The TankSponge Eco is an environmentally-friendly tool designed to help prevent the build-up of water and sludge within your fuel tank, and maintain the quality and efficiency of your fuel.

The device consists of a hinged cage designed to hold replaceable TankSponge Eco inserts, each of which will soak up contaminated water from the bottom of your tank, whilst not soaking up any of the fuel, be that Kerosene, Gas Oil, or DERV.

The TankSponge Eco has also been designed with the environment in mind, with the specially moulded cage being made from 100% recycled plastic and being packaged in 100% recycled cardboard.

Very quick delivery. Ordered 27 March delivered 29 March. In this “online” era I am pleased to be able to phone order and speak to Kim. Extremely sociable and helpful. I was out so unfortunately did not meet driver. Thank you all.

They price- matched and were slightly cheaper than competitors. As requested, their driver called when on way with delivery next day. Also, unlike others, they don’t demand payment up-front for ‘promise’ of a delivery but invoice after delivery.
Altogether excellent.

We have been customers of Southern Fuels for many years, they are always super helpful, especially when I run out of oil! Friendly staff and drivers. Can’t fault them for service and pricing. We will be staying with them. Thank you Southern Fuels.
