Designed to last longer than plain 15W-40 oils Formulated to meet the needs of older engines with wider tolerances Higher lubricity

High temperature stability, withstands overheating situations preventing rupture Resists breakdown from solvents in diesel fuel, unlike regular 15W-40 blends Excellent for use in gasoline or diesel engines

High detergent action, holds up to twice as much contamination in suspension without compromising lubrication qualities Longer drain intervals Less oil consumption Higher oil pressure
