Have you actually used a DPF engined vehicle and compared how often they Regen on the different fuels?

As if the additives missing from supermarket fuel were unimportant due to the relative small amounts present then surely Eloys fluid would not work and neither would AdBlue.

But that is a moot point since Eloys fluid and Adblue do work as does the better additive package in premium fuels.

I very rarely use supermarket fuel.unless the choice is use it or run out.

I have put hundreds of thousands of miles on diesels over the last 10years.

My wife uses supermarket fuel all the time.

Do you want to guess whose diesel ended up smoking like a dog with injectors sounding like a bag of spanners?

I have done hundreds of thousands of miles in diesels over past 10 years on nothing but supermarket diesel. never had any smoke or injectors sounding like a bag of spanners.

If a diesel doesnt work properly on supermarket fuel the problem is with the car/manufacturer and not the diesel

totally agree with this. have had a couple of people telling me this also,complete tripe.

the problem is not the fuel its the dpf's.if your driving habits do not match a modern diesel with dpf,walk away. OP change to a petrol model. a motorway run 'once or twice a month' is not sufficient

Wrong.

There is a difference between working and working as efficiently as possible.

An engine can adjust to poor quality fuel which is why it is fairly simply to remap them for more power and torque.

Simply because they are mapped from the factory to take into consideration different quality of fuel.

And that doesn't mean fuel in third world countries but also poor quality diesel fuel with the bare legal minimum spec to be legally sold.

If all diesel was indeed the same then why have Shell not been sued for charging extra for some diesel when as you suggest it is all the same, the same can be said of BP and Esso.

So why has there not been a case for fraud with these retailers selling identical diesel at two separate prices.

But then some people can't tell the difference between Tesco Beans and Heinz Beans......

Just because some people can't tell the difference doesn't mean there is a difference.

Your usage matches a DPF?

Most of my miles are round London.

Use decent fuel and they give less problems, it really is that simple.

How do you explain the hundreds of Met Police diesel Astras, i30s, 5 Series and 3 Series that never ever go on a motorway? And indeed the Volvo V40s, V70s and Octavias.

Met Police only use BP as do the Ambulance Service in London.

And all of their fleets have a DPFs fitted, even the 53plate and older 2.7 Sprinters as they had to be retro fitted for the LEZ about 4 yrs ago.

The Police and Ambulance fleet managers recognise that using decent fuel contributes to vehicle reliability.

Just like only using decent oil and filters etc.

I dont own a Diesel myself but a friend of mine has a work supplied Transit and fuel card. They've been told to avoid filling up their vans at supermarkets unless they have no other option or its an emergency by their fleet manager.

He was told that the fuel quality at supermarkets is hit and miss, most of the time being of a lower quality to what you'd find at a proper filling station due to not having sufficient additives whatever that means.

The local police and ambulance use the local Tescos for fuel as it's closest to where their vehicles are based. I guess they don't have a clue after all since no vehicle can run on supermarket fuel reliably...well apart from the millions of vehicles that have done for years and somehow escapes everyone's notice, well apart from your wife's car rather conveniently.

Nothing the OP has said suggests it's a problem with driving habits though, the car went in with a failed DPF sensor which will happen regardless of driving habits and the car lasted 12 months before the problem started happening - if the DPF was failing to regenerate due to the OP's driving habits it would likely have been back to the garage a lot sooner for a forced regen.

Good luck to the OP, hope they sort you out.

On the diesel/DPF issue, I have a 1.6 diesel C4 Grand Picasso which the wife uses for commuting during the week. 1.2 miles each way (I know, but there are reasons) and we use for the occasional run out at the weekends up to about 15-20 miles and even more occasional longer motorway run.

Fill up exclusively with supermarket fuel (Asda or Morrisons) and have never had a problem with DPF or even noticed a regeneration happening.

My dad had a Peugeot 508 (high spec sporty one) which he fuelled exclusively with BP, good mix of town and motorway driving, which he got rid of after the DPF went and the car was never the same again despite being "fixed".

Go figure :cool:

In Immimgham is fuel depot.
You can see hundreds of yards of every brand fuel trucks queuing to fill up.
In they go, out they come, there does not appear to be any separate lines for each companies fuel.

Just because you can't see it doesn't mean that different fuel mixes aren't being pumped out to the tankers.
