Fluorescent, fully synthetic air conditioning system oil based on polyalkylene glycol is highly compatible and miscible with R134a. Such duties and taxes are beyond our control as they are set by the Customs Authority of the destination country and depend on a number of factors, such as country of origin of the purchased product, local VAT rates and local import taxes, and it will be your responsibility to pay them if and when asked to by your local authorities. PAG 46 oil is the correct specification lubricant for both reciprocating and rotary compressors, although there are even differences with this designation, as the formulation will vary slightly depending on whether the system uses R134a or the newer, more environmentally friendly, R1234yf refrigerant. metric tons) for which a type approval was issued within the EU as of January 1, 2011, can therefore no longer be filled with R134a.

If you do, you might risk damaging your car’s A/C system by opting for the wrong compressor oil or mishandling the various parts. They have been developed to provide optimum miscibility and compatibility with HFC refrigerants such as R-134a and R404A and can also be used with HCFCs such as R22. For a pound more I would certainly recommend the longer lines, you don't want to arse around trying to place the set of gauges on some vibrating engine part when you can hook it onto the bonnet catch. The oil film also keeps the rubber seals in the refrigerant lines and connections supple and reduces diffusion.

Any shed should have an F-Gas certificate, the fines for a commercial establishment breaking these regs are severe.

Generally, you should be looking to re-gas your air con system every two years, as it naturally leaks gas over time. The fixed displacement compressor, the oldest design, features a set swash plate that operates the pistons necessary to generate the throughput of gas, at a constant volume per rotation, so has to use a clutch pulley to allow it to, in effect, be switched on or off when the air conditioning is or isn’t required. MRL-85 Vehicle A/C Oil is a premium Polyester-based mobile air conditioning lubricant formulated and additised to lubricate all belt driven and electric compressors with R134a or R1234yf refrigerants. The TT AC system has a total PAG oil capacity of 135g but with a newly drained compressor and new condenser/dryer, how much should I put in?

If you hear humming sounds, smell a burning odor, or see smoke when you turn on the air conditioning in your vehicle, you may need to get your compressor oil changed. Most times this will involve draining and measuring the oil from the failed compressor, then adding a specific volume of new oil to the replacement compressor.

You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. For the optimum performance, it is crucial to use just the right amount of oil too – a process known as oil balancing.Our ASE-certified mechanics can routinely check your car’s A/C compressor oil to make sure it gets changed when necessary. The compressor is one of the most important components within the air conditioning system, as it in essence, drives the refrigeration cycle. Refrigerant burns at a -30deg onto open skin is nasty, everything will be covered in oil, you don't want oil or refrigerant in your eyes, refrigerant liquid will blind you. One thing I’ve always been interested in “hacking” - the aircon won’t run below 5C ambient temp, which has always felt a little high to me as misting and condensation in cold weather are a pain, especially in the winter months here in the UK. 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.

When there is little to no lubrication in your car’s air conditioning compressor, it may smell like something is burning. 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. A rough rule of thumb is half for the compressor, a quarter for the condenser and a quarter for everything else.There are still numerous vehicles on the market with air-conditioning systems originally designed for refrigerant R12. 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.
