GREENERGY has developed an ultra low sulphur petrol which will be available on forecourts from mid-June. Citypetrol, which follows on from Greenergy's successful ultra low sulphur Citydiesel, will be available initially from 40 Sainsbury's sites within the M25 but will be rolled out across the UK over the next few months.

The petrol will initially cost about 1.5p per litre more than unleaded, but Greenergy will be lobbying the Government for a reduction on duty. Car manufacturers have long called for ultra low sulphur petrol to be made widely available, but the major oil companies are reluctant to go down that route. But Greenergy director of branding Steve Chandler said drivers were prepared to pay a little more for a genuinely clean fuel.

'When we launched Citydiesel everyone said it wouldn't work, but sales are 50/50 with normal DERV now where both are available and where solus Citydiesel is available we have not seen any market share drop off,' he said. 'Market research tells us that if people know a fuel is genuinely going to do something good for the environment they will pay extra for it - but not more than 1.5 to 2p.'
