Cobra DIESEL motor oil is designed for all diesel engines, including heavy-duty and turbocharged models. This motor oil provides excellent engine cleanliness, prevents sludge formation, reduces bearing corrosion and engine rusting, as well as minimizes ringsticking and liner-scuffing. It also provides protection against extreme operating temperature oil breakdown and the formation of lacquer and varnish deposits.

Cobra DIESEL PLUS 15W40 is a blend of carefully selected premium quality base oils and exceptional performance additives. It is multi-purpose crankcase oil for all high-speed diesel and gasoline engines, regardless of operating severity and type of service. It is primarily intended for the performance and emissions requirements of line-haul truck diesel engines equipped with EGR (Exhaust Gas Recirculation). Today’s engines are tuned to produce lower harmful emissions. The effect is a higher operating temperature causing increased stress to the internal engine components and lubricants as well as increased soot levels. Increased soot leads to the formation of piston crown-land deposits and the tendency for regular engine oil to thicken causing plugged filters leading to abrasive wear and higher oil consumption.
