Anhydrous fluids and without volatile organic compounds, comprised mainly of mineral oils (derived from the petrochemical industry) and/or synthetic oils (derived from the synthetic chemistry industry). Neat oils are characterized by high lubricity and by variable viscosity depending on the length of their molecules (from 9 to more than 1,000mm²/s or cSt).

The main applications of oils are:

- engines,
- hydraulic applications,
- transmissions,
- general engineering,
- tempering of metals,
- machining,
- stamping.
