Supermarket fuel

why does the wax not melt in the filter when the engine is hot and close proximity, surely the filter must get warm?

Not only that, I'd hazard a guess that a good proportion of the vehicles affected have a fuel heater on the filter mount.

If the fuel in the filter is waxed then the engine doesn't run as the wax obstructs the flow. Some vehicles have heated filters which prevents waxing in the first place but these are usually for colder climates than ours (Volvo is one that comes to mind).

Tankers fill up from the same part of the refinery, but then add a different additive mix depending on who the end customer is.

Cheap supermarket fuel is not the same as fuel from Shell and BP. You get what you pay for.

Can some tanker driver or others who KNOW please corroborate the above?

There was something on TV last week which stated that Tesco fuel has no additives, but I cannot remember which programme it was. I remember thinking at the time "That shows those people who say all petrol is the same are incorrect!"

I've never quoted myself before, but watching the BBC News just now has prompted me to where I heard the above. It was on a news report about the Phillpot trial where they reported that a forensic scientist stated they analysed some petrol as Tesco brand because it had no additives.

Seen a couple of threads about the 'just add fuel' promotion by Peugeot where the cars have had problems. According to the dealerships, if the owners use supermarket fuel, it invalidates the warranty!! Bet they don't tell you that when you have a look at one before buying it!

On what grounds?

All diesel fuel sold for road use in the UK should conform to BS EN 590 so are Peugeot saying that supermarkets are supplying inferior/non BS standard fuel? If so then Trading Standards would be interested.

While I concede the obvious superior knowledge of some of you with regard to engines, I find that most of the claims relating to this subject are based on opinion and the flimsiest of evidence.
Most of it is anecdotal, and often 2nd and 3rd hand. I found it particularly unhelpful, that while anecdotal evidence supporting the claim that Supermarket fuel is inferior is accepted, my own personal anecdotal experience of having no fuel related problems over a very large mileage for many years is relegated to that of having as much relevance as “The price of Eggs” and having no relevance whatsoever to the debate.
I have written to several Supermarkets, Tesco’s, Sainsbury’s, Morrison’s, Car manufacturers, Peugeot, Mercedes, , and to BP, Shell, Esso and my Peugeot Dealership.
I also spoke to a Tesco tanker driver who was making a delivery to my local branch. He said that yes, there were differences in the additive package for Petrol, but that it was exactly the same for Diesel when he delivered to Supermarkets or Branded fuel stations.
I have copied their replies below
Please note that Morrison’s specifically state that their fuel conforms to EN950, as do all of the supermarkets, exactly what is required by Mercedes.
None of the fuel companies have replied, I wonder why not, possibly because they cannot and do not wish to claim that their branded fuel outlets although more expensive are exactly the same fuel as the supermarket.
Quite frankly, it is an insult to common sense to suggest that the millions of Litres of fuel sold to millions of users are causing damage to engines. The claim made that Mercedes specifically recommend premium fuel, is not quite correct, they recommend EN950 fuel for their Diesel engines that does not imply that it cannot be supplied from a Supermarket and it does not mean they are against the use of Supermarket fuel as is clear from their reply.

Mercedes-Benz

Thank you for contacting the Mercedes-Benz Customer Assistance Center Maastricht N.V.

In response to your email communication of 15th March 2012, we wish to advise you of the following information regarding fuel.

In the case of a petrol engine, EN 288 specification petrol must be used with at least 95 RON, if this fuel cannot be found 91 RON may be used as temporary measure. In the case of a diesel engine, EN 590 specification diesel fuel can also be used as well as E10 fuel. This information can also be found in the back of Mercedes-Benz Owners Manuals.

Thank you for your email regarding fuel.
I have spoken to my Business Support Team regarding your query.
They have advised me that, there are minor differences between additives in fuel sold by the different UK retailers. However, I can assure you that it is not correct that Tesco fuel contains inferior additives. In most cases, it will be the same type and dosage of additive that is contained in fuel sold at branded filling stations. I cannot, however, confirm that this would be the same for other supermarket fuels.

I can also confirm that Tesco diesel fuel does not contain less cold flow improver additive in winter compared to branded diesel. Often it will be the same measure and type of additive contained in diesel fuel sold at branded filling stations.

Finally, I would like to reassure you that Tesco has an industry leading and comprehensive programme of quality control testing on all fuel sold at its filling stations.

Wm Morrisons Supermarkets PLC- Ref 154663Thank you for your email.
In regards to the quality of fuel sold at Morrisons I would like to offer the following comments, Morrisons unleaded and diesel is supplied to us by nearly every one of the refiners and blenders that operate in the UK.
We source locally from established and reputable refiners and blenders
Our fuels are manufactured and guaranteed to British Standard EN228 and EN590, precisely the specifications that will be found in all vehicle manuals. These current specifications permit upto 5% renewable content in petrol, ethanol, and upto 7% renewable
Content in diesel, Fatty Acid Methyl Esters (vegetable oil).
European law requires all road fuels to contain such renewable feed stocks.
Currently Morrisons sells 10% of all motor fuels sold in the UK to motorists, fleet operators, hauliers, local authorities and to our own staff.
Also in relation to the winter fuel I can advise that Cold flow additives in our Diesel guarantee the properties of Diesel down to minus 15 degrees centigrade.

Our Diesel conforms to the required specification.

We are legally obliged by law to have the additives in our diesel from the end of October up until March/April.

I haven’t heard anything officially negative to modern UK supermarket fuel but I have heard things suggesting its worth avoiding the supermarket fuel abroad
Will see if Peugeot have a stance

Paul has just said that there are winter additives in non supermarket diesel which prevent a new version of the old problem of the diesel freezing up. Basically because the latest diesel engines require a finer filter, this can block with the small crystals formed when the temperature drops. Apparently not all supermarkets sell this ‘winter version’ of diesel. There are apparently other additives which supermarket diesels not have but I have never experienced any noticeable difference. Peugeot do not have a published opinion on fuels other than informing us they wont pay for any work on frozen fuel affected cars, which Paul says actually wont harm them.. just might cause the car to not start or go into ‘limp home mode’

He is a Peugeot Dealership Retail Sales Director ?

Please say you have this in writing, if so Paul has just landed Peugeot in the brown stuff as he has just said that these engines cannot be relied on to run with normal diesel fuel, or in other words they are not fit for purpose.
