2.8 VR6 (200 Hp) V6 engine.
First thing is have the AC charge checked by a shop, if that is OK then the AC compressor low side pressure switch may be defective or the compressor relay is defective.
if you are asking about the "air conditioning compressor" oil, then you need to add refrigerant with oil already in it. you can get a kit for that at most auto parts stores and they have the directions on them. if this is for some other oil, then please elaborate.
get a hayes or chilton service manual, they will help by showing the location and steps needed to remove and replace compressor. they cost about 20$ at autozone or oreillys.

Ignition Coils are to the side of their respective cylinders: Coil......CYLINDER......Coil
8->o--->|8............7|<----o<-7
6->o--->|6............5|<----o<-5
4->o--->|4............3|<----o<-3
2->o--->|2............1|<----o<-1

Look way down on the engine front area passenger side for the compressor. Is the belt gone? Check the belt tensioner pulley....can you turn it?....is it seized? If it is OK then try and turn the compressor.......and the idler part of the compressor. If the compressor is seized.....why? Usually lack of oil in the system,or an overcharged system.
Once you have removed the 134a gas from the A/C system before removing the compressor and before installing the new compressor make sure you add the correct amount and type of oil into the system to prevent another seized compressor after you have flushed the system to remove contaminates such as old compressor grindings......if the compressor was seized. You will also need a new receiver/dryer once you open the system to the moisture in the air. Do not expose the new receiver/dryer to air....install last. Vacuum the system well before refilling with the correct amount of 134a. At 70 to 80 degrees outside temp........a vent temp at medium fan speed of 48 to 45 degrees should be a full charge .......use this reading if you do not have a electronic scale and/or A/C machine. DO NOT OVERFILL THE SYSTEM.
You probably have bad bearings in the A/C clutch pulley. Remove the drive belt and spin the pulley for noise and shake it around for play. Any noise or play and you need a new clutch. Also see if the front hub on the compressor turns easy. If not, then the noise could be the compressor locking up. Reman compressor might be the least expensive route.
