The RAC said the average price of a litre of the fuel at UK forecourts on Thursday was 134.06p.
That is the cheapest price since July 2021, when it was 133.9p.
The RAC said it was “disappointing” the price drop has not been even steeper, given cuts to oil prices.
It believes wholesale costs being paid by retailers indicate the average price of both petrol and diesel should be 4p per litre lower.
That would bring the average price of a litre of petrol down to 130p, and diesel down to 136p.
