In terms of its benefits, at least in Canada, it saves me a bunch of dough on gas. Highly recommended.
Though I like the French approach where gas prices are all on a government website without needing to depend on crowd-sourcing: https://www.prix-carburants.gouv.fr/
I’m more worried about a navigation app spying on me.
There’s about a 13% difference between the cheapest and most expensive at the moment.
Or forget it all and go straight to Costco.
No way, I value my time tyvm.
At locations near me, I swear one spouse goes in to shop for 2h while the other waits in line for gas for as much of that 2h as they can.
For various personal reasons I haven't been driving a ton lately, so I'll pick a more typical month.
My direct discounts were $17.88 in that month on gasoline that was priced at $269.49, at a cost of $9.99, for a total savings of $7.89.
Plus whatever extra I might have paid if I didn't use GasBuddy at all to help with planning to buy gas where the price at the pump is cheapest (which anyone can do without a subscription or installing an app). The potential savings gained by being very selective of where I buy gas, using information provided by GasBuddy, is impossible for me to tabulate.
If I had to guess, then I would guess that being selective saves me an average of around 10%. So, about $27 in my example month.
(I do not participate in any of GasBuddy's drive-tracking programs, and it only knows my location when the app is open. Drive tracking is a thing they offer people to opt into (for "free") but I could see the writing on the wall with that, vis-a-vis this Allstate incident.)
