Remember Tesco had a problem before with silicone getting into petrol before at a refinery.

I'd be blaming the onion selling surrender monkeys who built it before I'd start blaming Tesco's !!!

I think the salient thing here is that it's a turbo engine. The boost level is variable, and the higher octane fuel allows it to run more boost without detonation. The link was very useful.

Having a turbo petrol car myself, I would find this worrying if I'd not always filled the car with vpower from new. I'm not about to switch after the tesco/silica in petrol debacle anyway...

I will try and run the tank out dry and switch to shell ... I can then only report back if the car returns to it's normal performance.
You do know it all comes out of the same tap at the refinery?........ If it is the fuel its more likely a cockup at the petrol station than the refinery.
Given the current weather it could have been damp in the electrics, if it were me I’d be making sure I had the answer before slating a company that may not be at fault, especially one as litigious as Tesco smile
I agree .. note POSSIBLE !

The car is always garaged and thus would not be damp ... the car is 'relatively' new ..
However, in the content of your initial post you have moved from a possibility to a certainty!

If you have run it nearly empty could you not of swilled some rubbish up from the bottom of the tank when refueling?

It's possible to get a bad batch of fuel, but how exactly do you suggest everyone who uses Tesco 99 should play it safe?

You are basically saying everyone should boycott Tesco99 until you have got round to burning all your fuel off and then trying it on another batch. Thats a bit of an extreme thing to suggest based on your one experience of a car that may have a fault you haven't diagnosed yet, or indeed from a bad fuel batch from a single UK garage.

If the diagnostic garage thinks it the fuel, why didn't they drain your tank and fill it up with something else? Thats the logical approach is it not? So it costs you £50 in junked fuel that might in fact be OK, but it's less than an hours labour at a lot of garages now and at least you could then come on here and make a post that might be of some value to others, right now you are making huge assumptions and suggesting a companies product should be boycotted based on those assumptions.

If the car isnt designed to take advantage of higher octane fuels, it wont make any difference. According to their website Renault apparently spec standard 95Ron fuel for a 1.2 clio wink

All valid points ... But I took a vid of the device pulling the data ....

Reason for the Super unleaded for the uneducated, more cleaning agents and even in a 1.2 Turbo you can feel the difference ...
You've certainly noticed the difference!

So it's in limp home mode, but there's no faults stored? That's very odd, you would assume the fault that is causing limp home mode to be activated would be stored...
Our 2nd Clio 197 had that issue. Was running like a dog, eventually went into limp home mode with limited revs and the engine check light coming on. AA man came out couldn't find a fault and neither could the dealer.

No ecu fault codes???

Misfires or duff lambda readings will all be logged by the OBD unless the French wiring system has faults it can't trace.



It's French so my bet it'll be a duff injector/s teacher

Cobblers. "Feel" is mainly psychology, go get a racelogic and show us.

As for it being Tesco's falt and causing a widespread panic, go get it properly diagnosed and then report back. I bet we never hear from you again. You ran it almost empty, I bet some crap from the bottom of the tank has fecked your engine, rather than it being Tesco's fault.

Why is this worthy of a post?

Not as much as I doubt your off the cuff WARNING about Tesco's fuel.

Given the evidence so far how can you be so sure it is them to blame?

Whilst I'm not saying op has come to the correct conclusion, I'm rather concerned about the suggestion that it could be crud in the fuel tank or damp in the electrics on such a new car.

Surely both situations are stretching probability somewhat? I've run my 20 year old 205 and numerous other cars virtually dry several times and not had such problems.

Are you harking back to last year when tesco had genuine problems with their fuel being contaminated? Those stories were widespread, but i've not read or heard about any problems since.

As the others have said, my money's on a mechanical fault, not the petrol.

The suggestion is as correct as the OPs conclusion that fuel is the cause.
