The average price of petrol fell slightly in February, marking eight consecutive months of falls, data shows.
Motorists have now enjoyed eight months of falling unleaded prices from the beginning of July 2015, when the average price of a litre was 117p a litre.
At the end of February, the average price of petrol at forecourts was 101.93p - a drop of 15p and a saving of £8.25 on filling up an average 55-litre family car, according to RAC Fuel Watch data.
Diesel rose by an average of one pence per litre at the pumps in February - up to 101.18ppl - which reflected the 2.5ppl increase in the wholesale price.
RAC fuel spokesman Simon Williams said: "Forecourt prices of both petrol and diesel have remained remarkably stable in February despite the pound losing 3% of its value against the dollar and talk of an oil production cut.
"Motorists are still benefiting from low prices at the pumps, with the supermarkets having held their petrol prices under £1 a litre, thanks to a depressed wholesale price."
