Hi there
Switching to 50ppm diesel may shorten the distance your vehicle will go before needing to regenerate the DPF - in fact, this has been known to happen with some Gauteng-based Qashqais with that same engine. However, this only becomes an issue on vehicles which mostly travel short distances (short hops which don't allow the engine and DPF to reach full operating temperature). It's not a major issue, however - a steady-speed drive of about 30 km on the freeway is usually enough for the DPF to regenerate without lasting effects.
10ppm diesel has inherently lower lubricity than 50ppm diesel (the sulphur actually aids in lubrication of the fuel system), but to compensate, SASOL has developed a special additive pack for their 10ppm diesel. At the time when 10ppm diesel was announced, SASOL's representatives made great effort to inform us of this, so they're definitely aware of this potential pitfall - and have clearly made provision for the added lubrication needs brought about by using 10ppm diesel.
Hope this helps!
