All service intervals are the maximum recommended period; always mind the service monitor system and perform maintenance as prompted. The significant differences in service intervals between 2007 to 2012 model year engines and 2013+ model year engines are do in part to the introduction of the SCR system and diesel exhaust fluid (DEF), which reduces the duty cycle of the DPF regeneration system and thus the rate of fuel dilution.
