High Octane Unleaded?

This is a bit of a nightmare this subject isn't it :D

A British Standard in itself is obviously not law - it has no legal basis unless legislation mandates it. The legislation which controls the sale of fuel in this country is the Motor Fuels (Composition and Content) Regulations 1999. It is this document which states in one of the annexes that some fuels (ie 95 ron unleaded, if thats what you wish to sell) sold must conform to BS EN 228: 2004. Now from what I can see there has been no ammendment to this legislation since 2007 - therefore nothing which mandates the use of the newer 2008 revision of BS EN 228. There is a consultation documented out on revising this particular peice of legislation but the consultation period is 6 months - which shows you how slowly these things move and makes me think its unlikely that BS EN 288: 2008 is legally mandatory at this time. Therefore I suspect 2004 still applies, which is why pumps still say Premium on them?

No wonder lawyers get paid so much, its heavy stuff :D

Did I just break the anally retentive record?

Tbh it makes me feel like lawyers are probably getting paid too much? Seems entirely logical and relatively simple to me and clearly you, despite us having little to no legal training or professional experience :p
 
The 2007 amendment also answers the Super unleaded question for us..

In this regulation “super unleaded petrol” means petrol that has—

(a)a research octane number of not less than 97 measured in accordance with the Test Method specified .. etc

ie Super is legally 97 or above.

This was the last change to this legislation - so the current version is the 2007 amendment. It is dated before BS EN 228: 2008 was released.
 
I have just got a copy of EN228:2008 which supersedes EN228:2004.

One of the key changes is :

'Premium unleaded petrol' becomes 'unleaded petrol'.

I guess most forecourts now just say Unleaded too - not that I have actually looked.

:rolleyes:

However I've got better things to do than make a big thing about it. :)


Nothing wrong with Ethanol really.
 
"I've just put Normal unleaded in my car"

If I said premium unleaded people would look at me very funny.

Unless you were posting on an American car forum.

If you look under the fuel flap of most cars it will state something like "Premium Unleaded 95 RON gasoline". Anywhere in the world, following that instruction will get you the correct fuel, so if you drive your BMW 320i to America you will have to buy the expensive "premium" petrol" and rednecks will mock you for it.

Its really against my better judgement to fuel this thread further (no pun intended) but I have to point out that:


I have just got a copy of EN228:2008 which supersedes EN228:2004.

One of the key changes is :

'Premium unleaded petrol' becomes 'unleaded petrol'.

I guess most forecourts now just say Unleaded too - not that I have actually looked.

If EN228:2008 supersedes EN228:2004 then that means that when 2008 was published then 2004 was immanently void and anything that refereed to it (i.e The Motor Fuels (Composition and Content) Regulations 1999) now refers to the EN228:2008 standard. At least that is how the legislation works in the Gas Industry when referring to BS/EN documents (and I see no reason why legislation would be different in the petrochemical industry), its done this way so that legislation doesn't have to be amended every time the BS/EN stuff is amended (which is quite often)

I.E current legislation in the gas industry references a BS document from the 1980's however engineers are supposed to know that that document has been superseded multiple times and the 200X one currently applies

I looked under the fuel flap and the is a sticker that says "極度の無鉛" I'm sad now because I didn't know my car was dyslexic, oh well I love it all the same
 
It will say super unleaded cos I got that text string by translating super unleaded into Japanese, I couldn't be arsed looking up each char in word and C&P it to the forum :P yeah its an orange sticker

But wouldnt that effectively make the British Standards Group, a private company, a lawmaking body if anything they publish as a standard is immediately law, superceding previous standards which did have legal precedent?

Either way we are going way off topic now :D

I did call in at a petrol station on the way home which had been recently refurbished as a result of being taken over by another brand. Despite everything being new the stickers on the pump still say 'Premium Unleaded BS EN 228'.

Therefore really the main point still stands - in this country, you will find 95 Ron fuel branded on fuel pumps as Premium Unleaded. Don't confuse it with Super, use it happily in your car. Thats just what its called :p
 
Turns out I was wrong about Japan. They do follow different standards for pretty much everything, but this comes from Shell's Japanese site.

Showa Shell Sekiyu KK said:
JIS standard, more than 89 octane regular, high-octane has been defined as 96 or more.

Elsewhere on the site they appear to state that 98 is common and theirs is 100, but it's hard to be certain given the translation.
