Phillips 66 Lubricants, a division of ConocoPhillips, has introduced a new oil formulation to protect heavy-duty diesel engines that meet United States Environmental Protection Agency emission limits. Phillips 66 Super HD II oil is now formulated to exceed the American Petroleum Institute's new CI-4 specification.
To protect heavy-duty diesel engines, new Phillips 66-branded CI-4 oils are formulated to combat corrosion- and soot-caused engine and valve train wear, reduce piston deposits and bearing corrosion, and increase seal life.
