Riserva: Fuel, Petrol Prices

How old is that price?

Riserva is an independent app. It is not a government service and does not represent any government entity.

Station operators are required by law to file their fuel prices with the government. Riserva shows those prices and, next to each one, when it was filed: "2 hours ago", "yesterday", "4 days ago". So you know which ones to trust before you drive across town to save three cents.

Four countries, one app
48,283 stations across Italy, Spain, France and Portugal. Riserva works out which country you are in and switches on its own when you cross the border, or you pick one in Settings. The stations you save sit in one list, whatever the country.

In the car, with Android Auto
The car screen lists the stations near you with price, age and distance, and one tap starts navigation. When recent prices exist, Riserva leaves the old ones out: a three-week-old price does not save you money, it sends you the wrong way.

What the fill-up really costs
Riserva ranks stations by what a tank actually costs you, the drive there included. The pump that is two cents cheaper fifteen kilometres away is not a saving, and a list sorted by price alone cannot tell you that.

Sign says something else? Fix it
Report the right price in two taps, or flag a station that has closed. A correction goes live only once several independent drivers report the same price, so no single person can move it.

Along your route, not just nearby
Driving three hundred kilometres? Riserva finds the cheapest stations along the way and shows how far off the route each one is and where it falls in your journey.

Every fuel, named the way the pump names it
Petrol, diesel, LPG, CNG, HVO, LNG, E10 and E85, with premium products under the names you see on the pump: V-Power, Supreme Diesel, HVOlution. A price per kilogram is never compared with a price per cubic metre.
