Petrol prices hit a record high last week, with an average of 121.76p being charged for a litre of unleaded fuel.
There's more to come, too. According to price monitor, Experian Catalist, we can expect further rises in January in the face of higher VAT and increased fuel duty. VAT is expected to add 2.5p to a litre, while the fuel duties will add a penny.
There is some good news, however. Those who use the black stuff still have a little way to go before the cost of diesel hits record levels - the current price of 125.73p per litre is still eight pence down on its record of July 2008.
Suggestions for the reasons behind the high prices include the recent cold snap causing disruption to deliveries, and the price of oil - about $90 per barrel is a record high for 2010.
According to the AA, motorists are having to pay an average of almost £6 more to fill an average tank compared with the start of the year.
