Do SCR systems require more maintenance?
The SCR system is self contained and requires very little additional maintenance. In fact in most cases service is restricted to one additional filter change (urea filter) annually, which is carried out during routine engine service. Due to the extremely efficient and clean burning combustion characteristics of an SCR equipped engine, oil service routines are simplified in many cases. The SCR technology ensures soot formation is reduced during the engines operation, thus reducing the need for frequent engine oil drain intervals and additional oil filtration systems. SCR engines require no specialised engine oils. The recommended grade of oil used in these engines is our MF Premium Engine Oil, which is a 15W40 grade with a classification of API CI-4 and is the current specification for most heavy duty diesel engines.
