As for a standard car,,,,, well the ECU does 'learn' what fuel your using, thats why some companies claim that you use less fuel on super therfore saving money,,,,HHMMM.

Your T5 will after 10 miles of driving learn that super is in it and wind off the fuel... The difference being that if you need more it's there in the form of increased octane.

The other way to cope with this is to increase your fuel pressure with a remap but most remaps insist on super anyway because it saves you having to change your injectors and fuel pump to cope with the increased power.

Having said all this volvos do cut the ignition before the engine killer 'deting' happens.

Sorry georgey dee,

but pretty much all the above is totally wrong!!
