Oh and if your wondering if you can put the bigger 20.5 gallon tank in the early models,you can but those tanks cost about $600 just for the tank alone.
They are only plastic..........geeeezzz. Must be "magic plastic". haha

Mandated by federal law,plastic tanks don't create sparks if puntured.Plus the plastic tanks will take alot more abuse before leaking then a steel tank can.


Oh and yes it is a very high grade plastic.

I get about 13 - 14 mpg city and 20.1 highway (on average). I have a 2002 Jeep Liberty Renegade (skid plates and lights. Total weight at about 5,630)

Looking to mod the air intake and new spark plugs. Should increase power and mpg

If your jeep / any car is rated at 87 octane shouldnt you fill it with that? Not 91? The higher the octane the slower the burn, but its the same amount of power generated usually. So if the computer injection is set for 87 doesnt anything higher leave residual gas in the exhaust vapor? And eventually cause your catalytic converter to die?

Thats what I was always told. Not sure if its true?

I'm chipped plus it is stated in the manual to use higher octane gas for towing and basically I'm always "towing" 2000lbs around all the time as my KJ tips the scales at 6000lbs now(stock was 4000lbs).The mid grade gas here in Colorado is only 87 octane and I get some pinging using it so premium it is with zero issues in my case.

Oh and I have always used premuim gas and I had it tested(emission tested) about 2 years ago and the place thought there machine was broken it tested with very low #'s,they recalibrated and tested again with the exact same #'s so no harm in my case from running premium.

About the same for us!

When it's all highway driving we manage about 23 miles per gallon.

I thought my Libby is bad, I guess there are worse. But still, I have a 03 liberty with over 200,000 miles on it, and I am only getting about 300/tank of gas on highway (And that's with a fresh tune up too)

Depends on what type of driving but on average with all city 275-320miles before the light comes on. All depends on if Im hauling stuff or sitting in traffic. As for traveling I have gotten up to 25MPG and seen 400+ for a tank, but for the most part I average 18-23ish per gallon.

Ha, this is old, but I guess I will reply. I put in right at 19 gallons during a "full" fill up.

Most of the time it is 240, but that is all highway. On an all-highway run to St Louis last month I pulled 320-something. Before the mods I would get 320 combined, and 360-380+ highway.
