HOUSTON, Tex. — Shell Lubricants has introduced its Rotella T engine oil with Triple Protection technology which the company claims offers improved wear, deposit control and reduced emissions.

The new oil meets API CJ-4 standards so it can be used in 2007 engines as well as older trucks.

“Shell Rotella T with Triple Protection technology meets or exceeds API CJ-4 specifications in part due to an exclusive detergent system designed for outstanding control of piston deposits in 2007 engines,” announced Dan Arcy, technical marketing manager for Shell Lubricants. “We also expect that owner/operators and fleet maintenance technicians will be able to visibly notice the outstanding wear protection for valve train components.”

Shell has conducted engine wear tests which show Rotella T with Triple Protection provides an average of a 50% improvement in wear protection, the company says. The tests have been backed up by more than 5.5 million miles of on-highway road testing.

“We were very pleased with the way the new Shell Rotella T with Triple Protection technology performed in key industry tests, such as the Cummins ISM tests where it scored maximum merits for wear protection,” Arcy said. “For example, in the Cummins ISM engine test, valve adjuster screws showed less wear and scratching.”

The new oil is formulated with 30% more active ashless chemistry, the company says, providing added protection against deposits and sludge. It also boasts a new detergent system which provides better control of high temperature piston deposits.

Shell officials say the new oil will optimize the durability of diesel particulate filters, which will be found on 2007 trucks. The lower ash content of the oil will allow the DPF to run longer between cleanings, lowering maintenance costs, the company says.

Shell Rotella T with Triple Protection is already available in bulk and drums and will be on store shelves in quart, gallon and pail packages beginning Oct. 15.
