The average cost of filling an average family car with petrol could exceed £100 for the first time on Wednesday.
Data firm, Experian Catalist, announced a litre of petrol cost on average 180.7p earlier today.
This is an increase of 2.2p compared to the previous day.
The RAC confirmed the jump was the largest daily increase in over 17 years.

An increase set for Wednesday will raise the average cost of filling a 55-litre family car to in excess of £100 for the first time ever.
Forecourts across the UK are already selling petrol above £2 per litre, including a BP garage on the A1 near Sunderland which is charging 202.9p per litre to customers filling up.
Diesel prices have also surged this week with prices reaching record highs of 186.6p on Tuesday, up 1.4p from Monday.
The average cost for the day will be published on Thursday morning.
RAC fuel spokesman Simon Williams said: “A full tank of unleaded has now shot up to £99.40, moving us ever closer to the milestone £100 petrol fill-up – an unfortunate landmark we may reach as soon as today.
“Asda hiked its average petrol price nearly 5p a litre in a single day, which is unheard of.
“These are unprecedented times in terms of the accelerating cost of forecourt fuel.”
He added that “we are still some way from the peak” as it will take several days for an unexpected fall in wholesale costs on Tuesday to be reflected in pump prices.
Rises follow announcements by the Chancellor Rishi Sunak, who announced he would help struggling families cope with a £650 cost-of-living payment, issued in two instalments.
