A new sampling and testing protocol for red diesel is being developed following widespread problems with blocked filters on tractors and other farm machinery last year.
NFU Scotland (NFUS) transport adviser Jamie Smart said the new protocol was being developed at the request of a specialist taskforce at the British Standards Institution (BSI) established to investigate problems associated with the biofuel levels in red diesel.
“This means that in the event of any issues this winter we can be ready to gather further evidence of what is causing filter blocking problems and where exactly the fuel is coming from,” said Mr Smart.
He said investigations had found no clear cause of the filter blocking issues and NFUS and its counterparts in England would continue lobbying the BSI to ensure fuel specifications are fit for purpose in the agricultural sector.
He advised farmers to take steps to reduce the likelihood of similar fuel problems this year.
This includes not storing fuel for longer than six months, keeping storage tanks under cover to minimise the extremes of temperature and to use the correct grade of diesel depending on the time of year.
“If possible, fit a filter between your storage tank and the supply nozzle as these can help catch any large particles and dampness before they enter the tractor tank,” added Mr Smart.
“And finally, if you do encounter a problem which you suspect may be caused by contaminated fuel, contact your NFU Scotland regional manager for advice.”
