Ok, how about some info ?
you didn't STATE that you checked the oil, you did not state what vehicle this is, nor anything else that might be helpful.
IS this the TJ in your profile ? with out stating what you are working on, how does anyone know?
Could be a moped for all we know. DO NOT ASSUME everyone knows what you drive, or are working on.
Now, you are checking the oil engine off on level ground correct? does it show on the stick? at the proper level?
7K is quit e a ways to go on an oil change, an engine with mileage will start to burn oil soon after 3k.
after 5k, it'll almost double in consumption.
sure, the manufacturer states run it to 7500 mile on an oil change, but thats in a perfect world. reality work much differently.
I seem to remember that 4.0's had/have an issue with the oil pressure sending unit. may want to check that out.
