    Never heard of any and I am suspicious about additives and how much that do. Do you have a problem with it blocking or doing regens?

    Well it recomended by vauxhall to save a regen. I am going to buy some tommorow. And put in my z30 . I have done 3000K since march and it has not reg onnce yet. You don't have to reg it until the glow plug warning light flashes. But this stuff will stop this.

    If you have a DPF mate it WILL have regen'd in that milage. The glowplug light flashing was removed by a software update years ago because people kept thinking there was a problem with the car and not reading the handbook instead...

    All seems a bit queer to me... what is the product they recommend?

    Also, PPL who have bashed out their DPF on the 1.9s still having the car doing regens (despite there being little / no differential pressure) as the ECU does it at set mileages regardless. Not heard of similar 'treatment' of a V6 DPF and what it does if it does not see a rise in differential pressure...??????

    Maybe there is some confusion between different methods of DPF regenning - one is to throw a load of burning fuel down the exhaust and heat the DPF until the soot burns, the other is to add a fuel bourne catalyst that lowers the 'light-off' temp of the soot in the filter and it can burn naturally. Given that most cars operate at very partial throttle for most of the time (as opposed to commercial engines / marine engines / some genset applications), the exhaust gas temp is not high enough to initiate 'self regeneration', so "help" in needed via these methods.

    Would be interested to find out more about this if there's 'mileage' in it

    Its a german product called Tuneap for people with DPF cars that only run around town and do not to the revs to clear th dpf normaly. As for people saying that if you computer says it doing 1 mile per gallon on tickover tells you it doing a regen. Any diesel I have owned does that. How can the ABS system tell you are doing a regen beats me.

    How wrong can you be in one post......

    If you have a car that you only run around town you should have a non-turbo petrol in the first place and not a diesel.

    All diesels run at about 0.1 or 0.2 gallons per hour on tickover When my V6 was doing a regen, the engine noise was audibly different, the consumption at idle went to about 1.0 gallons per hour and about 25mpg on the motorway cruising at 70.

    What the **** are you on about the ABS system for...?

    You tell owner that not me. Loads of people buy diesel because of the MPG they get out of them. if you by a corsa 1.2 and run it around town it will only do 250 miles to tankfull . My dad has a 1.3 cdti runs around town and get 600 mile to a tankfull.

    I never had that at all if you run on a motorway at 2.500 rpm for 20mins the dpf will stay clean all day long. I went to southampton monday at 70 mph on M4 car was doing 48-54 MPG has never done any less. Both my V6CDTi 's Y30 and the Z30 do 450 miles to a tankfull running around Bristol an 600+ on long runs.
