Do you mean just put e85 fuel into your stock cherokee? No. It needs to be
an engine specifically designed to handle that fuel. Or, do you mean put a
flex fuel engine into a cherokee? If so, why would you want to? e85 has so
much less BTU capability than regular gasoline and your fuel mileage goes
down accordingly. So you need to put in more fuel to go the same distance,
and are therefore putting MORE polutants in the air, not less. True, it is
lessening our dependance on foreign oil, but IMO the bigger problem is
polution. Go diesel--it's the fuel of the foreseeable future, or at least
it should be--again IMO.

Nope!
On the Renix (up to 91 I believe) XJ Jeeps as far as I know, you cannot
use 'any' alcohol or wood alcohol mix of any kind in it.
The owners manual for them warns that occasional use of up to 10%
alcohol will 'only' result in 'significant fuel system corrosion' and
may cause driveability issues.
The CJ7's owners manual forbids it totally. You are only supposed to
put in enough to get to real gas if you have to. Any alcohol mix in the
258's makes them run like pigs too so the YJ 258's up to 91 are the same.

Possible, yes. Advisable, no.
In the stock xj it can eat away a lot
of the plastic and rubber fuel system.
Plus the engine is not set up for the
correct timing and compression required
to efficiently use ethanol fuel.
To do this your looking at changing out
the fuel system, different injectors,
highly advanced timing and even increasing
compression (stroking) the engine.
Keep in mind that E85 is no good at all
in cold weather. You will need gasoline
to start and warm the engine up. That's why
some E85 vehicles have a small 1/2 gal gas
tank.
Now, think about the prior paragraph. Increased
timing and compression plus gasoline = *paff*
so the computer has to be able to detect what
the engine is running to keep from grenadeine.
There is a discussion here.
http://www.jeepsunlimited.com/forums...d.php?t=819380
The key item is E-85 reduces your economy by about 25%
i.e. rather than getting 20mpg you will get 15mpg. So
any cost savings in $/gal are wiped out.
Long story short.
Ethanol belongs in the pub, not the pump. :)
