In the UK, all pump gasolines and diesels are governed by various national and international standards – notably European and CEN Standards.
These require vehicle fuels to conform to minimum world-agreed quality and performance standards… so in Europe, supermarket fuel is as good as any.

While they conform to the same standard, they are not all the same.
For example, tesco momentum has 5% ethanol while most BP super unleaded has none. It's because pure ethanol is around 140 octane so upping the ethanol content is an inexpensive way of increasing the octane rating of cheap fuel.
Problems with fuel system componants on older vehicles aside, the higher ethanol content fuel has a lower energy density. You get less bang per ml out of it.
Probably not noticeable for most vehicles but to assert they are all as good as one another because they conform the the same standard is inaccurate. Bells and Balvenie both conform the the standard for Scotch whisky but they are not as good as one another.
What comes out of my kitchen tap in Cumbria conforms to the same drinking water standard as what comes out of a tap in London but I know which I'd rather drink. ____________________ “Rule one: Always stick around for one more drink.

Ethanol is about 90% as energy dense. So with a 5% ethanol content, you get 99.5% of the efficiency; with 10%, you get 99%.
Air temperature will have a much larger effect, in the region of 1.5% every 5 degrees.
Ethanol will also help remove water from your petrol tank. ____________________ Bikes: S1000R, SH350; Exes: Vity 125, PS125, YBR125, ER6f, VFR800, Brutale 920, CB600F, SH300x4

I thought lead had been dispensed with before the introduction of ethanol came along? ____________________ Chickenystripgeezer's Biking Life (Latest update 19/10/18) Belgium, France, Italy, Austria tour 2016 Picos de Europa, Pyrenees and French Alps tour 2017 Scotland Trip 1, now with BONUS FEATURE edit, 5/10/19, on page 2 Scotland Trip 2 Luxembourg, Black Forest, Switzerland, Vosges Trip 2017

I remember probably 15 years ago iirc there was an issue with supermarket fuels gumming engines up, after they had to pay to fix punters engines they stopped selling piss water.
That's how i remember it anyway, i did smoke a lot of weed back then so could well be in my imagination. ____________________ aprilia 125 Af1 Futura >> Suzuki gsxr 600 srad >> J1 zx6r >> cbr 600rr >> Speed Triple |

I seem to remember there was something that was in the news a good while back about supermarket fuels that made people mistrust them. Something to do with contaminated storage, perhaps? I would have thought that issue would have been resolved by now though? ____________________ Chickenystripgeezer's Biking Life (Latest update 19/10/18) Belgium, France, Italy, Austria tour 2016 Picos de Europa, Pyrenees and French Alps tour 2017 Scotland Trip 1, now with BONUS FEATURE edit, 5/10/19, on page 2 Scotland Trip 2 Luxembourg, Black Forest, Switzerland, Vosges Trip 2017
