Fuel Filter and refusal to honor warranty!

Gloomendoom

The reason that it only affects newer diesels is no mystery. The filters on common rail diesels are ten times finer.

There is a growing school of thought that the problem is caused by the biodiesel added to the mix. This affects all fuel outlets supplied from a particular distribution centre, no matter what brand.

Retired my Mondeo TDCi at 271,000 miles last year. Some injector wear diagnosed, one or two new ones were needed and the suspension was shot. The car had been worked Private Hire from 50,000 miles so that's not Motorway miles. Most of the work was urban driving over speed bumps etc.
I ran it mostly on Tesco's diesel or Asda with an occasional dose of Millers diesel additive. Fuel filter changed as per service schedule. I never had a moment's fuel trouble.

It does not seen to effect earlier diesels.

That's the whole point, it doesn't affect older diesels, my 7 year old Nissan isn't affected yet a relatives 2 year Qashqai is !!

Yes but some people just read between the lines.

It is a problem for newer diesels without a doubt and it does seem to be something to do with the amount of bio additives.

Its all down to this(and european) governments green targets, the manufacturers and dealers know that but what can they do

Hi there, just joined this forum. I am looking for advice regarding fuel contamination.
I filled my 59 reg car up with £60 worth of diesel at Sainsburys Team Valley petrol station today. When I took the fuel nozzle out I noticed it was frothy.
While driving home on the A1 my car started to judder as if it was in too high a gear. I made it home.
I have researched the internet and feel the diesel may be contamined. I rang the petrol station to ask them about possible fuel contamination and was advised to take my car to a garage to check for this. I have rang 3 garages and they do not check diesel for contamination. Where can I get the diesel tested?
Any help would be appreciated.

My Dad had same problem from sainsburys team valley on the 11th and he has found 2 other people who have also. He is trying to make a case against them, and has had it confirmed that the diesel was contaminated. I have sent you a private message, if you could get back in touch?

I understood the situation was that all the base fuels were more or less the same, but that each customer (Asda, Tesco, Shell, whatever) specified their own additive package, and that this was what made the difference between the cheap and premium brands. So your Esso will have detergents, anti-waxing compounds and so on that the Asda fuel doesn't have.

Is this correct, or not?

Yes it is. Additives are added to the premium brands (Shell BP etc)
but not to the cheaper brands.

Why anyone would pay for an expensive car such and then put in cheap supermarket fuel is beyond me...

Depends where your nearest Shell/BP/Esso garage is, mine are about 20 miles away so supermarket fuel for me, adding app £7 for every fill up is not my idea of saving money.

There threads always go the same way.

"Experts" say that all diesel is the same, but like DNA the last 1% is highly significant.

Supermarkets don't use the same additive packages as the bigger names, it really is simply as that.

A bit like Tesco milk and Cravendale, there is no doubt they both come from a cow, but why does Cravendale taste better?

Because supermarket products are made to be as profitable as possible whilst still adhering to the minimum quality needed to stay legal.

I used a 2011 Galaxy for six months around the Olympics, it would regen once or twice a day when Esso or Shell diesel was used, I did put Tesco in it one week due to needing fuel in an area I didn't know and could only find a Tesco.

On that tank it started to regen three or four times as often within a few miles.

When I refilled the next week with my usual Esso it went quickly back to the once or twice a day.

My wife uses Tesco all the time and her injectors sound like a bunch or maracas under the bonnet.

There is to much anecdotal evidence to support the fact that Supermarket fuel is at the bottom end of the food chain.

Use it if you like, but please don't spread opinion as fact due to the fact it might all come from the ground and the basic product is refined in the same place.

I have read comment on this from the Engineers working in this industry and they all say the same thing, stick to the big name brands if you want the best additive package in your fuel.

Though if you really want to use Supermarket diesel at least add some additives of your own, Millers, Redex or Wynns all do stuff to suit.

But water contamination is also a concern, especially if the driver of the car doesn't have the ability to empty the water trap.

Too much water in the filter on a Pug used to result in a big orange water light, not many manufacturers fitted these, but it is a sensible assumption that Pug would now make he car to into limp mode or similar rather than the orange light of yesteryear.

Water is bad news for a diesel engine.

So if they're meeting the legal requirement what exactly is the problem?
EN 590 is a Europe wide standard that has been in force since 1993, if supermarket diesel fuel meets this standard but "some" engines have problems & need extra additives to run properly then shouldn't we be looking at the engine manufacturers & asking why they are designing engines that don't operate correctly on the standard grade fuel?

Spot on but some posters insist it is the drivers fault for using cheap fuel forgetting the above
