Waste oil to base oil: the sustainable approach
Collecting used oil and reprocessing it into a base oil product, a key component in producing brand-new lubricating oil, through a circular process.
Our operations in the UK undertake significant volumes of vehicle servicing, which commonly includes changing the engine oil. This activity generated 346,000 litres of used lubricating oil in FY2025.
Slicker collected the used oil and processed it at its state-of-the-art refinery, which recycles the used oil back into a base oil product—a key component in brand-new lubricating oil.
Other UK-based waste oil service providers predominantly generate Processed Fuel Oil (PFO) from their collected waste oil. This carbon-emitting fuel, used in the marine and energy markets, greatly affects the climate crisis; is still a very significant disposal route for waste oil for the UK automotive industry.
Through this sustainable process provided by Slicker, the oil we generate can be used again and again, preserving a valuable finite resource and greatly cutting our carbon footprint, this saved us c165 tonnes of CO2e.
