But how accurate was the data on those older apps?

Petrolprices.com (for example) seems to have been built on user-reported data rather than petrol-station reported data, and it's easy to find fairly recent criticisms of the whole thing being inaccurate. And an inaccurate comparison site is fairly useless IMHO.

I lived in the UK until 2021 and I must admit I'd never heard of them. Whereas here in WA everyone uses fuelprices. There are probably other factors involved here as well, as we have a weird weekly or biweekly price cycle (though I think this has ended somewhat in the last two years) where every second Tuesday fuel was dirt cheap as they were trying to clear down the tanks ahead of the next delivery.

Is the 'new part' not that the vendors are being forced to actually publish comparison data rather than rely on third parties to gather it?

Other than a time lag (and petrol prices don't generally change often enough to matter IME), I can't say I ever noticed any of them being that inaccurate.

myAutomate (the owners of Petrolprices.com) talk about having "over 60 years combined expertise in the fuel industry", so I suppose I'd be surprised if it's all crowdsourced data - they've probably made arrangements with at least the big players, in which case the forced publication is much of a muchness?
