Oil additives

[mojopt]

Anyone had any experience with additives such as Zerol Ice or Fridgi-tech. Both claim to improve the lubircity of refrigerant oil, thus saving energy(money).

Unless some miraculous product has been discovered, I was always of the mind that there are only two things that should be in a system- refrigerant and oil.
