milage on xj
 

have a 1997 tj, pondering trading in my F350 crew cab for something a tad
bit more fuel efficient.
have a 20ft. pontoon boat to pull and 28 ft car trailer
what kind of mileage could one expect on the XJ with 4.0 & 3.7 ?
any recommendations on what to look at & what to stay away from.
thinking along the line of used

as always
thanks

Re: milage on xj
 

XJ's mostly have a 4.0L inline 6 that has the power. However the XJ only
weights 3100# and I think would be too light for your car trailer. Also
their fuel mileage might be better then your F350 but sucks at maybe 10-12
city to 20 highway depending on your driving style. I don't think the 3.7 V6
was ever used in the XJ. Last year for the XJ was 2001. I've recently gotten
a 06 Liberty CRD (diesel) and it's 4200# and rated to tow 5000#. The 2.8L
diesel has the guts to do the job and get the mileage you want. At 2000
miles mine is not broken in and has been averaging 20+ in all city short
trip, AC on driving. (double the 99 XJ). Once broken in, 5k or more miles,
owners are reporting mileage as high as 30's highway with the norm being
28-29 mpg..
They've stopped making the Liberty CRD's for the US in May but some are
still in the dealer's lots. It's possible to get them at a highly discounted
price. My 06 Limited stickered at $28,400 and I got $5k off, some report as
much as $7k off. Just get the extended warranty as they're having "growing
pains" like most diesels in the US.

Re: milage on xj
 

My experience with an `89 XJ and a `96 XJ, each with the 4.0L and auto
transmission, is that with normal routine care you should get about 18
to 20 mpg, unladen. Mileage goes up to about 22 on long, clean,
traffic-free highways and down with added weight.

Re: milage on xj
 

What do you put on that car trailer, and what engine does the F350 have in
it? A pontoon boat doesn't sound too heavy for the XJ, but I would hesitate
to recommend one without knowing what kind of iron you haul on that car
trailer, how fast and how far. Fuel mileage when towing will depend on
engine size, vehicle weight, total payload and aerodynamic profile of the
total package. I suspect that total payload and profile are going to limit
the savings you can realize by changing the tow vehicle. I am guessing
here, that you should be looking at vehicles with a small V8 engine instead
of the XJ.

Re: milage on xj
 

My '87 XJ would drop to around 12 mpg when towing a 20' boat. It was
way too much boat for the Jeep however.

I'd echo others in wondering how much you're trying to pull. The XJ is
very very light... it wieghs less than Wranglers, Hell it wieghs less
than some Mustangs.

That said it gets great fuel mileage for an SUV, bone stock I've gotten
22 to 24 MPG mostly highway from my 92 2dr 4.0 automatic with over 140k
miles.

Far from bone stock they still get pretty fantastic mileage my 94 4dr
has a 4.6 litre "stroker". That is a 4.0 bored 0.30 over with the crank
and rods from a 4.2 litre YJ/CJ engine for a longer stroke (thus the
term stroker) 33" tires, 4.56 gears, Detroit trutrac and factory front
limited slip. And it's an auto, and it gets 21 MPG on longer highway
trips if I keep my foot out of the gas. On average (including plenty of
foot in the gas, and occasional hard launches at lights, and mild 60-ish
MPH highway crusing) it still manages 18 to 19. This with a very
pleasing amount of power and torque that rivals an old convertable 5.0
mustang GT I had.

I had a hard time believing my mileage especially considering the gears
and tire size.

pleasing amount of power and torque that rivals an old convertable 5.0
mustang GT I had.

I had a hard time believing my mileage especially considering the gears
and tire size.

I'd echo others in wondering how much you're trying to pull. The XJ is
very very light... it wieghs less than Wranglers, Hell it wieghs less
than some Mustangs.

That said it gets great fuel mileage for an SUV, bone stock I've gotten
22 to 24 MPG mostly highway from my 92 2dr 4.0 automatic with over 140k
miles.

Far from bone stock they still get pretty fantastic mileage my 94 4dr
has a 4.6 litre "stroker". That is a 4.0 bored 0.30 over with the crank
and rods from a 4.2 litre YJ/CJ engine for a longer stroke (thus the
term stroker) 33" tires, 4.56 gears, Detroit trutrac and factory front
limited slip. And it's an auto, and it gets 21 MPG on longer highway
trips if I keep my foot out of the gas. On average (including plenty of
foot in the gas, and occasional hard launches at lights, and mild 60-ish
MPH highway crusing) it still manages 18 to 19. This with a very
pleasing amount of power and torque that rivals an old convertable 5.0
mustang GT I had.

Re: milage on xj
 

I towed a car trailer a few times with a 5.2L ZJ. With a station wagon
on the trailer, it was a bit much weight but it got down the road.
Brakes were totally inadequate and I'm sure the XJ is the same.

Moving down from a 1-ton, you'd hate it. Keep the F350 and buy a
moped.

A buddy of mine has a Dodge 2500 Diesel with mods that dynos over 1000
ft-pounds and gets better than 24mpg. My Dakota gets 12.5mpg. Go
figure.

Some '86 AMCs had the Dana 44, but Daimler did away with that. I've
