I got a new OEM compressor ,drier, expansion valve and condensor from internet . I don't know if I need to pour the oil out from the OEM compressor and refill it with correct amount ? I understand that Lubirication is critical to the system and don't want a premature install, anyone has any suggestion?

Thanks

 

yea dump it and after install goto autozone and buy one can of pag oil i believe its 8oz.... its just like adding freon but after you fill it with oil let sit for about 2hrs to get oil to settle then add freon.
