Branded v Supermarket ' Standard ' Diesel and DPF compatible Additives

The biggest killer of the DPF rather then fuel is people lack of knowledge,

Some many people have been convince of you want high mpg get diesels, and when dpfs came comman place people lack of knowledge on how they need to look after lead to horror storys of blockages.

In my time in the trade its mainly misusing of the DPF that wrecks them.

But remeber its a filter and a service item that at some point needs changing, now on sprinters vans they tend to last 120,000 ish iirc.
