Shell Lubricants has introduced a new portfolio of Shell Rotella heavy-duty diesel engine oils. New Shell Rotella T4 Triple Protection 15W-40 and 10W-30 along with Shell Rotella T5 Synthetic Blend 10W-30 are formulated to meet the specification criteria for the new API CK-4 service category for diesel engine oil. New Shell Rotella API FA-4 oils will be available later this year.

“We have been working on the new CK-4 and FA-4 specifications of heavy-duty engine oils for more than five years, keeping in mind that meeting the new specifications was simply a starting point for Shell Rotella,” said Chris Guerrero, Shell’s global heavy-duty diesel engine oil brand marketing manager. “Our real destination was to create our most technically advanced, hardest working products to date. These oils have been tested over millions of miles and thousands of hours on the road and in the field. They are proven to work just as hard as the folks who use them, in both newer and older equipment. And with our updated portfolio structure, choosing the right Rotella oil has never been easier.”

Shell Rotella T Triple Protection is now Shell Rotella T4 Triple Protection in the new Shell portfolio, and Shell Rotella T5 Synthetic Blend 10W-30 has been reengineered as well. Both of these engine oils will be on retail shelves soon.

Shell Rotella T5 Ultra [Synthetic Blend] 10W-30, which will meet the API FA-4 specification, will be introduced in December. It is designed for improved fuel economy versus Rotella CK-4 oils while offering equivalent wear protection to CK-4 products. Shell Rotella T5 Synthetic Blend 15W-40, Shell Rotella T6 Full Synthetic 5W-40 will also be reformulated to meet CK-4 specifications.

Shell Rotella T4 products will maintain their white bottle, Shell Rotella T5 Synthetic Blend products will maintain their silver color and Shell Rotella T6 Full Synthetic products will continue in blue bottles. The bottles retain their two-handled design and thin dimensions, and will be available in one-gallon and quart sizes.

Selecting the proper Shell Rotella engine oil for a truck or equipment will be easy, the company says. If it was built prior to 2016, whether it is on- or off-highway, choose CK-4 oil which directly replaces CJ-4 oils. For a 2017 on-highway vehicle; check with the manufacturer before changing the oil for the first time and if they allow a FA-4 oil, choose Shell Rotella T5 Ultra 10W-30. Shell Rotella will also be introducing a Shell Rotella T6 Multi-Vehicle 5W-30 which will meet API CK-4 and API SN standards allowing its use in both diesel and gasoline engines.
