This article reviews a recent survey of nearly 300 samples, which reveals huge variations in the sulphur content of derv (diesel fuel) worldwide. The results were contained in the 11th winter diesel fuel quality survey from the Paramins Division of Exxon Chemicals, which markets diesel additives. The survey's tests were conducted on 286 fuel samples collected between December 1994 and February 1995. Parameters investigated by the survey included: (1) the fuel's cold flow performance, i.e. its ability to withstand the onset of waxing in cold weather, which is the most important parameter for most operators during winter, showing a cold filter plugging point between -15 and -23 degrees C in the UK; (2) the sulphur content of diesel, which ranged between 0.078% and 0.195% in the UK; (3) derv density, which ranged between 834 and 852 kg/cu.m in the UK; and (4) cetane value, which ranged between 46.3 (well below the minimum requirement of 49) and 53.9 in the UK. Internationally, sulphur contents ranged from very low in Scandinavia and Switzerland to nearly 0.8% in Turkey and the North American Mid West, high enough to harm the environment, and high enough to damage a diesel engine without extra maintenance. Throughout Europe, only two of the fuel samples had cetane value less than the UK's minimum value of 46.3.
