It is a good oil no doubt, but definitely not a low SAPS DPF safe choice IMO. The stealerships use any shit they feel like. From a little research I've done, it seems the non-DPF safe oils tend to do a better job protecting the engine thanks to all the additives that would contaminate DPF and catalytic emission systems. Generally, it is claimed that a DPF is good for around 120 000 k's using the correct oils and oils with a higher SAPS and additive content might cut that life in half. Then of course some vehicles implement the DPF clean strategy much better than others.
