Product Information

For your car’s air conditioning system to work properly, it needs an adequate compressor oil supply. Only in time will it become apparent if all vehicle manufacturers agree on a single refrigerant, or whether different refrigerants will be used. To do this "by the book" the engineer will need an F Gas certificate, and if the refrigerant is not going to be reused, a waste certificate, and this will be required with any reclaimed oil.

Depending on the A/C compressor in your vehicle, you may need to change the compressor oil more regularly. Due to the great variety of different applications and storage and processing conditions, we cannot guarantee a particular application result.

Because the compressor comprises of moving mechanical components and runs at a high pressure and temperature, it is essential to make sure that the correct viscosity and quantity of Pag oil is used. Known as PS-R1, the polyether contains additional additives to protect against wear, oxidation and corrosion etc and offers excellent lubricity, thermal and chemical stability, making it ideal for both refrigerants.Choosing the wrong type of oil can negatively affect both the performance and longevity of the compressor. Most if not all OEM compressors will come pre-filled with oil, but it is up to the person installing the compressor to check that the correct amount of oil is in the compressor.

A visible refrigerant leak is a sign that you need to take your vehicle to a car A/C compressor mechanic.They are fully synthetic polyalkylene glyocols with specialised additives and are well suited to automotive aftermarket use. Scroll through this page and find out about the different variants of refrigerant and compressor oils. They are actually unable to form a long-lasting homogenous mixture and will separate after a short period of time when the compressor is not running. If there is a leak in the refrigerant circuit, the refrigerant lines of the vehicle can be examined using a UV lamp in a dark room. In short, there is no such thing as universal compressor oil, instead its formulation depends on the mechanism the compressor employs and the refrigerant it compresses.

Although unapproved as an AC lubricant by manufacturers, ISO 68 grade PAO is often used in the mobile aftermarket as a “universal” compressor oil.
