Shell Lubricants introduced two new engine oils to its lineup that meet, respectively, the CK-4 and FA-4 performance categories, which became industry standards Dec. 1, 2016.

The new Rotella T6 Multi-Vehicle 5W-30 synthetic oil meets the CK-4 specification, and is formulated to be used in either diesel-powered Classes 6-8 trucks or in vans and pickup trucks running on gasoline, according to the Houston-based company.

“The full-synthetic oil has been engineered to provide protection under the most severe engine conditions for both diesel and gasoline engines,” Megan Pino, Shell Rotella global brand manager, said in a statement.

CK-4 oils replaced the earlier CJ-4 oils and are completely backwards compatible with all engines built before the 2017 model year, according to Shell.

In addition, the company launched a Rotella T5 Ultra 10W-30 synthetic blend that meets the FA-4 standard for 2017 and later diesel engines.

“It is designed to provide protection that adapts to driving conditions and is formulated to minimize oil consumption and protect exhaust catalysts and particulate filters,” Pino said.

Also on tap is a full-synthetic FA-4 oil that Shell will launch when the need for it in the market arises, according to the company.

Shell Lubricants is a unit of Royal Dutch Shell.
