I've used it for 2 years & 11,000 miles in my Blue HDi 100 & nothing has blown up/fallen off.To clarify,from new.

Ive know a good dose of millers to clean out a dpf so its more than fine to use it johny

It depends on the ash content.  It doesn't contain any ash, ash content is a measure of how much of it is left after it's been burnt.  For the same reason, engines that have a DPF use low ash oil, because a small amount of oil gets burnt so anything left after burning it ends up in the DPF.  There is no way out for ash particles in the DPF, so they build up and eventually block it - after which you need to buy a new one or have it cleaned at lots of expense.  The soot from diesel is almost entirely carbon, i.e. unburnt fuel, so when it does its regeneration the soot gets burnt and almost all of the particles blocking it turn into gases that can exit through the filter.  But anything that isn't capable of turning into gas gets left in and will eventually block it.

It would be perfectly possible to be gradually adding to the ash blockage in the DPF for thousands of miles and have no apparent problem at present - you would only be aware of it when the DPF needs replacing as it's full and a regeneration isn't clearing it.

So the answer isn't a Yes or a No, but to check whether it's intended for use with a DPF and/or whether it's rated as Low Ash.  There isn't a way of checking this other than checking labels, specs or asking the manufacturer.  It's possible that it's absolutely fine, or you may need to pay extra for a special version of it.  Low ash oil is always quite a lot more expensive, so the same may apply here.

Cheers for that,I know millers was OK for my old Berlngo no dpf,,wasn't sure about the new Berlingo with dpf,I thought will it clog the dpf sooner, or will it be OK,?,

Possibly because fellow owners can give you their personal experiences. Very valuable real life info.

But the only 'official' answer has to come from the manufacturer - in this case either Millers or Citroen. Hence Doofer's comment. Makes sense to me.

Gravity.,that's why I was asking on the forum to see if any one had personal experience on millers with a dpf
