Google Maps blanks any UK Fuel Finder price it cannot confirm is current

Google's launch post promises motorists "a real-time look at petrol and diesel costs at nearby stations" ^[6]. The reporting rule under the feed is looser than that. After a station changes its pump price, Fuel Finder can carry the old figure for the whole reporting window the rules allow ^[7]. Any processing delay on Google's side comes on top of that.

Prices appear in Maps from 8 October 2026 ^[1]. Google's answer to the reporting gap, as dev.to describes it, is a check of its own. Google says it will independently verify the data, and a station whose price it cannot confirm as current stays on the map with no price attached ^[3]. I think blanking is the correct default for a comparison feature. A stale low price sends a driver to a forecourt that no longer charges it, while a blank pin costs them a glance at the next one.

The check can take a number away but cannot make a late station report sooner. To judge that a feed value is still current, Google needs some signal from outside the feed. Neither Google's post nor the dev.to account describes that signal, or how old a price must be before it is dropped.

That leaves three cases on the map. A station outside Fuel Finder has no feed price to show, and dev.to reports that some stations have not signed up while others are slow to update ^[13]. A late station that the check catches appears with no price ^[3]. A late station the check misses shows an old price as if it were current. Only the third case puts a wrong number in front of a driver, and how often it occurs depends on how well the check detects lateness.

A small error costs a driver little on one tank. According to the AA, 55 litres of diesel costs about £110 and the same volume of petrol about £96 ^[9]. The average diesel price has since fallen about 2p, a drop dev.to says made little difference to the cost of a fill-up ^[11]. On a 55-litre fill that 2p is worth about £1.10 ^[12]. A stale price out by the same 2p would misstate a full tank by that amount.

Apple Maps has no built-in equivalent, though third-party apps that connect to Apple's maps offer one ^[5].
