It's ironic that just a few months ago didn't Tescos get some nomination for the cleanest petrol or something??
I heard about it on the radio yesterday and was wondering what the implications were on a TVR and how will we know when it's okay to use again? Feel very sorry for the people it has affected, hope they can claim from Tescos!

I've heard this before. Might not have to go there for my petrol in future.
Oops, seems like I might have things the wrong way round!
I've posted in the Cerby area but have given a more complete explanation in the TVR General area. Here is a copy of my post, hope it helps you...
Morrisons, Tescos, Asda, Jet, Murco and some Total use the same supplier. Read into that what you like, but I would definately not take any chances right now !!!!
Sainsbury's Fuel comes from BP so these two are ok. BP, Esso and Shell should be fine.
The problem seems to be in the south of the country.
When the findings of Trading Standards are published it should reflect the above.
IMHO the alcohol content of fuel normaly stays around 5%. This figure can be increaded by the fuel supplier, but should be declared at the pumps. It's possible maybe, that the alcohol content has been increased and this has lead to the Lambda sensors burning out because the fuel burns hotter.
If you have recent reciepts for fuel, guard them as you would a winning lottery ticket
PS I'm off today taking the Cerby out for a blast, it's got a tank full of Shell V-max to keep the Lambs smilling all day :-)

kent area reported it first about two weeks ago. It's taken the BBC until yesterday to pick up on the story when parts of London and Herts have started reporting the problem also.
Renault and Vauxhall dealers have reportedly run out of Lamda's - official parts anyway.
BBC News had a Renault mechanic from Herts on this morning saying he had 22 vehicles in his shop alone affected.

It says on the news that the Tanker that shipped the fuel over to the UK had not been cleaned of its previous contents (some chemical apparently), therefore the fuel that the tanker carried thereafter became contaminated. If this is unrefined then I suppose that both normal and super unleaded can be affected? If not then maybe it is just one or the other?
Another question I want answering is why would you never put Tesco 99 in your car when it has had so many good reviews? or do you just mean that you wouldn't put it in while the scare is on? I have Tesco 99 in mine at the moment (filled up in Chesterfield at the weekend) and have had no problems.
Jules.
I generally prefer Tesco fuel because of their large turnover. Fuel doesn't sit long in their tanks, so it ought to be "fresh". Octane degrades, although admittedly pretty slowly. More than that, I live in the belief that water ingress (one of the biggest concerns for slow turnover fuel tanks) should be lower with Tesco, again because of their high turnover.
I can't help feeling that this report is just another case of poor journalism. The facts have not been researched. An article has been drafted and published on the back of a genuinely greater-than-normal series of failures as well as a load of rumours as to the source of the problem. Cerby 4.2 hasn't helped by simply stating that as a tanker driver *he* wouldn't use Supermarket fuel without qualifying why.
A bad batch has got through to the supply chain. Supermarkets simply stating that they are not responsible because they carry out testing on each delivery have published such a statement simply as a first defence against the £5000 per incorrect delivery they would be forced to pay out. It is very likely that their source is responsible for the bad batch and that we've already seen the end of it. Panicking now won't help. Claiming you'll never use Supermarket fuel NOW won't help. The horse has left.
I'm off out to fill up the Cerb with Tesco's 97RON, however I won't notice any difference between the fuel I fill up with today or any other day because my Cerb doesn't use the standard Lambdas installed in the exhaust. They're switched off because this Cerb has been mapped properly, which means the AFR is too rich for the standard Lambdas to make any "in flight" corrections anyway.

Load of twaddle if you ask me.
Unless something pretty serious has got in the fuel it's very unlikely to "burn" out a Lambda sensor.
Increases in Ethanol will just cause the engine to run richer and feel down on power. They might be experiencing loss of performance do to rich running (caused by the oxygenated Ethanol) and coking of the plugs and Lambda sensors.
As an example, I've heard one garage say...
"We've saved you £100's as we managed to reprogram the Lambda Sensor""
Are you pulling my chanker? You can't reprogram a bloody Lambda Sensor!! :lol:
Something has got in to a delivery by the sounds of it but I suspect that the finding will highlight one or maybe a few stations affected by this tankers contaminated contents and the rest is just internet whispers and hear-say then getting to the national press who make a big soang and dance about it.
Or BP, Shell and the like or on some massive poo throwing mission.

Not sure. The most likely is that they've had one tanker full that's iffy. It seems they used tankers to carry all sorts of chemicals, don't just stick to transporting fuel. If one of these wasn't cleaned out?
Silicon has been found - nor from detailed test done from trading standards tomorrow. Seems they've got samples from the affected cars.
With the throughput through the refinaries/storage depots/petrol stations, it's no surprise they haven't found any contamination a week or more later. Plus with a possible repair bill/compensation running into lots of money they probably want to deny all knowledge.
Imagine Tesco's bad publicity - "Every little helps - to shag your engine" - not something they'd be keen to accept.
