• Shell has replied to concerns expressed by the Freight Transport Association and says it is not selling Advanced Diesel XL diesel to hauliers.
According to the FTA, this diesel— which does not conform to British standards for temperate climates—has been sold from UK filling stations and it is concerned it may still be available to CV operators. The FTA is also concerned that this fuel, which has a relatively low density and viscosity, causes higher emissions and higher fuel consumption.
This claim is supported by independent fuel expert Dr Jim Laxton of ITS Testing Services, who says tests suggest an 8% reduction in fuel economy. The FTA is also concerned that Advanced Diesel
XL could damage the fuel injection pumps of electronically controlled engines.
Shell technical manager Cathryn Hickey says there is no evidence to suggest that the fuel has damaged fuel injection pumps.
Shell obtained a derogation from the Government in 1996 to make and supply the diesel to London Transport buses. Between November 1998 and February 1999 the company also sold it from 140 retail filling stations in the London area as a "test market exercise".
But Hickey refutes the FTA's concern that Advanced Diesel XL may remain in commercial distribution. "We are only supplying Advanced Diesel XL to one customer, bus operator Arrive she says. "It is not being sold to anyone else."
All retail stocks of Advanced Diesel XL have now been replaced by Shell Pura Diesel which meets British Standard EN590, she adds.
