Aloha guys. yesterday, I manage to remove my AC compressor (what a chore! it removes pretty easy, but you have to wiggle it around to get it out!) and as the manual states, I turn the clutch itself to get the oil out so I can put back the same amount it came out. Now, my new compressor is from 4 Season and it said it has 3oz of oil already in the compressor. What I remove from the old compressor looks to be way less then that 3 oz. More like 2oz, at the most. I do have cylinder that measure oil amount (I ride and maintain motorcycle as well) so I will get accurate measurement later (I'm on my lunch break now). Should I add little more oil in there or should I just bolt up the new compressor since the oil from old compressor had little less oil in it?
