he doesnt... he just likes to guess

thats what i was thinking

how do you know when it has adjusted ?

Morrisons, sharp and nippy
Asda for 15 miles, sluggish, as though the turbo was not working
Asda after 15 miles, just as nippy as the Morrisons

Try it.

So from that video the engine management needs to adjust to the higher octane petrol being as they reset the engine mangement,if you were to use the lower octane and the switch to the higher how long before the engine adjusts ?.

It will take a good few tanks for it clean out any of the old crap and for your ECU to start sorting itself out.

i suppose there is no point in using it every now and then,sounds like you don`t get the benefits unless you use it all the time.

Now and again is fine.  You never feel any power loss with the higher octane stuff.  You sometimes do with the 95 RON, but not often enough to justify the extra trouble and cost, unless you have some special roads.

You automatically knew this 'power loss' was the petrol ? I thought the whole point of using super is to 'theoretically' give you more, didnt think the standard stuff dropped power in your car, I would have though it just didnt give you anything extra.

There is a big bit of literature somewhere (I think toph knows where it is? ?) on the net that explains how the FSI engine works and the benefits of using the high octane stuff on FSI engines. I canny find it though

I understand that part, but what I dont get is the normal stuff giving you the reverse effect.
