Shell ROTELLA T Multigrade SAE 15W-40 with Advanced Soot Control is Shell's highest quality mixed-fleet heavy-duty engine oil. It meets the warranty and service requirements of virtually all diesel and gasoline engine manufacturers that recommend a multigrade oil. Recommended especially for all on-highway service applications, it may also be recommended for off-highway applications, especially where all-season use is desired. ROTELLA T Multigrade exceeds the requirements of both cleaner-burning new engines and earlier models. Shell's unique chemistry helps ensure that the oil stays in grade in all seasons and under all types of loads.
