There are various PAG oils with different flow characteristics (viscosities) for use with refrigerant R134a. You should have a sticker on the top of your n/s wing under the bonnet detailing the amount of refrigerant. The most commonly used gas to recharge your air con system is R-1234yf refrigerant gas, and that’s exactly what we sell at Halfords. Adding a universal oil to Pag oil may cause lubrication issues for the compressor as the universal oil will not mix properly with the Pag oil and will separate.

We offer the world's widest, deepest range of motor and gear oils, fuel and oil additives, care products, chemical problem-solvers and service products. Packaged in a unique moisture barrier treated polymer bottle under a nitrogen blanket and heat sealed lid. Subject to the advice of the compressor manufacturer and the refrigerant being used, there are 4 main types of oil to consider.This gas is good for the environment, having a lifespan of just 11 days, and it lubricates the compressor in your air con system to improve its lifespan.

Everyone agrees that refrigerant oil is key to a healthy system; as well as lubricating the compressors internal components it’s also a heat absorber and sealing agent for rubber parts such as hoses and seals. 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. Is there a way - eg through coding, or adjusting the resistance of the outside air temp sensor - to have the aircon engage as low as eg 1C ambient?

When performing a compressor oil balance, it’s important to always follow the instructions provided with the compressor or in the vehicle service manual, to know how much oil to add prior to installation.
