I am working on installing an OBA system in my truck. I am going to be using the stock a/c compressor. I have done alot of research but have not been able find a satisfactory answer to the following question. How much oil does the a/c compressor need to be happy. I know I need an in-line oiler but how much oil does it need to out put. While I was reading i ran across multiple places where people said they kept having to replace their pump or the it would get extremely hot. I don't want to burn through pumps so any help would be greatly appreciated.

Thanks,
Troy
