Obviously the price hikes of the past few months have got us all seething but I'm more interested at the moment at the surge of diesel prices vs petrol prices. Diesel always used to be 2-3p per litre more than petrol, but at the moment it's anything up to 10p more per litre! What gives? Why the sudden extra burden for oil burners? And surely given the lower CO2 emissions of DERV we should be paying LESS, not more?
