A couple of weeks ago it was the same near me, tuxedo - but when I went to fill up on Friday petrol was £1.449 and diesel £1.489. I scratched my head a bit - the garagiste said that it would be dearer next week. All a bit baffling; that garage has been consistently cheaper than others for months if not years.
Fuel duty increased by 2 shillings a gallon during the 1960s, a hefty whack when the cost of petrol was 2s8d in 1960, rising to 4s6d. It caused a lot of discontent.
