I don't think the people that are servicing your ac have the right equipment when I service a ac when I suck the Freon out it will tell me how much oil came out with Freon if the system is empty add 2 oz. of oil
What is the equipment you use? That would be able to tell you how much oil came out? The only way that I know of to get an ACCURATE charge of oil is to pull the compressor, drain the compressor oil and then put the specified Oil volume charge back in the compressor. Other than that, it is GUESStimate. When you have a drastic sudden leak and it blows the coolant, then that will allow a certain amount of oil out. How much, you can never know. But as another poster stated, you could put an OZ or 2 in the system. I have NEVER heard of installing Compressor oil as a routine maintenance item on a Dash AC system. Doug
