New Castrol engine oil line

Castrol Heavy Duty Lubricants has introduced a new line of diesel engine oils designed to meet the needs of new Exhaust Gas Recirculation (EGR) engines as well as help improve performance of older diesel engine models. Castrol's Enduron S, Tection Extra, and Tection S, are part of a major rollout of products designed to meet engine oil specifications developed by the American Petroleum Institute (API)

Castrol's Enduron S, Tection Extra, and Tection S, are part of a major rollout of products designed to meet engine oil specifications developed by the American Petroleum Institute (API) for new low-emission EGR engines due to arrive on the market in October of this year.

Baltimore-based Castrol said its Enduron S and Tection Extra meet API's CI-4, CH-4, CG-4, CF-4, and SL engine oil specifications, as well as Cummins' CES 20078, 20076 and Mack's EO-M requirements. Castrol's Tection S meets current diesel engine oil specifications and API's CI4 requirement.

Enduron S is Castrol's top grade product from its new engine oil line. It's made from a synthetic blend base stock, is designed to produce low levels of ash, has higher detergent properties to neutralize higher acid levels in EGR engines, and will not compromise performance if it's used in older diesel engine models.

Tection Extra has almost the same performance characteristics as Enduron S, except that it does not have the same level of viscosity control that Enduron S has. Tection S represents the low end of Castrol's new engine oil line, providing soot-level control EGR engine compliance and standard capabilities in terms of engine component protection.
