> A 7p per litre difference does sound like the difference between local station and motorway prices though, and they probably will have factored in that opportunity cost of time...
Only 7p?
Motorway services have shocking price markups, way more than 7p. Most people don't realise this or are just too lazy to find something that isn't quite as convenient.
According to the live feed at https://www.rac.co.uk/drive/advice/fuel-watch/ I see:
Unleaded is 131.80p (UK wide) and 156.80p (Motorway Service Area).
Last time I drove into a motorway services and saw prices ~20p/litre higher I just drove through the petrol station and found a local garage to fill up at.
Petrol in the U.K. is insanely cheap. When I passed my test I could buy 4.5 litres with an hours work at minimum wage, which would get me about 30 miles. Today an hour at minimum wage gets me 9.4 litres and takes me over 100 miles.
Spending an extra £10 once or twice a year when driving a few hundred miles and thus needing to fill up at a motorway is nothing. Chances are I’m spending that much on an overpriced coffee when I do that anyway.
