For me its, Supermarket splosh in the car but Superfuel in the bikes. 😎
(As long as your bike's engine can cope with the full potential of Superfuel of course.)

It'd take considerable time and effort for me to fill at a supermarket. None of them sell petrol round here. Okay - there's one Tesco that does - but it's 10 mile away. The issue for me is the pump at the local shop for local people in the village here. It's Rix branded petrol (and there's also a single diesel pump) and I'm paranoid there's a lot of sediment lurking in the ancient tanks. Also it's really dear.

With an older Vauxhall diesel car I had, I could actually tell the difference when using supermarket or actual petrol station fuel - the difference was dramatic. So much so that for those extra pennies for petrol station prices I ended up getting more MPG. The engine was livelier and just ran better - it wasn't working as hard to get to places.

To be fair I think supermarket fuel quality has improved these last few years? That or petrol station stuff has decreased in quality..

For my current car (Leon 184) I just use normal fuels. Using those 'better' fuels at pumps doesn't make any difference as far as I can tell. I won't have the car long anyway so being cleaner inside makes no difference to me.

For my 404DS I don't give a shit - I'm just happy I've found a fuel source before I had to push it!

I have actually been thinking about this very subject. Was thinking about using premium unleaded but as I only have a 125 I doubt it will make any difference.

My thoughts were purely about looking after the engine better rather than performance.

Got much better MPG in an 08 Passat with premium fuel. My X reg fiat van hated it and ran really badly though.

MPG on bike seems to be up when I use premium but not as obvious as it is in the car.

Esso super unleaded petrol (Synergy Supreme+ Unleaded 97) is ethanol free (except in Devon, Cornwall, the Teesside area and Scotland). We would therefore advise anyone who has concerns about the presence of ethanol in petrol to use Synergy Supreme+ – providing they do not fill up in Devon or Cornwall, the Teesside area or Scotland.
is the reason I buy it ... yeah it's a 125 ..but I get 86mpg and I like to use it ...

I have never found a problem with any supermarket fuel. I think that "supermarket fuel is inferior" or "to get the best, squirt in a shot of shitex" is a myth.

Supposedly, it's not the fuel itself which is shitty from supermarkets etc it's the tanks they're stored in. There's more shit in them leading to poor fuelling.

Seeing as they all come from the same refineries then I would be inclined to believe this.

Our old diesel Auris hated Tesco fuel, it ran like shit and the EGR would jam up in no time. I'm not an advocate of 'premium' fuels since, in my opinion, it's a load of bollocks but I do only put BP (standard) in our vehicles and have had less trouble than filling up from supermarket pumps over the years.

So, TL; DR: The only difference are the additives which give the fuel better properties, so using the more expensive fuel (not necessary) means higher mileage. At least that's my experience.

However, the extra cost is not worth the money and if you do wish so, you may just add those additives to your fuel tank yourself.

If it's true that "super" is ethanol free then that's where the gain in mpg is. Ethanol has 34% less energy that petrol. The other additives are just marketing IMO. If the fuel was 10:90 that's 3% less energy so not a huge difference in mpg.

In years of using petrol from anywhere I happened to pitch up at, be it motorway services, local Esso, supermarket or village pump I've only once had an issue. There used to be a small car dealership with some old forecourt pumps on the A41 near Aylesbury 'branded' as "Delicious Petrol." The Kawasaki lurched terribly until the tank was empty, presumably due to water in the fuel. It was fine on the next tank full.

When I renovated the Kawasaki a couple of years ago after a long lay-off (I'd been using the R1) I drained the full tank into several jugs, filtered the fuel through a cloth leaving the lower, coffee-coloured later in the last jug, and put the fuel into my car with a full tank of petrol. I was wary but there was no problem with the car at all.
