A full synthetic oil, the new T6 Multi-Vehicle 5W-30 meets the API CK-4 specification for diesel engines and API SN specification for gasoline engines.
Rotella T6 Multi-Vehicle 5W-30 has been extensively evaluated, Shell Lubricants engineers note, and exhibits excellent performance across API CK-4 and OEM tests, plus outstanding wear, oxidation and deposit control for diesel engines.
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.
"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.
Premiering in December, API Service Categories CK-4
and FA-4 succeed Service Category CJ-4 oils that have been widely recommended among on- and off-highway diesel engine manufacturers over the past decade.
