Shell Rotella T5 10W-30 Synthetic Blend diesel engine oil with Triple Protection Plus technology combines synthetic base oils and advanced additive technology to provide protection against wear, deposits, and oil breakdown. Triple Protection Plus technology also provides better low temperature flow, and Shell Rotella T5 10W-30 delivers better cold cranking properties than conventional 15W-40 oils, reaching critical engine parts faster in colder temperatures to minimize wear in harsh climates. It also provides fuel economy savings up to 2%, compared to a conventional 15W-40, helping you stretch your budget and improve your bottom line. Shell Rotella T5 10W-30 Synthetic Blend is suitable for a wide range of heavy duty engine applications. It is an excellent choice for on-highway fleets, construction, agriculture, and diesel pick-up trucks, including high-power vehicles where resistance to increased heat and stress is required.
