Lubricants carry out other tasks essential for the effective functioning of the equipment:

- They reduce friction between two metal surfaces
- They protect mechanical parts from wear and corrosion
- They clean and cool
- To act as a sealant between the engine segments

The quality and performance of lubricants depend on the quality of the bases used, the improvements provided by the additives used and the physical-chemical characteristics of the finished lubricants.

Regarding the type of application, the most important oils are:
- Oils for 2- and 4-stroke engines
- Marine Oils
- Oils for transmissions and gearboxes
- Lubricating greases (bearings)
- Oils for industrial uses

All lubricating oils are made up of a base oil, usually derived from petroleum, and additives (compounds incorporated in small quantities into base oils to obtain a lubricant with the quality level and type of application appropriate).

The most important additives according to the function they must complete are:
- Antioxidant
- Anti-rust
- Detergent
- Dispersant
- Viscosity index improver
- Freeze depressant

The most important characteristics of the lubricants that define their class are:
- Color
- Viscosity
- Viscosity index
- Density
- Flash point
- Fire point
- Pour point
- Extreme pressure
- Aeroemulsion
- Demulsification
- TBN
