New Multigrade SE/CD Lubricant 740523

A new 20W-40 multigrade oil that meets SE/CD specifications promises to perform satisfactorily in both gasoline and heavy-duty diesel engines. It permits easy cold starts, and it has passed the Caterpillar Tractor Co. OL-1 and the Mack T-1 tests and all of the SE/CD test requirements. Comprising a low-viscosity base stock blended with a V.I. improver and an improved detergent-inhibitor additive package that minimizes ring sticking, this oil is probably the forerunner of a series of SE/CD oils with even wider crossgradings.
