    I wonder if this could be deliberate? Two possible culprits fit the frame - one or other of the really loony anti-car protesters and the people who are hardest hit by the supermarket fuel trading, the independent petroleum retailers association.

    Okay! I am being paranoid.

    I suspect the problem is that todays cars are so technical that if something gets into the petrol that was not anticipated, it can screw the whole system up.

    I know of a problem with a car that kept misfiring at high speed on the motorway. It was eventually passed by the main dealer to a small garage run by a friend of mine, who is very good with computer systems. It took him a long time to solve it - but he eventually found the cause was POOR WELDING when the car was repaired after an accident. Whilst I studied physics, I could not understand this. So he explained that the car's bodywork acts as an earth. Poor welding will allow direct currant to be earthed but may not allow RF(radio frequency) earthing. At high speed the engine management computer sends a message to the fuel system to send more fuel. But the message was inducing a signal in the bodywork that was not properly earthed. The car's own wiring was picking up this faint echo in the bodywork and interpretting it as a request to send less fuel! Once the welding had been re-done the problem went away.

    I sometimes worry that fly by wire aircraft are a bit too complicated.

    They are! The FD crew has no direct control over an Airbus. If it ain't Boeing, I ain't going!

    All this blab about how it`s going to cost the supermarkets millions of pounds in compensation is rubbish because they will claim it back from the refinery responsible. And where will the refinery get it from? Us, the poor sodding motorist, prices have already gone up here in South Wales, and we were unaffected by the contamination. David.

    Tis the insurance companies that will pay - but your right, if companies premiums rise, then it will the motorist that will pay.
