Engine Oils 4 - HC-Technology

In addition to the classical, partially and/or semi-synthetic oils, engine oils composed according to the HC technology (Hydrocrack) are used increasingly often.

Hydrocrack oils are produced from crude oil via thermal or catalytic cracking in hydrogen atmosphere and form the starting product for many multigrade engine oils. Hydrocrack oils are thermally more stable and provide for a more favourable viscosity and evaporability than other basic products.
