Think what he is getting at where is it defined that they have to put "premium" and "super".

E.g. whats stopping a petrol station putting super on a 95RON pump?

I don't know the answer or care but I think thats what he means

Sadly it seems you have to pay to read the bs228 doc but It's academic as no fuel company calls 95 Ron Super. It is at the least an accepted convention.

This was much easier when we had 2, 3 and 4 star. (And a long time ago, 5 star)

Anyone know how those map up to the current naming scheme?

[TW]Fox · 27 Sep 2010 at 16:02

seems there is a standard for super. but you can't read it without paying.

I'd imagine fuel companies don't want people knowing the additives? Or is that the "tinfoil hat" inside me?

LOL, we all want someone to confirm that all 95 is sold under the word "premium" and Fox won't say it in case it's not 100% true. I'm thoroughly enjoying this.

2* 90 octane
3* 94 octane
4* 97 octane
5* 100 octane

I'm not sure why I feel the need to do this, but I have access to British standards Online through my Mechanical engineering degree so I'm downloading 228 now

To the OP,

Depending on what car you drive - You may well notice a difference in performance and economy

That doesn't have the classification of octanes, but only has this one relevant part:

NB.2.1 Pump marking
For the purposes of this British Standard the following information shall be marked on each dispensing
pump or container used for delivering petrol conforming to this British Standard into the consuming
vehicle.
a) The name or mark of the supplier or vendor of the petrol.
b) The grade designation ‘‘Premium Unleaded 95 BS EN 228’’ displayed as shown in Figure NB.1. The
minimum dimensions of this mark shall be as shown in Figure NB.1 (see Note 1) and the colour used for
the design and lettering shall be in clear contrast to the background (see Note 2).
The mark shall be in a position where it can be seen by the person dispensing fuel.

[TW]Fox · 27 Sep 2010 at 18:36

So there we have it - BS 228 decrees that 95 RON fuel sold in this country should be sold as PREMIUM UNLEADED. Who'd have thought that.

So..

The British Standards organisation. Next? It's just a shame I didn't have paid access to prove you wrong earlier, you could have just taken my word for it I guess.

Another case of MikeHiow having no idea, but dispensing 'fact' as if he did.

Premium is just a name, it is normal unleaded.

There is no governing body to set standards for different grades (normal, premium or super)

Why do you say these things when you dont really know?

Uriel · 27 Sep 2010 at 18:59

It's EN, as well as BS, so a Eurocode then. That standard applies throughout Europe.

BS and EN are wrong - MikeHiow is always right. For all this wading through the various arguments in this thread, if you want the proper answer, it can be found in post 8:

I'm perfectly capable of admitting when I'm wrong, although this hasn't been enough for you in the past, and no doubt will not be enough this time to avoid it being brought up out of context every time your argument fails (as is your usual behaviour).

Regardless of me being wrong, and BS stating that 95 = Premium (for consistency, I imagine) you make it sound like its something special when you continually mention that "Premium is the lowest grade we have in this country" - which it is not.

You amaze me! It's stated that 95 = Premium not 'for consistency' but because.. thats what it's called!

you make it sound like its something special when you continually mention that "Premium is the lowest grade we have in this country" - which it is not.

What are you talking about now?

Premium is the lowest available retail fuel in this country. UK filling stations do not sell anything less than Premium unleaded.

MikeHiow · 27 Sep 2010 at 20:39

But why do you keep calling it Premium? No one does this - Premium implies it is something special when it really is not.

Why else would they give fuel a name (such as Premium) in a standards document if it wasn't for vending consistency - the same reason why they specify the green colour.

Because thats what it's called, and thats what the OP said the pump was called in his opening post. Given that the entire thread is about how the OP didn't understand what Premium was and ended up mistakenly selecting High Octane, I'd say its pretty relevent!

No one does this

Except every petrol station in the country, obviously.

- Premium implies it is something special when it really is not.

Only in isolation - compared with the full spectrum of the available unleaded road fuels in the world it's of premium quality. Hence the name.

If a shop sells only gold and platinum jewellery, it doesn't suddenly mean gold isn't 'special' or of high quality simply because its the lowest grade metal the shop sells?

Durrrrrrr.

Why else would they give fuel a name (such as Premium) in a standards document if it wasn't for vending consistency - the same reason why they specify the green colour.

I find it quite quaint that you are so incapable of realising when you don't really know anything and just giving up that you are now basically trying to argue that the British Standards agency are wrong

Across the whole continent of Europe, and most of the world, 95 RON fuel is Premium but no! MikeHiow knows better! He knows it isnt!
