WAYNE, N.J. — BP Lubricants will 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.

The new industry standards set by the Environmental Protection Agency (EPA) mark the next official round of emission regulations tailored to on-road diesel engines. To assist engine manufacturers with compliance, Castrol has improved and expanded its premium semi-synthetic diesel engine oil line by redesigning Hypuron S to form Hypuron.

“Castrol will continue to be an industry leader by surpassing government regulations,” said Page Gray, Castrol brand manager. “With Castrol’s advanced technology, Castrol Hypuron is able to go above and beyond performance requirements of various engine oils.”

Formulated to maintain its high total base number (TBN), while meeting the low ash requirements of API CJ-4, Castrol Hypuron minimizes oil consumption, reduces piston deposit formation and increases oil film strength as demonstrated in over eight million miles worth of testing, noted the company.

Sulfated ash, phosphorous and sulfur are compounds found in lubricants that can affect after-treatment devices used to limit the exhaust gases from leaving newly designed diesel engines. Castrol Hypuron is referred to as low SAPS due to the low amounts of sulfated ash, phosphorus and sulfur contained in the oil.

Castrol Hypuron meets industry specifications, including: API Service Categories SAE 15W-40 (CJ-4, CI-4 Plus, CI-4, CH-4, CG-4, CF-4, SL); Caterpillar ECF-2; Cummins CES 20081; Detroit Diesel; Navistar International; Mack EO-O Volvo VDS-4.
