I wish the press wouldn't keep on about "contaminated" fuel - Tesco can quite rightly deny that.
This explains the REAL problem.
"Tesco is the first major petrol retailer to offer the most environmentally friendly petrol available, to millions of customers in the UK.
More than 150 Tesco petrol stations in South East England are selling standard unleaded petrol, which now contains five per cent bio-ethanol, a renewable product which delivers lower emissions of greenhouse gas, carbon dioxide."
Notice which area the problems are occuring in!!!
