China is one step closer to launching its own diesel engine oil specification – D1 – after an industry committee in the country endorsed it at the end of September. Developers say they intend to write a full slate of domestic specs to replace the foreign specs that China’s markets now follow.
D1 includes four engine tests conducted on engines from four different Chinese original equipment manufacturers. The CA6DM3 test for oil performance under high temperatuers is performned on an engine from FAW Group. The DCI11 test for wear protection and resistance to soot deposits is conducted on an engine from Dongfeng Motor. Weichai Power contributed an engine for the WP13 test for alkalinity and wear resistance, while the 2.0CTI test for performance under fuel dilution uses an engine from JAC.
