Engine oils are being introduced into the market place which utilize Group II or Hydrocracked base stocks.  The manufacturing process for these base oils removes contaminants, such as sulfur, nitrogen, iron, and other materials normally found in conventional solvent-refined base oils.

Advantages of hydrocracking technology may include longer lubricant life, fewer deposits, less maintenance, increased uptime and, under certain conditions, extended drains.  Some factors which may affect lubricant life are high oil temperatures, presence of water or dirt in an oil, entrained air, loss of additive performance and contamination from combustion byproducts.

Products formulated with Group II or Hydrocracked base oils have shown advanced performance in the areas of oil oxidation, thermal degradation, and stability.   However, it is important to remember that dirt from the environment, unburned fuel, and other contaminants will play a key role when extended oil drain intervals.

For years, Universal Lubricants, Inc. has designed engine oils to perform over an extended life. We will continue to provide our line of premium engine oils formulated with conventional base stocks (Dyna-Plex 21C SHPD, Universal Dezol). We also provide Dyna-Plex 21C Durazol HC Engine Oils formulated with hydrocracked (Group II) base oil and tailored to reach an unmatched level of performance.
