Environmental management costs caused by oil.
The advantage of vegetable oil is that it has low toxicity, lubrication properties and better extreme pressure properties than petroleum-based lubricants.

Another disadvantage is that it is easy to wax at low temperatures, and its oxidation stability is not as good as mineral oil.
