Its a common thing to all American vehicles. After a certain mileage they start consuming more oil which leads to over consumption of gas.
Take the car for a service. I know what you're going through, I'm currently there myself.

Sounds like one of 2 things. O2 Sensors or MAP sensor. Check those things.To find out if it's the O2 sensors you have to get the car to rev up past 2000 rpm. I had a 91 pontiac that did that and I changed the MAP sensor,still heavy black smoke.Revved the car up past 2000 rpm and found the O2 sensors bad.Changed the O2 sensors and problem fixed.

Make sure the cap is tight and recheck the oil level to make sure you didn't over fill it. You may have knocked off the hose that goes from your valve cover to the air cleaner. Ther is also a filter called the crank case filter that this hose goes to. Make sure it didn't get dislodged at the air cleaner.if it's coming from the tail pipe make sure you didn't over fill the oil pan.

numerous reasons, but it could be bad piston rings, a bad valve guide in the cylinder head.....or you could of spilled some pil on the exhaust manifold while changing the oil and it will clear up in a few days

It could be that your jeep needs servicing or it needs rigs, thats those things that go around the pistons.

You may have put the wrong oil in, or forgot to screw the oil cap back on tightly, or you may have overfilled your oil. check your levels, if they are ok, get your jeep to a trustworthy mechanic!

Sounds like piston rings, this can be checked easily using a compression tester.
