Shell Lubricants recently launched a new product—Shell Rotella T motor oil with Triple Protection technology. The company says the new and improved formulation is designed to meet the new API CJ-4 service category for heavy-duty diesel engine oils.

It provides significantly lower wear, “exceptional” deposit control and engine cleanliness for pre-2007 truck engines as well as the new 2007 emissions-compliant models, Shell said.

Shell Rotella T with Triple Protection technology was designed to optimize the durability and performance of DPFs (diesel particulate filters), the company explains, and overall, the lower ash content in the oil will mean the DPF will potentially need to be cleaned less often, which can lead to lower maintenance costs. Another benefit is in maintaining good fuel economy.

The new motor oil is also said to provide on average 50% greater wear protection than the previous formulation. These laboratory-based findings, according to the manufacturer, are backed by the results of over 5.5-million miles of on-highway road testing using current generation engines in which significantly lower iron wear was found.
