87 jeep Cherokee 4x4 auto 4.0

I'm sure we can squeeze 16 mpg out of it

I have replaced the spark plugs and air filter,  changes the oil.  Perform induction service and put premium with fuel cleaner,  I know replacing "good" parts is against the rules but we will see how it goes

Yes in line 6 auto,  I knew that the milage was bad when I bought it but it beats the Mercedes with no payment and liability I can afford the gas,  a bunch of guys at work have then and I wanted to follow,  I have never had a 4 wheel drive I could take off road and have not owned an American car or truck in 15 years

We had a few Jeeps growing up, a 1988? Cherokee (Last year AMC), that had the straight 6, it was a great car.
I learned how to drive on a '77 Golden Eagle CJ7 had like 33's on it and a suspension and body lift.  I'm 6'4" and I had trouble getting in that thing.  It was a Blast to drive up in though, the girls loved it.

That's never fun, but Pics or it didn't happen!!!

LOTS AERODYNAMIC STUFF IN THIS THREAD.    SC

About 3 years ago I was reading a article in a German auto mag. about aero stuff. They ran test on different auto/trucks. Get this, They found that a VW VANAGON had LESS wind resistance at 70mph than a 911 Porsche. What!!!  They ran more test and again the Vanagon was slicker.  Look at submarines. The cigar shape was much slicker than the WW-2 knife like hulls.  Just because it looks less resistant doesn't mean it is.  A stock VW '64 bug has a faster top speed than a stock '65 Bug .  Why ?  The windshield on a '65 Bug is about 2" taller.

I guess I am going to kill that idea by lifting it 3 inches,   Seems to be doing better after tune up induction service and o2 sensor

SC knows not of this "tune up" you speak of.  Scrap aluminum and no alternator belt is a much better solution to your mileage woes.
