Its "Mineral Oil".
An oil transformer is filled with PCB oil to better transfer heat from the windings to the outside case (and into the air).
Transformer oil is pure insulating oil.
The oil quantity in an On-load Tap Changer (OLTC) of a 100 MVA transformer can vary depending on the design and manufacturer specifications. However, a typical estimate for the oil volume in the OLTC can range from approximately 500 to 1,500 liters. The total oil capacity of the transformer, including the main tank and OLTC, will be significantly higher. For precise values, it is best to consult the transformer's technical documentation or manufacturer.
The basic difference between the air cooled transformer and oil immersed transormer is: If the heat generated in the transformer winding is capable of being swapped by the sarrounding ambient air without causing any problem to the performance of the transformer then its normally reffered as Naturally Air Cooled transformer or simply air cooled transformer. However when the capacity of the transformer increases, the heat generated in the winding of the transformer is more and the ambient air normally is inadequate to cool the windings and maintain the performance of the transformer. Its because of this reason the transformer windings are submerged in an oil tank. It has been observed that the hydrogen ions present in oil help to maintain the temprature of the winding of the transformer and thus overall performance of transformer.

The name of the transformer oil is typically known as mineral oil, which is derived from refining crude oil. It is used in transformers for its excellent insulating and cooling properties. Some transformers may also use synthetic oils or ester-based oils, which are more environmentally friendly and have higher fire resistance.
As well as providing a cooling medium, transformer oil is also used to insulate a transformer. As its dielectric strength (how well it insulates) is much higher than air, it means that components within a transformer that are at different potentials can be placed much closer together if they are immersed in oil. So, operating an oil-filled transformer without oil will likely cause insulation breakdown within the transformer.
