When it comes to Diesel engine oils, you have all kinds of options. However, only one option is recommended by Detroit Diesel Corporation (DDC)–using PowerGuard oil. These oils have been specially formulated for Detroit Diesel engines and in most cases actually exceed engineering specifications. Detroit Diesel engineers work closely with ExxonMobil chemists to create an offering of lubricant oils designed to match the needs of a wide range of engines. [PRWEB Aug 7, 2005]
