Many engineers and technicians who build and monitor machines show a certain reluctance to engage with the chemistry and technology of fuels and lubricants, even though these are essential operational or auxiliary materials. This is partly rooted in the prejudice that many non-chemists have towards chemistry, this "secret science." Such a prejudice is completely unjustified, as there is hardly any science that has as clear a system as chemistry. This is particularly true for organic chemistry. Furthermore, only relatively simple compounds are primarily considered for fuels and lubricants, which serve as the starting points for the systematic derivation of all organic compounds. This fact can be clearly explained by our natural...
