A content creator has taken to TikTok to reveal the best day of the week to fill up on petrol, and it may surprise you.
The financial guru, who goes by the name “NDA” online, has amassed 572.6k TikTok followers and has earned 4.6 million likes on his account.
In a recent video, the money-saving expert urged Brits to fill up their tanks on Monday to secure the cheapest rates.
He said: "According to the Automobile Club Association study, Monday is the best day of the week for fuel prices."
Prices are at their lowest on Monday as they “fluctuate throughout the week,” said the content creator.
The influencer also claimed that filling up in the middle of the day is more expensive, especially on a hot day.
He added: "Plus, you should fill up in the morning since the volume or diesel varies depending on the temperature outside.

"When the weather is hotter the fuel expands and takes up more space inside the tank.
"So one litre of fuel is equivalent to less than one litre when you're refilling inside of a high temperature tank. So, you're basically throwing money away at the pump.”
The finance expert advises filling up your tank in the early morning or late evening.
However, Andrew Marshall, marketing and partnerships manager at Carmoney said the day of the week drivers fill up on is unlikely to make any noticeable difference to their bill.
Speaking to the Express, he said: "The fluctuations in fuel prices over a weekly period will be very minimal, and re-fuelling on a Monday compared to a Wednesday will probably not change your fuel bill by a noticeable amount."
According to Andrew, the science behind filling up at cooler times of the day is correct.
He said: "With regards to the expanding fuel tip, this holds water as both petrol and diesel expand in hot weather and would take up more space in the tank.
"Topping up when the temperature is lower would give you the most of your tank’s capacity, though the difference would be slight."
However, he did share that the best way to save on fuel is to “keep track of local stations’ prices and go where the prices are lowest.”
Another fuel hack to save money claims drivers can save up to 20 percent on their fuel when driving at speed.
The driving test experts at TikTok account Driving Test Success claimed Britons will "use up less fuel" by rolling their windows up over certain speeds - even during a heatwave.
Drag caused by keeping the windows open wastes fuel.
At higher speeds, it wastes more fuel than having the air conditioning on.
