Well it does need oil, but too much will be as bad as not enough. I know that doesn't sound like much help, but I didn't know if you were aware of it.
I don't have A/C, so I don't know what kind of compressor yours has. Back in the old days I worked as a service tech for Volvo, and some of the vehicles used a York piston style compressor, and some used a rotary (Sankyo, I believe they were?) style compressor.
The York piston style that we used were mounted upright (I think some Jeeps use them laying on their sides?) and we actually had a dipstick that was inserted into the side of the compressor body to check the oil level.
The rotary style did not require checking the oil level in the compressor, but we did have to use one of the small diameter (1 5/8") cans of oil while recharging the system.
I would definitely research the oil level requirements, especially if you have the York style compressor.
Sorry I couldn't be of more specific help, but I hope that some of the general info that I can give you will help you find out the correct answers.
Please post up anything you find out, and your final results too.
