For tuned cars only- BPs 102 RON fuel from pumps

[Jerez]

Just out of interest and this about a 18 mnths old now:

BP is targeting the trackday market by launching the highest-octane fuel on sale in the United Kingdom.
BP Ultimate 102 has a RON rating of 102, higher than Tesco's 99 RON super unleaded and Shell Optimax, which is 98 RON. The new fuel will only be available at half a dozen outlets across the country, although BP says it might expand its availability if demand proves sufficient.
BP says that only 'tuned cars' will benefit from Ultimate 102's extra performance. It claims that in its tests with tuned vehicles, the fuel gave between 4 and 7.5 per cent more power than its regular 97 RON Ultimate Unleaded. Evo owners take note, though - on a turbocharged vehicle with increased boost pressure, Ultimate 102 increased grunt by 8.6 per cent overall, and by as much as a 16 per cent at certain points in the rev range.
If you want to try Ultimate 102 for yourself, chances are you'll have to travel to get it. It's only available at the following sites - Tudor Filling Station in Maidstone, Chicheley Park Connect in Newport Pagnell, Wavendon Gate Connect in Milton Keynes, All Saints Self Serve in Portsmouth, Newbury Centre Filling Station in Newbury Park and Newham Way Service Station in Canning Town, London.
And the price? Sources suggest that Ultimate 102 will set you back £2.42 per litre - which will bring a tear to the eye almost as quickly as the fumes, one suspects...

Well, I'd have to drive 150 kms to get to te closest station-- bummer

We can only get the 98 in a 20l can from select BP outlets!

95RON already costs so much, imagine what they would charge us for anything higher

For those who may not know how the modern day car works , here goes. Simply your car has Lambda or oxygen sensors in the exhaust and manifold and these determine how much fuel must go through the injectors to get to the ecu rating. The ECU is mostly set to STroich (14to 1 or 14.7to 1 ) depending on where you are. BMW if you look on fuel filler cap you will find "10per cent ethanol allowed". Put this in a tank of 95 octane fuel (50litres 95 + 5L ethanol) and you end up with close to 98 octane. Your vehicles lambda will pick this up because ethanol is not as dense as 95 octane fuel and supply more fuel all by itself. On a performance vehicle with own management you would have to bring the AFR ratio to 11.5 as opposed to say 13.4 . You will no longer get the same fuel consumption. Theoretically 10 percent less.
The next trick is your car has knock sensors to pick up detonation. As you drive this sensor will adjust the cars timing to optimal. I have seen on some vehicles timing advance as much as 10 degrees. Car does it all on its own you do not even need a mechanic. I would like to list power output differences on three vehicles by just going to what BMW allow.

1) volvo 2.0 turbo s60 standard 132kw after 157kw 12-20deg
2) focus st 2.5 turbo standard 166kw after 172kw 10-22deg
3) bmw 335I n54 standard 225kw after 237kw 14-20deg

So yes what they say is not so new or even special. Any brand will increase the power output on your vehicle if the octane number is upped. Bear in mind that vehicles with higher compression benefit more because the higher the compression the lower you timing curve. Nomal aspirated vehicles need not apply as there in my experience is no benefit.

IMO every BMW fanatic should take what is on offer, your car will reward you for it. Please do not exceed the 10 percent BMW allow you as there are negative chemical reactions that will take place. The engineers are very learned people.:thumbs:

There was a time when you could buy 105 from the depot in Rossborough. In drums that is.

BP outlets, close to tracks offer these fuels and promote them as fuel for high performance cars. There isn't a large market for it as its around £2,40/ltr.

That's a great explanation but I can only speak from my own experience re high octane fuels
Some 23 yrs ago, I stuck 105 in my 1.8 Cli Jetta and made mince meat of a e36 325i from stand still until 4th gear.
The car never performed like that before and never did again as I only used it once.

I can testify, my vw cli 8v on 102RON mix outran my buddies 16v for the duration of the mixture until 4th gear too..

Information was more related to the modern day car. Like to add that the vw motor IMO is one of the greats and in the company of other 4cyl like the ford Xflow and Toyota 4AGE. Back in those days the first thing you did on a N/A motor was skim the head and bump up the compression ratio. The higher the compression the more efficiency therefore more TQ and KW. Those motors were already 10 to 1, so yes, if the head was skimmed and compression higher the higher octane would definitely have been a benefit to the car. In general 8valve motors have more torque, that you need of the line,than 16valve motors so no surprise there. The 16valve motor relies on the power band rather being higher up on the rev range. The Golf GTI was always great on the quarter mile because of the 8valve torque off the line and the low weight of 860kg.:thumbs:

hi , what grade of ethanol ? 95 , 96 , 99 or 99,9 which one do you mix with ?:thumbs:
