Super Tech 15W40 Universal Motor Oil is specially engineered for heavy duty diesel and gasoline engines operating under all service conditions. Today heavy-duty diesel lubrication needs are more demanding and complex than ever. Only the most advanced oils can meet the difficult challenge of effectively balancing durability, extended drain intervals and emission control. Super Tech 15W40 Universal Motor Oil meets that challenge. High detergency and superior dispersancy keep engines clean and soot suspended in the oil despite longer drain intervals and increased soot loading. Higher starting TBN provides added protection against acid build-up that can cause rust and corrosion. The Super Tech 15W40 Universal Motor Oil meets the following requirements: API CJ-4/SM; CI-4/Plus; CI-4; CH-4; CG-4; ACEA E&-04 Allison C-$; Caterpillar ECF-3, ECF-1, TO-2; Cummins CES 20081; Global DHD-1; JASO DH-2; MACK EO-O, Premium Plus '07, EO-N Premium Plus'03; MAN 3275; Volvo VDS-4, VDS-3, VDS-2.
