It could cost £100 to fill your car up with petrol from today, 9 June.
On Tuesday, 7 June, the price of petrol increased by 2.2p, while the average price for a litre is now 180.7p, according to Experian Catalist.
If the price increased by the same amount on Wednesday, this will mean that the cost of a full 55-litre tank will be more than £100 for the first time, reports WalesOnline.
The new figures for Wednesday will be released later today.
If a similar increase has occurred, it could cost an average, family-sized 55-litre car more around £100 for a full tank of petrol.
James Andrews, personal finance expert at Money.co.uk, said: "Consumers are being hit from all sides but nowhere is this as obvious than at the pumps. Petrol prices have surged 36.5% in a year, rising by four times the rate of inflation.
"It's a pace that is obliterating people's disposable income. It both eclipses and exacerbates the wider cost of living crisis, which saw CPI hit 9% in April – a pace that was already causing sleepless nights over at the Bank of England."
Simon Williams, a spokesperson for the RAC, said to Sky News: "The cost of filling a 55-litre family car with petrol has now topped £98 for the first time in history.
"With analysts predicting that oil will average $135 a barrel for the rest of this year drivers need to brace themselves for average fuel prices rocketing to £2 a litre which would mean a fill-up would rise to an unbelievable £110.
"We strongly urge the Government to take drastic action to help soften the impact for drivers from these never-before-seen pump prices."
As the prices for petrol soar in Wales, care boss worker Emma, who runs Vale Senior Care in Denbigh, says staff have been coming into work crying because they couldn't afford the fuel in the car.
While her 10 members of staff usually drive into work, due to the circumstances, she says she's received a local grant to receive road-legal electric scooter and bikes, as a short term solution.
She said: "Because we work in a rural area, I've been paying bonuses in order to retain staff.
"I can imagine a couple will think 'I can't work in the domiciliary sector anymore'. Even though I pay the maximum in fuel, it's just not going to work.
"It could work in seaside towns and small areas, but in Denbigh the roads are narrow. It could work in Llandudno on the flat, Rhyl Colwyn Bay, but in Denbigh it's limited.
"You need to be quite fit and not everyone is confident."
