In answer to your question:
Fault: The electrodewill break off due to pre ignition
Check: for correct heat range and as for 'overheating'
Thats from the back page of the haynes manual.
If your talking about the white stuff breaking off, thats caused by detonation or the wrong gap setting.

Right, i think the standard unleaded is definately the problem!
Higher ocatne fuel like 98 ron has aditives in it to STOP it combusting at lower pressures. If you have an engine with a fairly high compression ratio or even a turbo and you put lower octane fuelin then yes it will pre-ignite. It will self combust with the pressure before the spark plug does it.
Just get a few tank fulls of optimax through the car to clear the old stuff out... should be ok after that.
