DPF cleaner fuel additive

AdrianC

My mother runs a 6yo Pug 207HDi. She's had it from new - and it still has less than 40k miles on it, mostly short local runs.

Yep, prime candidate for DPF problems... It's already had the DPF cleaned out once...

So, when it went bing and popped up "Antipollution Fault", then refused to move any further, whilst I was with her the other day, the cause seemed fairly obvious. I was wrong - it turned out to be a low fuel rail pressure fault code. Green Flag cleared that, and it's been absolutely fine since. But the guy did strongly recommend a DPF cleaner fuel additive.

My natural scepticism is screaming "Cold-pressed extra-virgin python". But I said I'd look into it, and a tenner every few months is not expensive insurance, if they work.

So - what think you? Any brands more or less effective than others?

I have wondered the same for a while. Any of the diesel additive that actually offer a real benefit and any that do something to the dpf?

You're probably better off taking it for a quick blast up the motorway every couple of weeks or so.

Her nearest motorway or substantial dual carriageway is an hour each way.

Rent the car out for a few hours every month? It will certainly be returned with a "very" clean dpf.

Who advised her to buy a diesel ?

In practice PSA cars with the EOLYS additive system suffer little in the way of blockage problems compared to other makes, is the fluid system working correctly.

I no longer run Diesels, DPF a complication too far for me, but i always ran Millers Diesel Power Sport, or whatever its now called, in the fuel, never had a problem (but then thousands who didn't use it never had problems either), might be worth a shot, it seems to be a cheaper way to run the better Diesel on offer at some stations.

I think reputable named brands such as Forte or Millers products might be worth a punt, not sure about some other brands aimed at the road racer types.

Definitely not me, that's for sure... Her previous car was written off, and she bought the first small estate she could find immediately available...

I drive a diesel, but drive a 40mi motorway commute each way.

For short, occasional runs, I'd never recommend a diesel.

My car occasionally has the 'super' fuel in it, but whether it would work in this case is debatable.

No, nor would I. But it's what she's got, and she's not planning on changing it any time soon. So...

The cheapest thing to do first, is to try it with a tank of 'super' fuel (or even just £10 worth on an empty-ish tank), then run it up/down a motorway for half hour.

To the red line in 2nd and 3rd on the onslip, then drive normally (to disperse soot and replenish the DPF).

I do this about once a week in mine, and after 19 months/98000mi, the unit was changed for the first time about 2 months ago, with no intermittent problems.
