Most likely yes because you did not say which engine and year your diesel is. So here is a list for you to double check that your cummins engine has one of these requirements:
API CJ-4, CI-4 PLUS, CI-4, CH-4, SM, SL, SH; ACEA E9; Caterpillar
ECF-3, ECF-2; Cummins CES 20081; DDC 93K218; Ford WSS
M2C171-E; JASO DH-2, MA; Mack EO-O Premium Plus; MB Approval
228.31; Volvo VDS-4
