Not just on this forum Graham, take a look at the Fabia, Roomster, Octavia, Superb and General Chat forums let alone the hundreds of other motoring forums (Honest John & Piston Heads to name a few).

The topic has been done to death and I've read a lot of them, including posts from tuning companies, oil refinery workers, petrol station employees, fuel tanker drivers, you name it they've all contributed.

Despite this I've yet to see any proof other than peoples opinions, rumours and what the bloke round the corner said.

I've tried branded fuel and supermarket fuel for long periods and never noticed a jot of difference in either performance, MPG, DPF regens or engine reliability.

I work in marketing for a large well known company; if branded fuel was indeed better than supermarket fuel they'd be shouting it from the roof tops.

Until I see hard evidence (not just hearsay on forums) then as far as I am concerned supermarket fuel is as every bit the same as branded fuel in all but price.

So should we all sell our diesels and get petrol motors then??

DPF filters - : ADVICE FOR CUSTOMERS - Honestjohn

SMMT figures show that diesel cars are currently outselling petrol engined cars in the UK. Of course, the majority are going onto fleets and fleets and leasing companies will be relying on their residual calculations based on past experience. Fleet cars tend to do relatively high mileages and are less susceptible to DPF trouble. And the other problems with diesels such as DMF failure, turbo failure, blocked EGRs and needing a new timing belt don't tend to occur until years 3 - 6, after the fleets have disposed of the cars. It will take the GBP a while to cotton on to this. But as soon as TV shows like BBC Watchdog start putting the message across, firstly about the unsuitability of many diesels for short runs from cold, and secondly about the potential high repair costs in years 3 - 6, I can see the value of diesel cars coming off fleets plummeting by at least 20%.

this was honestjohn´s opinion in this thread

Rather concerning if you buy your own cars rather than get a new company one every few years...

Skoda UK do produce a leaflet on the DPF, which does include a warning of sorts that DPF equipped cars are not suitable for everyone and I quote;

"Is there anything else I should know about DPF?

• If the DPF needs replacing and the guidelines/recommendations made by Škoda have not

been followed, the cost of replacement will not be covered by the manufacturer’s warranty.

• Frequent short journeys or stop/start driving may not provide optimum conditions for the

regeneration procedure.

• Consider your driving style and length of journey to allow for the driving conditions required

for DPF regeneration, as described in this leaflet and in the owner’s handbook.

It is advised that you consider the important information outlined, before ordering a vehicle

with a DPF. For any further information please contact your authorised Å koda retailer or repairer."

Interesting to note I've only seen this leaflet clearly on display in one dealership and I've seen extracts of the leaflet published on some dealers web sites but funny old thing the above appears to be the bit omitted :wonder:

Consider my driving suitable for DPF; very few short journeys or stop start driving and my first Monster regenerated once in a blue moon but weekly or even thrice daily is a bit OTT.

My Dad was a Bulk Plant Manager for Esso, at 3 different depots.

I believe what he said, and have seen the proof.

Result is I NEVER buy supermarket fuel in the UK.

I asked the paperboy this afternoon, he reckoned his BMX ran better on supermarket fuel.

However he did say that his cousin's half sisters friend of a friend reckoned vegetable oil was the way forward.

I told him he should share his experience on an online forum for the benefit of others.

So are you saying my father was a liar? I find that very insulting.

No Graham, I'm saying I don't believe you or your father.

For every unsubstantiated claim of which fuel is better there is another claiming the exact opposite.

I don't know the real answer and I suspect nor do you.

As for the effect on the DPF of different fuels then again we can all share our own personal experiences but that's all they are; personal experiences. There are as many members reporting DPF issues running on branded fuel as there are running on supermarket fuel, this is why I have no real preference as to which pump my fuel is dispensed from.

If you want to twist this into a insult then feel free, however if you want some real examples of insults let me go back and see if I can find some of your classics.

I will repeat exactly how my father described the loading of various retailers tankers when they arrived at his depot.

The tanker driver, who could be from any number of different retailers, logs into the loading system with his order number, as given to him by the loading operative.

That order number specifies what is going to be delivered to each of the tankers "receivers".

The "manufacturing" retailers (eg Shell, Esso, Texaco, BP) then received their loads of fuels PLUS several additional additives. These always were:

1/ a chemical trace and dye to prove duty had been paid,

2/ a chemical trace and dye to prove the end retailer,

3/ diesel anti-smoke agent

4/ diesel anti-foaming agent

5/ injector cleaners, petrol and diesel,

6/ diesel anti-waxing agent, normally between the end of October to the end of March.

The supermarkets would be loaded in exactly the same way, but they would only receive

1, 2, and 6, although Tesco did specify greatly reduced percentages of 3 and 5.

In all cases the basic fuel delivered was to the BS standard.

Certain retailers, especially the very small independents like Dragon, buy there fuel on the open Rotterdam market, and they often only contain 1 and 2, since that is all they have to by Law.

My Yeti came with a small leaflet attached to the key ring explaining how to get the best out of the DPF, I have to confess that I never read it as I had read up on the topic on this forum. If my commute was not as long I would definetly consider petrol over diesel, particulary as diesel prices are predicted to over take petrol prices. Interestingly Skoda Ireland recently posted this article on their website to promote the launch of the 1.4TSi Superb Green Tech over here.

Careful Silver1011. There are 2 secret rules on this forum -

1. Llanigraham is never wrong.

2. If 1 does not apply - your post gets censored and the thread is closed.

1/

If I am I will admit it, unlike others on here.

2/

I only report posts that are insulting, inflamatory, or should be in another section.

I'm no expert but Llanigraham's account explains an experience my father-in-law had with his RAV4 last winter. He was extolling the virtues of his local independant (Irish I think) retailer near Bicester - several pence cheaper than the major brands - and then his engine conked out on the motorway when the temperature was -14C! If some cheap independants sell diesel with no anti-waxing agent then that makes sense.

Off topic and pretty pathetic attitude imo. :wonder:

Perhaps we could get back on topic now....

The only way this could be resolved is if the British Standard specs made items 1 - 6 in Llanigrahams post compulsory but then we'd miss out on these amusing threads. Right i'm off to fill up at Morrisons now cos the girl on the checkout says the fuel is just the same as BP, Shell etc.
