Supermarket Fuel, Facts Please
Discussion
Shell's decoupling of the VPower/Regular price gap over the last year has done a good job of driving me (ho-ho!) to Tesco Momentum anyway.
I'm doing the thing of still using them every 4th tank or so, which I accept may be pointless but it's been saving me £6-£8 every week. Which in isolation sounds like nothing but across a year is basically the insurance or will take the sting out of a service.
Not seen any difference in performance from the VPower days and the exhausts soot up at the same rate. The upswing in Shell's driver club bonus points/rewards/offers emails has been satisfying.

I have empirical evidence that:
(1) If you are happy filling up your car(s) with supermarket fuel then continue to do so.
(2) If you detect an improvement in using branded fuel (power/economy and/or emissions) and you can afford to do so, then f
k what a PH keyboard warrior says and continue to do so.

7.5 - 10% depending on brand, eu directive.
5%.https://www.esso.co.uk/fuels-faqs
I haven't seen any of the 10% stuff anywhere in the UK (yet).
More ethanol content is not good for your pride and joy (unless it's a dragster, and even then it isn:t really) so perhaps it is worth seeking out the brands who offer 0% ethanol content.

Like some here I have moved away from Vpower petrol and onto tesco Momentum due to difficulty in swallowing the fuel pricing baloney.
Having said that I treat fuel systems with sea foam every 3k or so, the proper 2 fl oz per {US}gallon dosage converted to litres which ain't inexpensive...
As for Fuel quality, never mind Shell super, try and find Esso super
My big issue is the nearest garage to sell it is 8 miles away and is a co-op franchise
and it's akin to buying gold dust.....
Oh to those who say there octane rating makes no difference, well that's what knock sensors do!

It's relevant to the whole supermarket vs alleged premium fuel debate.
Shell wasn't better then- what makes you think it is now? Advertising?
Maybe not Shell - but Esso Supreme is better due to 0% ethanol content.Shell wasn't better then- what makes you think it is now? Advertising?
Supermarket fuels all contain ethanol.
That isn't due to advertising, it's due to different products.
Op, I used to have an Astra j 1.7 125, yes that the high preferomace super tuned version of the 1.7
If I ran it on super diesel the engine vibrated more, as the key ring on the key vibrated really annoyingly. This stopped as soon as I switched back to normal and vice Versa. I decided this probably wasn’t a good thing so went back to supermarket.

Going back 14 years here (before ethanol added?) so bear with me.....
Bought Mondeo off workmate and it stuttered at 2.5k revs (whatever gear), he suggested as he'd pressure washed engine bay that connectors may need drying, so tried that and got no improvement. Only minor so didn't bother chasing it around. We moved house (120 miles away) and the problem went - it was only after a few weeks I noticed (I did say it was minor). Several months later we went on holiday and going up the A1 at steady speed (2.5k revs) it was doing it again pretty much continually. Then the penny dropped... I asked my Wife where she'd filled it, turns out it was Tesco a few miles away, and up until then we used the local Sainsburys. Guy I bought the car from lived near an Asda and had always filled it there, when we bought it we used our local Tesco (until we moved house). Continuing out journey up the A1, when the level went down somewhat we filled with BP (I think, certainly not Tesco) and it didn't have the problem any more until I did a little experiment over the next few weeks.... Whenever it had Tesco in it the engine had a stutter at 2.5k, no question about it - it was too much of a coincidence.

So, about those facts then.
It's not some great mystery of an industry - there must be someone reading who is qualified to comment on the potential differences?
- additives; composition, R&D etc
- exact blend of biofuel
- tank/pump/supply maintenance regime
- Supply route / turnover
... are just some random things that come to mind that might differ between retailers & affect the consumer.
