A. Engines produced after 2007 are equipped with diesel particulate filters that require the use of CJ-4 oils. CJ-4 oils have been formulated to provide optimum compatibility and durability for DPFs. Using CI-4 Plus oils can shorten the service life of the diesel particulate filter, leading to higher maintenance costs or even replacement of the DPF.
