Replacing a bad compressor and have the PAG-150 replacement quantities for the compressor and accumulator. I was wondering if it is also necessary to add a can of oil charge when replacing the freon? Seems like it should need some after being vacuumed out.

Add a couple ounces of oil in the compressor, the rest in the accumulator.. Vacuum does not remove oil, so be sure you don't over fill the system with oil..an ounce won't hurt it, but to much in the system will affect cooling.. Stay away from canned oil charges since the system is empty, add it to the compressor and accumulator before pulling your vacuum....

New compressors usually come with some oil inside, you should not use that oil though. During storage of the compressor, the factory oil could have absorbed water. Drain it, measure what came out and put back the same amount of new oil.
