For ages the cheapest was Sainsburies Alperton, and the Esso next door, at 1.29. But both have gone up to 1.30 or thereabouts. Asda at 1.28 is by far the cheapest, assuming it hasn't gone up since I last went on Weds. Other than Asda and Sainsburies, the Shell on the A40, the garage at Chiswick roundabout, and possibly the Murco garage by Acton Green, or the Esso near the North Circular Park Royal junction (next to the Brent recyling centre!) tend to have okay prices. Basically anywhere other than BP Horn Lane.
