Could be that you ran the tank very low before filling up? If this happened the pump will have picked up all the crud from the bottom of the tank.
biggest misconception out there.....
t are more concentrated when there is less fuel. I'd be interested to know why you think otherwise.

Wouldn't any cars fuel system pick up crud as a matter of course given they pick up fuel from the lowest point in the tank?
What is a fuel filter for?

Why on earth are you running a 1.2 on super for starters...
He said earlier in the thread that he was using it in part because of the better detergents and additives etc in the fuel, which i can't find fault with TBH.

As you can see peoples level of knowledge of cars is amazingly poor.

As has been said it's the concentration levels. I've pulled apart fuel systems that have run for years and upon opening them up still seen debris.
Dave!
Just to update for the people who do understand.
I have spoken to Greenenergy who were extremely helpful.
They are going to investigate to check if any problems during the delivery of the fuel..
The gentleman did explain they can have very occasional issues.
I am currently unable to get any of my local Renault dealers to check and drain the tank as they are all booked until Thursday... and I need to use the car.
So I plan to run the tank out and refill with shell/BP.

My last cars engine went pop on Tesco 99. The only other car to do the same thing we knew of at the time was also running Tesco 99.
The ingredients used to make it 99 are not appreciated by especially some older engines so if you run an older car with it make sure it wont damage it first.
I went back to Shell after that and have never used Tesco fuel in my cars since. My Dad uses the normal 95 ron from Tesco all the time though especially with 5p a litre off. I wouldn't use Tescos 99 again though only V Power.
Sorry, but your car's engine blew due to Tesco's petrol? I don't mean to be funny but I think it's more likely you engine had some sort of internal problems prior to you filling up.The ingredients used to make it 99 are not appreciated by especially some older engines so if you run an older car with it make sure it wont damage it first.

I've filled my ST up with Tesco 99 for the past couple of weeks without any issues so far (touching wood) so if it is a bad batch of fuel it could be regional like last time, although i haven't heard anything about anybody else having issues.
It does seem to run a bit sharper on V power though.

I wouldn't expect it to be a problem with the specific fuel batch or mixture. More likely water in the fuel from a leaking, rusty old petrol station tank, if the fuel is indeed the problem with the car.
You never know, you might have been the one bloke who had the last tank out of it before it got its weekly refill, and have a car that's sensitive enough to pick up the difference.
Oh and all this talk with knock sensors and such meaning the car 'pick's up' better fuel, just fill it with whatever the manufacturer has stuck on the inside of the fuel cap. Even if it has a knock sensor, if the manufacturer recommends 95 octane, beyond any extra detergents, sticking 98 in wont make any difference. The car will only pink/knock, and thus make any adjustment if it's received fuel worse than it is expecting, there isn't some magic sensor that can tell whether it's 95 or 98.
If the manufacturer recommends 98 with a minumum of 95, then it's mapped to 98 Octane and that's what you should use. If you fill it with 95 then you're relying on the ECU's engine protection strategy to avoid any damage. Perhaps an acceptable risk in a normally aspirated car, but I would never fill a forced induction car with anything less than manufacturer's recommendation unless it was an emergency
