I had known about this issue with diesels for some time and indeed, had heard that many thad thought it was scaremongering. It is not the quality of the oil that is in your car [although I use the oil recommended by Jaguar] but the quantity that is in your sump.
Preventative measures, and using good fuel are important, and those that do this will be rarely, if ever.troubled by the DPF full message .
It is important that you check the oil yourself -- not an exacting task -- rather than depend on what a mechanic tells you, unless you know and trust the mechanic.
I was told when an exhaust was bing fitted that my brake discs needed changing, and that car passed 3 MOTs after that without any change in discs.
