Shell introduces new synthetic CJ-4 HDEO

Truck News

HOUSTON, Texas — Shell Lubricants has introduced a new synthetic heavy-duty motor oil which meets API CJ-4 specifications.

Shell Rotella T Synthetic 5W-40 oil offers improved engine protection and increased fuel efficiency, the company claims. It also boasts significant improvements in wear protection, soot control, deposit control, heat resistance and it works better in extreme weather, Shell says.

“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.”

Shell says its new synthetic oil offers 36% better soot control than conventional motor oils. It’s designed for use with diesel particulate filters and EPA07 engines. Shell says the new formulation can extend DPF cleaning intervals. It’s also compatible with engines built prior to 2007.

Shell also claims its new synthetic HDEO can improve fuel mileage by up to 1% compared to conventional 15W-40 products, thanks to decreased friction and by reducing the energy used to pump the oil through the engine. That can result in fuel savings of $532 per year for a typical truck, Shell says.

“As diesel fuel prices continue to increase, the ability to offer potential fuel savings and increased engine protection may make spending a little more to buy a synthetic motor oil worthwhile,” said Silveira.
