“The more often that fuel is moved around Europe and imported into the UK, then the more likelihood of an


increased bio-content in the UK diesel supply”


months, and this advice is echoed by various other sources.


Vehicle manufacturers and suppliers now specify the expected fuel quality and/or required fuel additives in the vehicle manuals, and are increasingly prickly about warranty claims made for a vehicle run on non-approved fuel, especially if it involves the exhaust after treatment.


Fuel additives and conditioners are available in different forms from a number of companies. They set out to do several jobs, either as problem- specific individual fuel treatments or as broad- spectrum products.


Typically, additives can do one or more of the following:


• Raise the fuel cetane number, usually to a minimum of 51


• Increase fuel lubricity – the ‘oilyness’ of the product


• Dissolve and remove deposits from the injection system components


• Counter fuel oxidation during storage


• Encourage water to come out of suspension in the fuel so existing water traps can remove it


• Lower the temperature at which waxing starts to occur


• Counter any increase in microbiological activity within the fuel


The use of such additives is now commonplace in the agricultural and construction sectors and, whether you regard them as positive benefits, necessary evils or insurance policies, they are worth a closer look.
