Shell Lubricants Announces Shell Rotella Portfolio

Shell Lubricants 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. They are the most technologically advanced Shell Rotella engine oils ever and also offer the protection required by diesel engine manufacturers. 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, 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.”

Oil technology and engine technology go hand in hand. Changing regulatory limits challenge engine manufacturers to reduce emissions. As engine manufacturers create a new generation of lower CO2, more fuel-efficient diesel engines, they need a new generation of higher-performing diesel engine oils to protect them.

The new API CK-4 and FA-4 categories are driven by changes in engine technology to meet emissions, renewable fuel and fuel economy standards for reduced CO2 and other greenhouse gas emissions. In addition, the new specification refreshes test limits in response to changes in engine hardware and operating condition. The last heavy-duty engine oil category, CJ-4, was introduced in 2006 and since that time, several engine tests need upgrading and older test hardware has become unavailable.

  • CK-4 oils will replace today’s lubricants and will be completely backwards compatible with all current engines. They will be designed with improved oxidation resistance, shear stability and aeration control.
  • FA-4 oils include lower viscosity grades designed for next-generation diesel engines to help maximize fuel economy without sacrificing engine protection. These oils will have limited backwards compatibility because some older engines were not designed to operate with lower viscosity grades.
