Last summer the cycling switch on my compressor blew, and I finally got it fixed today. So essentially I havnet used my compressor in a year, and today when it started running again, it got stuck a few times. But it ran and did its job. However, I noticed that its bogging down the engine more, particulary at idle. I sense this is going to affect my car's performanace.

Would changing the compressor oil 1) be really worth it and 2)be really hard to do? have any of you done it? please post info if ya have.
