I use a drop in R 12 replacement gas and it works great in several of my older cars. They say this gas will pickup and move both the new and old oils the same. Do you have any idea how much of this leak detecter oil I could add and NOT overfill the system. thanks....
A teaspoon or 2 will do it for the dye but you will need to determine how much oil your system/compressor requires.
