The average cost for a litre of unleaded has soared to £1.33, which is the highest level since October 2013, data from the AA reveals. Prices have been rising continuously since late November last year, when the average cost was £1.14 a litre. Diesel costs have followed a similar trajectory, rising from £1.17 in November to £1.35 last week, according to the AA.
This means a full tank for a 55-litre family car will set you back £73.15 to fill up with unleaded, and £74.66 for diesel – although the AA data does reveal that prices can vary by as much as 8p a litre depending on the garage, with Asda’s forecourts currently coming in cheapest on average for both unleaded and diesel.
