I travel to work daily, a round trip of some 60 miles. If we keep getting these weekly increases in fuel then it will come to the point where its not cost effective to work.
I'm sure diesel is more because greedy old government realise that diesel give more mpg, hence the higher price, I dont think it costs as much to produce as petrol. Also there are a large proportion of business users buying diesel so there is a large demand, untl they start saying no prices will just continue to rise.
Perhaps we would have been better off not going to war with Iraq, we may not have seen these rises
