Save Money On Replenishing Bearing Grease!

Instead of replenishing bearing grease... pump oil into it: Fact or fiction?

If you’ve got an automotive aircon repair shop, the cost of carrying all the specialised grades of compressor oils is probably killing you? I’m sure you’ve thought about using a universal compressor oil; but could you use this in all applications?

With mineral oil, ester oil, and three common viscosities of PAG synthetic air compressor oils in use, one type of oil that will work in everything definitely seems like a logical approach.

However, is there really
