Shell Lubricants is now offering the Shell Rotella T Synthetic 5W-40 heavy-duty motor oil which meets or exceeds API CJ-4 specifications. The oil provides protection against soot, dirt and other contaminants that can cause engine wear and deposits, Shell said. It also resists breakdown by heat to supply severe operation protection.
“In seven out of seven standard engine tests that measure wear, compared to the previous formulation, Shell Rotella T Synthetic 5W-40 has demonstrated an average of 34% improvement in wear (ranging from 2% to 90%), with substantially improved protection against cylinder liner wear,” said Walt Silveira, North American technical manager for Shell Lubricants. “This is a significant benefit when a truck is used for low-speed operations, such as hauling heavy loads.”
The formulation is compatible with the exhaust aftertreatment devices such as diesel particulate filters (DPFs) found on heavy-duty trucks built beginning in January 2007. The low-ash formulation also helps control the rate of DPF blockage.
Shell Rotella T Synthetic 5W-40 meets or exceeds the API CJ-4 requirements for Cummins CES 20081; Caterpillar ECF-3, ECF-2; Detroit Diesel 93K218; Mack EO-O Premium Plus; Mercedes-Benz Approval 228.31; and Volvo VDS-4. It is also suitable for off-highway applications where 500 ppm diesel fuel is used. The high-TBN formulation gives added protection in off-highway or for extended oil drain intervals.
