Alternative construction materials, engines with catalytic converters or diesel particulate filters, and modern machining methods are just a few of the many technological developments that are only possible with specifically formulated lubricants or cutting fluids.
For instance, ceramics respond to additives in a completely different way than metals. Conventional oils and greases are only suitable to a certain extent for the lubrication of ceramic components used in piston rings, roller bearings, compressors, high-temperature gas turbines or other equipment. Modern materials can be produced more precisely and can therefore be more resistant to temperature and wear than metals. However, their precise surfaces with low roughness require lubricants that are „thinner“ and therefore more energy efficient.
In machine tools, metals are predominantly machined using emulsions of water-miscible cooling lubricants. A trend towards dry machining is becoming increasingly clear here. This involves replacing the emulsion by a very small quantity of a fully synthetic high-additive oil that is dispensed directly and precisely through the tool to the cutting surface. In the case of engines, catalytic converters and particulate filters make it possible to comply with evermore stringent emissions standards. However, for best results and trouble-free operation these components require low-SAPS motor oils. These oils contain a lower proportion of sulphur and phosphorous additives, which are considered catalyst poisons, and therefore generate fewer deposits. Low-viscosity motor oils that have been developed with energy efficiency and environmental impact in mind are set to play an increasingly significant role in the future as formulas must be adapted to comply with the further tightening of emissions standards.
