I kinda knew that the source for the different companies would be more or less the same, didn't know about Statoil connection, but my symptoms have definitely disappeared, just can't explain it.
Maybe I will get another fill from the Tesco outlet, just to confirm this for myself.
I just should also mention that my MPG seemed to disimprove with the Tesco branded petrol, so what you save on the swings, you lose on the roundabouts.

We were being ripped off and knew that we were being ripped off for so long by the established garages that we leapt at the chance of giving them a bloody nose.
irishpancake said:I was just wondering has anyone noticed whether Tesco Petrol causes engine pinking or loss of power/under-performance.
I am asking because I have stopped using Tesco, as my 2004 Peugeot 307 was pinking and losing power when I used this petrol.
I had it in the garage, and they could find nothing wriong with ignition/timing etc.
Since i have gone back to my old Texaco petrol supplier, these symptoms have disappeared, and the car feels better to drive, with more power and no pinking.
I just wonder whether the Tesco petrol is just a little inferior.

europhile said:What's "pinking"?
Knocking (also called pinking or pinging)—technically detonation—in internal combustion engines occurs when fuel/air mixture in the cylinder has been ignited by the spark plug and the smooth burning is interrupted by the unburned mixture in the combustion chamber exploding before the flame front can reach it. Combusting stops suddenly, because of the explosion, before the optimum moment of the four-stroke cycle. The resulting shockwave reverberates in the combustion chamber and pressures increase catastrophically, creating a characteristic metallic "pinging" sound.
