What colour is oil?

Automotive oils are naturally clear, not the amber colour that people assume they are. The reason they are often amber coloured is due to a dye manufacturers add and is only added as people assume oils should be a certain colour.

There are many oils on the market that are various colours and it is due to the addition of different coloured dyes. The dyes have no actual benefit to the oil, other than making it stand out as different to the rest.
