PETROFLO 15W-40 SYNTHETIC HEAVY DUTY DIESEL ENGINE OIL, is a premium quality, high performance, fleet engine oil designed for use in on-highway diesel trucks and off-highway diesel equipment, as well as in passenger cars and light trucks with either diesel or gasoline engines. It is recommended for use both in EGR-equipped diesel engines and in older, non-EGR diesel engines. It also will provide excellent protection for gasoline engines for use in mixed commercial fleets. PETROFLO 15W-40 SYNTHETIC HEAVY DUTY DIESEL ENGINE OIL, is formulated with advanced additive technology to provide outstanding wear protection and bearing corrosion protection. High dispersancy-detergency and a high alkaline reserve (TBN) provide extra protection in extended drain or severe service intervals, and in EGR-equipped engines. APPLICATIONS: On-highway diesel trucks equipped with cooled-EGR, ACERT or other technologies to meet earlier exhaust emission standards. Older diesel equipment with conventional, non-EGR engines. Mixed fleets with both diesel and gasoline-fueled vehicles. Off-highway construction, earth moving and mining equipment. Farm equipment with diesel or gasoline engines.
