The figure has been calculated by taking the highest and lowest unleaded petrol prices nationally by town for October and assuming three weekly fill-ups and 15-gallon fuel tanks. Even though the price of fuel fell fractionally across all grades - 0.55p a litre/2.5p a gallon - last month, PHH says fleets must urge drivers to watch pump prices. The latest report shows pump prices vary by as much as 4.2p a litre/19p a gallon across all fuel grades.
Highest and lowest fuel prices: diesel - lowest, Glasgow 62.62p a litre/284.67p a gallon; highest, Aberystwyth 66.13p/300.62p. Unleaded - lowest, Bradford 62.76p/285.3p; highest, Aberystwyth 67.21p/305.53p. Four star - lowest, Halifax 66.86p/303.94p; highest, Cambridge 71.42p/324.67p.
