A moderate-detergent monograde mineral engine oil specifically engineered for classic vehicles and also suitable for vintage applications, including those fitted with modern filtration systems. The formulation incorporates ZDDP (zinc and phosphorus) to provide essential anti-wear protection for camshafts and other highly loaded components.

Recommended for vintage engines where a monograde oil is specified and where the owner is satisfied that the crankcase is free from accumulated sludge and debris. It is also suitable for later vehicles equipped with improved oil filtration systems that were originally designed to operate on monograde oils containing detergent and dispersant additives.
