For the last few days there have been many reports of damage to car oxygen sensors in England’s south east. This seems to have been cause by faulty fuel supplied by some supermarker chains, including Tesco and Morrison’s. Initial reports suggested the fuel was up to standard but one wonders if this is a consequence of not applying the correct tests. Expecially now that reports are emerging (for instance from The BBC) that indeed there is a contamination arising from silcon, probably from silcone contaminants. Silicones are used in diesel but damage high-tech petrol engines.

The silicones were probably introduced inadvertantly at storage rather than at the refinery stage.

This is going to get expensive for someone as it sounds as though thousands of cars have been affected.
