Study of Non-Phosphorus and Non-Ash Engine oil 2011-01-2127

Engine oils normally contain calcium detergents and ZnDTPs to have detergency and antiwear performance. However, it has been recently understood that these additives could deteriorate filter performance in catalyst and DPF. In this background this paper explains the study and the development about new type of engine oil excluding metal detergents and phosphorus compounds. The developed engine oil shows good durability in several JASO engine tests and a fleet test by formulating newly developed additives as substitute for calcium detergents and ZnDTPs.
