Cost of filling a family diesel car breaks £100 mark - RAC statement and data
As the average price of petrol has risen 20p since the start of the Iran conflict, RAC head of policy Simon Williams said:
"Diesel has now climbed to an average of 182.77p a litre which means the cost of filling a typical 55-litre family car has breached £100 (£100.52) for the first time since early December 2022. With petrol now at 152.83p, a full tank is setting drivers back £84. Unleaded has increased 20p a litre since the start of the conflict and diesel by 40p, making a full tank £11 and £22 more expensive respectively.
"RAC analysis of wholesale fuel data points towards the price of petrol potentially stabilising if the cost of oil doesn't increase further, although diesel still looks likely to rise."
