CITY diesel distributor Greenergy has hit out at a BMW document which apparently advises fleet operators to avoid using its ultra low sulphur diesel. In a circular issued by BMW's technical services department in Germany, Greenergy's City Diesel is omitted from a list of low sulphur diesel fuels which the manufacturer recommends.

The list includes fuels from most of Europe's major suppliers, which have additives designed to improve their lubricity and avoid the additional wear on fuel injection pumps associated with some low sulphur fuels. The BMW circular advises customers only to use fuels listed and insist that their suppliers provide diesel fuel with the additives until the oil industry agrees a standardised lubricity.

Greenergy managing director Andrew Owens said City Diesel had the highest lubricity of any low sulphur diesel fuel on the UK market and was the only fuel whose lubricity was guaranteed to meet the Association of European Automobile Constructors' standards.
