Any shed should have an F-Gas certificate, the fines for a commercial establishment breaking these regs are severe. Depending on the A/C compressor in your vehicle, you may need to change the compressor oil more regularly. Once you have ascertained the approximate amount of oil that's been blown out you could, if you really want to, remove an amount of oil.
Fluorescent, fully synthetic air conditioning system oil based on polyalkylene glycol is highly compatible and miscible with R134a.

Due to the great variety of different applications and storage and processing conditions, we cannot guarantee a particular application result. To ensure that the compressor is lubricated correctly when it first engages, you should make sure that the correct amount and viscosity of oil is used. They are fully synthetic polyalkylene glyocols with specialised additives and are well suited to automotive aftermarket use. The most common lubricant used in automotive air conditioning systems is Polyalkylene Glycol oil, commonly known as Pag oil.
Generally, you should be looking to re-gas your air con system every two years, as it naturally leaks gas over time. When you blow through the system remove the drier before connecting the line from the Nitrogen to the system. One has to be careful when putting the system under a vacuum as it is possible for some air to be drawn in through the compressor shaft as it was designed to stop and leakage of oil to the atmosphere. To top up or replace the refrigerant oil in passenger or commercial vehicle air conditioning systems, it is poured into the special filling cylinder and then added to the refrigerant circuit via the air conditioning system filling device. The oil film also keeps the rubber seals in the refrigerant lines and connections supple and reduces diffusion.
PAO Oil (Polyalfaoleifin) – A mineral synthetic oil commonly used in car motor vehicles, PAO has low hygroscopicity properties and won’t introduce unwanted moisture when added to the system. POE Errecom synthetic lubricants, in each of their viscosity index, are made from a blend of polyol esters and additives specially formulated to obtain better lubricity, chemical and thermal stability and excellent Anti-wear protection of A / C system components and refrigeration.

They mix badly with Hydrofluorocarbons (HFC) such as R134a, and whilst engineering and technological advancements have raised the bar on lubricant performance, it’s the synthetic market that has forged ahead.
When your vehicle lacks compressor oil and you continue to use your air conditioning, your compressor can start to smoke. For example, if your car’s A/C has broken seals from a lack of compressor oil, you may need an A/C recharge to refill refrigerant levels. You should have a sticker on the top of your n/s wing under the bonnet detailing the amount of refrigerant. In my experience when I've fitted compressors I've never added or removed oil from the system, when I know the nature of the original compressor failure. For example, older cars with matching compressors will likely need more lubrication for their A/C compressors to work smoothly.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. Adding too much dye or other additives will also affect the lubrication effectiveness as this will dilute the Pag oil and have a detrimental effect on the compressor. 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. 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. 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?
