Last month’s diesel sales set a new record of 2.501 billion litres, up 144 million litres or 6.1% compared to October (2.357bn ltrs) and 64 million litres higher than in November 2013 (2.437bn ltrs).

Diesel pump prices fell from 128p a litre at the start of November 2014 to 126p by the end. This compares with an average of 137.8p in November 2013.

Department for Transport statistics reveal that, in the third quarter of this year, car traffic rose 0.6% compared to the previous quarter. However, HGV traffic was up 1.1% and light goods vehicles were up 2.9%. Car and HGV activity remains below late 2009 levels, while LGV levels are 12.6% higher than in the third quarter of 2009.

The number of petrol cars fell by only 1.5% (288,500) in 2013 compared to 2012, while the diesel car population increased by more than 7% (679,000).

“Once again, the official statistics illustrate the trauma of cripplingly high pump prices over recent years. In 2012, you could see the petrol consumption rise and fall in line with prices. Now consumption is struggling to get out of the rut created by drivers and families being forced long-term to adopt fuel-saving travel patterns to make ends meet,” said Edmund King, the AA’s president.

“It suggests that the savings from lower pump prices are being used to balance the books of family expenditure rather than increasing mileages. This points to the likelihood that much of the spare cash will find its way back to the high street.

“Whether that continues as pump prices fall further, we shall see. It took the UK motorist two years to adapt to dealing with price surges on the forecourt and it will take a long time to ease the fuel-saving habit.”
