C H Jones, which operates the Keyfuels and Diesel Direct fuel cards, has published a new Diesel Driver Site Directory, providing details of more than 1,500 sites including 28 new entries. Business development manager Jason Hodge said this made the network - throughout which cardholders can draw diesel at fixed prices - the largest of its kind in the UK.

Hodge said that during the first half of this year the cost of filling up at general retail pumps increased significantly, compared to using commercial or bunkered diesel. 'This is good news for all users of the Keyfuels bunkering system, who can enjoy access to diesel sites across the country at competitive prices,' he said.
