Hi,
Friend of mine has a 4 year old BMW mini which recently had the problem pictured below and a £600 bill. The garage have said it was due to using cheap supermarket fuel.
I really don't understand that, surely most likely caused by pre ignition or a very weak mixture. Firstly with all these computers on board modern cars don't they adjust the mixture etc, I thought that the chances of the mixture being weak were negligible, there again the engine is post 1935 so what do I know.
Secondly there has long been a debate that actually super market petrol comes from the same tanks as non supermarket a ron is a ron. Tescos do their own equivalent to shell optimax which many with high performance engines use
I have suggested it might be worth pointing this out to BMW in his usual diplomatic way, he is a blunt Yorkshire man ( I like what I know and I know what I bloody well like ) and see what they have to say about it.
