Cardigan Superstore - Petrol Filling Station: 165.9p a litre, 2.4 miles away. 1.0p a litre cheaper: saves 55p a tank, and costs about 90p of fuel to get there and back. Not worth the trip.
On a 55-litre tank at 40mpg. The distance is straight-line rather than by road, so a real trip is longer than the one costed here.
