I toasted my AC compressor, i got a new one and a a bottle of oil. There are no instructions so how much oil do I put in the compressor?

I believe it should hold around 7oz from what I read a while back. In my experience though new compressors usually come pre-filled with oil, maybe yours isn't though.

No, there os a sticker on it that says it contains no oil

Correct the oil has to be filled in the compressor. Typically the PAG oil is sold in a 8 oz bottle. The compressor holds 7.1 if I remember correctly. The tag on the compressor should state the amount in cc's. The fill plug is in the side of the compressor. Just remove the plug and use a small clean funnel to pour the oil in. I added the full 8oz to mine. I spilled maybe 0.2 to 0.5 oz of the oil with the air coming out. But I've been good to go.Double check the lines to see there is no black death in the lines if so then the rest of the system has to be flushed. The flushing solvent is rather expensive.

I got the bottle of PAG, 8 oz. i havent looked at the compressor real close yet, just noticed the sticker saying no oil in compressor. On a sode note, after i install the new compressor, do i have to vaccume the system, really? Or if i just unhook and hook up the lines and recharge will it be ok. My system worked great, just the clutch took a dump on me.

Yeah. You got to pull a vacuum on the system to be sure there is no moisture in the system and to dry out the system because moisture will freeze and and plug up the system. Not good...
