got better gas mileage then this thing!
I thought these things have a 15 gallon fuel tank?
Oh you must have the tiny fuel tank.. the funny part is jeep used the same tank, they just made it in a certain way so it only fills up halfway and stops like its full. They offered the jeeps with 2 different size tanks (same size tanks just one fills up halfway) If you want you can cut off a part so you can have the full tank.. search around the forum for more info...
Anyhow a good way to measure your mpg is set the pump so it fills up automatically, once it clicks, dont try to top it off, once it clicks, thats it.. anyhow zero out your odometer, drivewhatever you gotta drive and when your gas starts getting on E, fill it up and then take the # on ur odometer and then devide it by whatever you fill up as its said on your receipt.
example.. (these numbers are made up).. it says 186 on your odometer and you filled up 11.253 gallons...
That is what I did. When I bought it last week I filled it up with 15 gallons. Drove it 164.4 miles before it was on E tonite. So i figured I ran it to about 1 gallon left. I put 40 dollars in it tonite- and it was full then drove it 18 miles and it was at 3/4 of a tank. IF it keeps getting this kind of mileage a big block or something is going in it. Atleast I will know why my little tonka toy is drinking like a russian.
Triple - why would Jeep put a tank in that only fills 1/2 way?It doesn't seem logical - but some things don't.
Honestly no idea, perhaps so they can charge you extra for choosing the "bigger tank"?.. i donno.. its simple to fix though.. the filler pipe goes into the tank further down.. all you have to do is drop the tank, remove the pump and inside you will feel the pipe Cut it off at the top and you will have a 19 gallon tank.
If you're interested search around, there were detailed explanations on how to do it..
It is a fact I have read at least 6 deff web sites stateing the same thing.Trim 2.5"s off the filler neck and now you go from a 15 gallon tank to a 19 gallon tank.The tanks are the same but the filler neck goes into the tank deeper so the gas starts comeing out of the neck before the tank is full.Here are 2 of the links I have.I will look for the others.

Ok correction I said filler neck but it is the vent tube that goes into the tank deeper causeing the gas to come up and out into the filler neck before the tank is really full.
