Warning POSSIBLE Tesco 99 Poor fuel problem
Discussion
Just a heads up but I am 99% sure Tesco have a problem with the 99 Fuel.
I filled the wife's 2008 Renault 1.2 TCE from almost empty, and after 20 miles the car went into limp mode.
I have had it checked, and no faults are found.
Car is now running rough on tickover and lacks power, I assume the ECU has backed everything off.
I am certain the problem is the Super unleaded bought from Tesco Sidcup and no faults with the car.

I understand the thoughts you are all having.
The car since new has run 'sweet'
Obviously the only way to prove this is to sample the fuel ..
The 20 miles was approx.
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.
I still feel if you plan to use Tesco 99, play it safe for now .......
If the car had any problems I am sure they would have fixed it .... they suggest it is the fuel too

Surely the reason for super unleaded is a higher octane, and on a car with a knock sensor it will get more power out of it? On an engine not equipped with a knock sensor it will just work as "normal".
Correct, the Clio's engine is the latest and advances the ignition.Edited by AndrewW-G on Saturday 28th November 17:55

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
The car is always garaged and thus would not be damp ... the car is 'relatively' new ..

My garage is heated and dry, makes f
k all difference as soon as I open the door and drive off into the currently rather wet out doorsjohnfelstead said:

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? If the car had any problems I am sure they would have fixed it .... they suggest it is the fuel too
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.

Frankly, if your car goes into a "limp home" type mode without recording a fault, it's broken. No piece of electronics should actively enter a diagnostics mode without recording the reason. If the fuel was bad and there was nothing wrong with the car, it would have recorded that it was having some kind of combustion problem, probably a misfire or overheating or something.
No over heating or misfire .... Marf said:

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.How did the crud get there in the first place?
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?
As you can see peoples level of knowledge of cars is amazingly poor.
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.

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.

John,
exactly as I understand it ... your post an enjoyable read ...
Thanks
Andy
But your car tells you to put 95 to 98 in, not 99. So you have what John said is an 'old' car. Your car can't handle it and popped, so it seems.exactly as I understand it ... your post an enjoyable read ...
Thanks
Andy
