not sure if this has been said before but supermarket diesel is crap , it is called emulsion in the trade , it clogges up pumps and injectors ,its ok on old models but not on the newer commonrail models , if you want your pumps and injectors to last ,then stick to texaco,shell,bp and the other major supliers , if your car/van develops a fuel fault the first thing the dealers ask now is where you get your diesel , it is not worth the few pence a litre saving ,cause a pump and injectors will set you back £1000+

If I was a passenger in a car travelling 400 miles @ 60mph I would give you £20 just to put your foot down before I killed myself with boredom.

.... but if the driver was Angelina Joli you'd give her £20 to slow down .....

the million + miles ive done since 2003 ,with varios diesel vans and various pumps and injectors and took the time to read manufactures recomendations regaurding diesel engines , hence in that million + miles ,i never had to replace a faulty injector and only 1 diesel pump and that was caused by a leak rather than a fault ,which i might add is caused by the seals perishing caused by the lack of sulpher in modern diesel , sulpher acts as a lubricant for pumps

go and ask the manufactuers about supermarket diesel and what it does to your fuel system , its cheap cause its crap, another point is ford recomend diesel with less than 6% bio mix for the cars/vans ,yet all forcourt normal diesel has 7% or more bio mix

Well they are paid to recommend the fuel supplier they are partnered with so hardly an unbiased opinion.

Supermarket petrol is better than the big brands. My proof? Go ask the supermarkets.

Get my point. Baseless AND meaningless.

All fuel sold in the EU is made to set specifications and is set by them.

It is audited and verified as such. i will dig out the link if I can find it.

Where do you think the supermarkets get their fuel from.

The brands may add "extras" of greater or lesser benefit but the underlying fuel is the same. All the engines are built to tolerate the said fuels at he minimum specification. I did hear a rumour that the tanker driver simply adds this "extra" to the tanker enroute - that is probably a myth.

I appreciate there are some "vintage" cars that need leaded or 5* equivalent.

Do you really think the supermarkets would sell fuel that they knew to be duff?

I use all types of fuel and it makes not a jot of difference to my fuel consumption relative to the type of driving. That has been over a million plus miles.

As for diesel v. petrol in and out of town. Older diesels were better overall and certainly in town. Petrol used to catch up on the longer journeys. With high pressure diesel and turbos the diesel fluctuates a lot more but it in my experience it still wins.

, the supermarket fuel is not duff its just crap , it has a high water content ,hence the trade term emulsion ,it is blocking up fuel systems on modern cars/vans , ford recomend bp diesel ,not the brand i use ,my proof is the model vehicle i use has a high pump and injector faliuer rate and yet mine and others who dont use supermarket diesel seem to get millions of miles trouble free from them , maybe we just got lucky with our vehicles or maybe what im saying is right , im just offering my advice based on actual miles done and fuels used ,

Your model has a high injector failure rate, your's hasn't failed. That doesn't mean every injector ever made for it will fail. Doesn't mean your's won't fail at any moment. And doesn't mean there's any correlation whatsoever between that and your fuel. There's way too many variables that could be involved in that even if your injectors lasted 100 years. Speculation and opinion does not make something fact.

ford recomend bp diesel

Because they have a joint advertising agreement, nothing to do with fuel quality.

Agree this is the same as Citroen and Total.

Their must be some water in most diesel as the fuel filter on cars I have had have had a bleed plug on them to remove it:think::think:

Interestingly I notice that ASDA are selling fully synthetic oil 5/30 up to the latest spec apparently for £20.
