Top Dog for heavy duty diesels
Today’s heavy duty diesel engines are expensive, more technically advanced than ever before, with ever-increasing oil drain intervals. A customers fleet is often the backbone of their business, with reliability and component life meaning everything. Gulf Western Top Dog Indestructible has been formulated using Gulf Western’s indestructible additive technology, which the company says makes engines stay cleaner, use less fuel, and last longer. Top Dog Indestructible15W- 40 meets the majority of modern engine manufacturers’ specifications. It is formulated to meet API CK- 4, which is the latest heavy duty diesel engine oil classification released in January 2017 by the American Petroleum Institute. It meets the specifications of modern and older engine manufacturers and OEMs, and is backward compatible with API CJ- 4 and CI- 4 engine oil specifications. It is suitable for heavy duty diesel engines fit ted with EGR ( exhaust gas recirculation) systems and those fit ted with DPFs ( Diesel Particulate Filters). Being backward compatible with API specifications, it is an ideal mixed fleet / universal engine oil.
• Increased fuel economy
through reduced friction. • Extended drain intervals compared to earlier generation API grades. • Vastly improved oxidation
control. • Suitable for EGR (exhaust gas
recirculation) engines. • Low SAPS formulation offering suitability for diesel particulate filters. • Better dispersancy compared
to conventional API CK- 4 and CJ- 4 specifications resulting in cleaner engines that offer increased service life. • Increased shear stability resulting in decreased oil consumption. • As illustrated in chart 1, Top
Dog Indestructible15W- 40. • Offers advanced levels of engine protection compared to API CJ- 4 and even the new conventional API CK- 4 specification.
Chart 2 illustrates the improved engine wear Top Dog Indestructible15W-40 offers on a 150 hour and 200 hour ISM engine test compared to specifications API CJ-4 and even the new conventional API CK-4 chemistry. Top Dog Indestructible15W-40 performance...
Engine Test Data shown in Chart 3 verifies Top Dog Indestructible 15W-40 has 52 percent less wear than conventional API CK-4 and 59 percentless wear than API CJ-4 at 150 hours during the severe service ISM Engine Test. Top Dog Indestructible15W-40...
