Yes. A new, heavy-duty diesel engine oil category was introduced for 2007 and newer engines. The industry designation for this new category is called API CJ-4. Just as with the requirement for the use of ULSD, API CJ-4 engine oils are required to ensure durability and continued performance of the new emission control technologies. Shell offers truckers this new heavy-duty diesel engine oil specification under the Rotella T & Rimula brands.
