(2 pack) (2 pack) Shell Rotella T4 Triple Protection 15W-40 Diesel Engine Oil, 2.5 gal.

Formerly known as Shell Rotella T Triple Protection, Shell Rotella T4 Triple Protection Heavy Duty Diesel Engine Oil is the most technically advanced Shell Rotella formulation ever. This 15W-40 motor oil uses advanced additive technology to protect under the most severe engine conditions found in modern, low-emission engines and older hard-working diesel engines. It effectively sustains emissions control system durability where diesel particulate filters and after-treatment systems are used. Plus, it provides enhanced protection against viscosity loss due to shear and improved oil aeration compared to the previous formulation.

Triple Protection from wear, deposits and oil breakdown, this conventional Diesel Engine Oil provides exceptional wear protection for heavy duty engines for longer life* Formulated with advanced additive technology, which is engineered for superior engine cleanliness throughout the oil drain interval Provides increased shear stability for better viscosity control and optimal engine oil pressure Heightens emission control system durability and improves oil aeration Provides enhanced protection against oil oxidation for more efficient operation *Shell Rotella T4 demonstrates strong wear protection in CK-4 engine tests including the Cummins ISM and ISB.
