As well as being a V7 cafe owner, I am a retired tanker driver and oil terminal supervisor, who worked in the industry during the introduction of additives, supermarket supplies and the dreaded ethanol.
Be careful if you think all Esso, Shell and BP high end grades are ethanol free - it depends on where in the country the filling station is supplied from. 
If the supply terminal is located on the UK pipeline systems, for example Kingsbury in the Midlands, then Ethanol cannot travel in the pipeline ( all to do with avaiation fuel contamination). So, Ethanol is not contained in the base fuel, but is added when the fuel is loaded onto the tanker at the distribution terminal. Thus allowing the major fuel companies to keep Ethanol out of the high end grades. 
But if the filling station is supplied from Grangemouth refinery in Scotland, so read all of Scotland and quite a bit of Northern England, then nothing is transfered by pipeline and (so far as I am aware) Ethanol is present in all grades, including high end grades. Could also apply to other distribution terminals that are fed by ship. At one time She’ll we’re trucking high end grades up from Stanlow on Merseyside to Central Scotland, but I am not sure if this still goes on. 

As for additives; the supermarkets drive a hard deal with the suppliers, and to get their prices down it is possible that they take very little additives, (which like Ethanol are added when the tanker is loaded). The major fuel companies, on the other hand always add their own specific additive package, and if it’s a high end grade, then there is a high end additive package, which is quite an expensive product.
So it’s like every thing in life - you pays your money you gets your choice. Cheap fuel, from wherever you buy it is exactly what it says on the tin..... High end grades are indeed high end fuel......

Shell V-Power is indeed distilled to 99 RON plus.  Unlike other fuels Shell V-Power is not sourced from local refineries, high octane Shell V-Power (in GB) all comes from one refinery (*)

As said before, apart from the octane rating it is the additive package which differentiates the brands. The oil major additives are all bespoke, developed & tested exhaustively in-house. Supermarkets buy generic additive packages based on what they are prepared to pay. If you/Morr isons etc. tried running an engine on raw gasoline distillate bought ex-refinery you'd be decoking that engine frequently in an authentic 1930s experience.

To be clear, the oil companies do not wish or choose to add ethanol to their petrol. That requirement comes from the Government. Oil companies have to comply if they wish to keep their licence to sell fuels in the UK.

Hi all,
Just seen this thread and thought I'd add my experience of V-Power fuel.
A few years ago, when my son was kart racing, we found that FRESH V-Power was the best fuel we could get (we tried all of the companies premium fuels). We could only use it in 'clubbies' because when we were doing British championship rounds, we had to use the control fuel, which was frankly all over the place, one batch being vastly different to the next, possibly due to ageing.
Anyway, with the V-Power we ALWAYS bought it from a well used site for good turnover in the bulk tanks and ALWAYS dumped any we had left over at the end of the weekend.
If you left it in the tank, or even if it was stored in a 5 litre can, it would go off within two weeks, i.e. if we tried to use it at the next event the engine would cough and stutter under acceleration. Not good. With the money we were throwing at the racing, it wasn't worth chancing it over the cost of 5 or 10 litres of petrol!!
But it is good petrol, if you use it up.

These are very interesting bits of info. Do we think that all super petrol goes off in a few weeks?

I don't know whether it would show up as badly on what is, let's face it, a pretty low state of tune such as is found on my 750 Breva.
Those kart engines were pushed pretty hard, revving to 22000 sometimes and with a lifespan measured in minutes not hours, let alone thousands of miles.
But imo the fact is that the petrol loses its 'edge' pretty quickly and we all know better than to leave it in the tank over winter, don't we??
Of course, I'm joking but it definitely goes off in time. I'm considering draining both my bikes tanks and putting a couple of litres of Aspen fuel in for over wintering.
Of course, I'm old and a wimp Smile - if you use your bike regularly throughout the year there's no problem.

Back when my only transport was a bike I used to regularly fill up every Friday on my way home from work so the thought of petrol going off never occurred to me. Funny old world, innit!Smile

We have a lot of good riding days in winter. I've never seen the point of mothballing the bikes.

Maybe you have so far been spared arthritis so far from doing just that

At 65 the bike is still my only means of transport and is in use virtually every day. I'm lucky, I do have aches and pains but nothing debilitating. So the petrol in the tank never gets the chance to go off and with regular usage, I'm hoping the same will apply to me.

Never seeming to learn my lesson, I have tried posh petrol in my V7 Classic three times over the last few
 years. First was a Christmas present to my bike of a tankful of BP Ultimate, second time was Shell V Power because I felt sure the fact that it ran like a pig after using Ultimate could have nothing to do with using posh petrol.
Third time was recently when I filled brim full of Esso Supreme having been told it is the only UK petrol that really is ethanol free.
How painfully long it seemed to take to use up that tank of fuel with the engine feeling sick! 
I stick now only to proper brand petrol (mainly BP, Shell or Jet locally), but I will never again stray away from ordinary petrol ordinaire. That is what the handbook says “95 Octane and no additives” and b@gger me it’s right!

Your signature  suggests  you have a Rokon  , surely a few potholes would be no problem to one of them!!!
