BP Lubricants USA, Inc. announced its plans to introduce the newly formulated Castrol™ Hypuron™, a high-performance semi-synthetic diesel engine oil product designed for heavy-duty engines. The lubricant, formerly known as "Hypuron S", now complies with the new on-road industry standards for 2007 which require further control of exhaust emissions. Castrol Hypuron offers robust detergency to neutralize higher acid levels. The progressive formulation of Castrol Hypuron surpasses the ideal performance requirements of multiple engine manufacturers.
