I am used to seeing my USian LJFriends bemoaning $4 / gallon petrol prices and had not bought petrol myself for a while but was surprised to find that petrol is MUCH more expensive over this side of the pond! We are spending up to £1.40 per LITRE! Now, using very rough approximations, there are about $2 per £1 and four litres to a gallon. I know, very rough. Please do let me know if these rough conversions are wildly off. Anyway, using these rough conversions, we are paying £1.40 x 4 x 2 = more than $10 per gallon!!!
ETA: TBH our living and traveling needs are not relevant to the price we are charged for petrol. My reason for this post was not to whine that we are charged more but merely to state the fact that, for whatever reason, we are - whether we have further to drive than you guys or less far to drive.
