Rule of thumb is, empty old compressor and measure oil..........if less than 2 oz., empty new one(some come full, some come empty), and add 2 oz.

If old compressor has more than 2 oz., add the same amount to the new compressor....

I ended up pouring the 8 ounces out of new compressor and adding about three back. Not sure if there is really a rule when installing a new compressor ?
Adding oil to an AC system is tough to gauge.
We have no clue what was lost.
Too much is horrible, as is too little. That part has always been a mystery to me. We never know what all has been done to a vehicle before we get it.

I like your 2 ounce adding tip Gus, the only one problem as I mentioned is what if the system was empty of oil before I worked on vehicle? The 2 ounces would not be enough.

Still we have to use some formula and yours is the 1st time anyone has ever told me one. THANKS. I will try and remember that one
