Shell Rotella T4 Triple Protection 15W-40 Diesel Motor Oil comes in a convenient 5-gallon pail, designed to offer top-quality performance for heavy-duty engines. This diesel engine oil delivers outstanding wear protection, ensuring longer engine life for a variety of applications, including diesel pickup trucks, tractors, and tractor-trailers. With advanced additive technology, it maintains engine cleanliness throughout the oil drain interval, even under the harshest conditions often found in modern low-emission diesel engines and older, hardworking engines.

The formula helps control deposits, which keeps engines clean and enhances overall performance and longevity. It also supports the durability of emissions control systems, including diesel particulate filters and after-treatment systems. Furthermore, Shell Rotella T4 offers improved resistance to viscosity loss due to shear, enhancing oil aeration compared to prior formulations. This makes it an ideal choice for various sectors such as on-highway fleets, construction, agriculture, public transport, and diesel pickup trucks, especially those that require increased heat and stress resistance.
