Shell Rotella T5 Synthetic Blend 15W-40 Diesel Engine Oil (2.5 Gallon, Case of 2)

Synthetic blend 15W-40 diesel engine oil with Triple Protection Plus technology protects against wear, deposits, and oil breakdown. Ideal for on-highway fleets, construction, and agricultural machinery, and diesel pickup trucks — including high-power vehicles that require resistance to heat and stress. Improves low-temperature flow (compared to conventional 15W-40 oils). Helps control engine deposits for reliability at extended oil drain intervals (always follow the OEM recommended oil drain interval). Controls engine wear 37 percent better than the maximum wear requirements in API CK-4 engine wear tests. Improved oxidation performance for increased resistance to oil breakdown under high temperatures compared to the previous formulation. Case of two 2.5-gallon bottles
