Shell Lubricants showed off its new “portfolio” of Shell Rotella CK-4 and FA-4 oils diesel engine oils, designed to meet Proposed Category 11 (PC-11) specifications finalized back in February, at a special media event in Washington D.C. Shell’s Rotella T4 Triple Protection 15W-40 and 10W-30, along with T5 Synthetic Blend 10W-30, meet the new CK-4 service category and will become available in August – though they will not be “licensed” as such until Dec. 1 – while Rotella oils meeting the FA-4 spec will arrive later this year.
