The combined effects of adding FAME (Fatty Acid Methyl Esters) and reducing sulphur have changed the characteristics of diesel fuel. The fuel supply chain is adapting to deal with the consequences in storage, from distribution to storage and right through to vehicles.
Avoiding water is much more difficult now as FAME, being hygroscopic, attracts it. With more water comes increased incidence of injector problems, corrosion and lubricity issues. Then there is, of course, microbial contamination aka ‘diesel bug’.
