You can use any C? rated that is D or later in the alphabet. CI-4 is just fine. The new CJ-4 is low sulpher oil for use in engines that have Exhaust Catylists, Particulate fiters, and or Exhaust Fluid injectors. Tier4 or Interim Tier4 engines. CJ-4 can be used on place of earlier rated oils as well. (CD, CE, etc.)
