The rising price of oil and fuel duty as well as recent law changes is allowing some diesel users to reconsider the way they fuel vehicles.
According to the BBC, a number of people are brewing their own biofuel by converting old frying fat from local pubs and restaurants and using it to power their cars.
The news comes in the wake of recent developments that have pushed the cost of diesel over £1 per litre and changes to the law that make it legal for people to produce anything up to 2,500 litres of their own biodiesel.
Producers of conversion kits to allow the creation of fuel, which can cost from £700 upward, have recorded increased sales however one Aberdeen man has built his own using spare parts.
Dan Purkis, a consultant engineer, told the BBC's You and Yours this week: "No special tools were required and nothing was beyond the ability of a typical DIY enthusiast. Most of the parts were bought second hand or salvaged from scrap yards," he said.
Last year Norfolk council announced that it would begin to use old frying oil from local takeaway restaurants to fuel 35 of its vehicles, according to the BBC.
