LIQUI MOLY PAG Air Conditioning Oil 46 | 250 ml | Compressor Oil | SKU: 4083

Product Information

Hello, As a recently retired refrigeration and A/C engineer there will be certain criteria you will need to follow to ensure a good result.

Using the wrong oil in hybrid vehicles may allow current to short circuit back through the A/C compressor, creating a shock hazard. MRL85 is compatible with all compressor types, including hermetic and other electric types, whose manufacturers specify the use of a modified POE lubricant of this ISO grade. This, coupled with the fact that the compressor is pre-filled, will help to ensure a best-practice repair, whilst saving garages both time and money.

A visible refrigerant leak is a sign that you need to take your vehicle to a car A/C compressor mechanic.

As the compressor may have discharged some crap into the system when it failed I thought it best to replace the receiver-dryer and condenser too. Since the absorbed water remains both hydrogen bound to the PAG’s ether linkages and non-reactive with the PAG, this property is actually beneficial. Mahle Air Con Compressor Oil (ACPL23000P) PAG ISO 100 YF 250ML is a Premium Line product that matches or exceeds OE-quality specifications, delivers peak performance even under extreme conditions, and is designed to last the vehicle's entire life cycle. Compressor oil is one of those crucial aspects of a car’s air conditioning system that many drivers may be unfamiliar with. Generally, you should be looking to re-gas your air con system every two years, as it naturally leaks gas over time.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. This new lubricant has been specially formulated to work in all types of vehicle air conditioning systems. Controlling the internal temperature of your car can help improve visibility, for example if your windscreen fogs up.

The information in the following tables has been compiled using data from vehicle manufacturers and other sources, and it is applicable only to air conditioning systems in their original designs. But again, I've never taken oil out of a new compressor, but if pushed I would remove about an egg cup full from the new compressor. 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. Considering 134a will evaporate at about -25deg ish, you DON'T want any contact with your skin as "freeze burns" are quite painful.Because car air conditioning compressors are complex systems, it’s not wise to change the compressor oil yourself. Choosing the wrong compressor oil for your car can result in improper lubrication, causing more damage to your vehicle’s A/C system. Due to their good miscibility with refrigerants are the best choice for applications with HFC / FC R134a, R404A, R407C. And because it does not absorb moisture, it is also used to lubricate O-rings and seals in both R-12 and R134a systems.

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. My near final bit of advise is to fit the compressor and then leave the rest for a A/C engineer to purge the system, replace the drier, leak test and then vacuum the system. Providing high lubricity and chemical stability with system components, POE also offers good miscibility (the ability to mix with refrigerants and HFCS). There should be an ID plate on the compressor body that will inform you of the amount of oil that should be in the compressor body.The compressor is one of the most important components within the air conditioning system, as it in essence, drives the refrigeration cycle. Any questions just ask, I have the time this week as I have COVID and I am self isolating, it's a real joy.
