In a recent video, Ms Houghton broke down why motorists should download this app to make big savings on petrol.

Her TikTok was captioned: “The biggest hack for saving money on petrol - have you tried this out? Let me know.”

The content creator shared: “I just found the biggest hack for saving money on petrol. I can’t believe I didn’t know about this app before, it’s honestly been life-changing.

“So, this app is called PetrolPrices and it does what it says on the tin. It tells you all the petrol prices at the petrol stations around you and compares them in numerical, chronological order.

“There is even an option to find the cheapest or nearest [petrol] stations on the map. There have been so many times when I need a cheap station.

“I end up going to either an Esso or Shell and end up spending god knows how much money on petrol.

“Not anymore. Especially in this time when petrol prices are so high, it has been a game-changer.”

In the comment section of the TikTok video, viewers shared their experiences of using the app to cut their car costs.

One commenter named Aimee said: “I downloaded this app the day. I passed my test, it's a lifesaver."

Those looking to download Petrol Prices can find it on the Apple App Store or Google Play store.
