The cheapest diesel was 195.9p at Desborough Park, High Wycombe (HP12 3BE).
Across the UK, unleaded was up 1.7p over the same week, at 173.7p, which puts High Wycombe 1.9p below the national average.
"Drivers in High Wycombe paid 1.2p more for a litre of unleaded this week. On a 50-litre tank, that is £0.60 more than a week earlier. The gap between the cheapest and the dearest forecourt in High Wycombe is 6.0p, so where you fill up still matters more than when." said Jacky A., editor of fuelpricetoday.co.uk.

How the figures are computed
Each average is the mean of the prices changed in the last 7 days at the filling stations of High Wycombe, motorway services left out and prices more than 25p from the day's median discarded. The cheapest and most expensive stations are judged against the stations within 10 km, so that a typing error cannot top the list. The week runs from Monday to Sunday. Details on how this site works.
