Diesel Oils Evolve
The API CI-4 Diesel Oil
specification was introduced in December 2001 to protect against the higher temperatures and increased levels of acids, soot and oxidation associated with EGR engines. API CI-4 oils were formulated with increased detergent levels to protect rings and liners and increased oxidation inhibitors to prevent bearing corrosion. API issued an upgrade to its CI-4 specification, CI-4 PLUS, in September 2004 in order to provide improved oxidation resistance, shear stability, acid neutralization and soot dispersancy for EGR engines.
Some manufacturers released their own diesel oil performance specifications in order to assure optimum protection for their equipment. For example, Mack released its stringent EO-N Premium Plus High Performance Diesel Engine Oil specification in the spring of 2002 and upgraded it in April 2003 EO-N Premium Plus 03 and again in June 2006 to EO-O Premium Plus.
