My 1994 YJ got 21 MPG in July when I bought it. Now it might get 18 MPG with
the winterized fuel. 193000 miles but it needs a new coolant system parts
and the thermostat needs replacing. I don't want to do that until I get
a new radiator, hoses and clamps. The water pump is still working but I
will probably replace that too. Once that happens a new stat will build
up the pressure and the operating temp which will help the ECU work out
the mixture better.

Re: 2003 Wrangler 4.0L - gas mileage
My '03 Sahara is seeing about 15mpg. Now, for the most part it drives 10
miles to work daily, barely gets warmed up in the process, and is driven
'aggressively'.
I've tried to do worse and I have not seen lower than 14.5mpg.
If I religiously shift when the idiot light tells me to and press the
pedal like it was an egg then I get 18mpg around town. But it's no fun
to drive that way.
Last- when it first got cold out I had to switch to 89 octane to prevent
pinging at wide-open-throttle on the highway. That resolved itself after
a couple of tanks and now I can run 87 again. Perhaps there were carbon
deposits or the computer had to learn about oxygenated gas?

Re: 2003 Wrangler 4.0L - gas mileage
Barely gets warmed up, and driven 'aggressively'? That doesn't sound
like a recipe that will result in long vehicle life. :)
