Where does waste red diesel come from at marinas and boatyards?

In brief

Boat tanks with water, diesel bug and phase-separated petrol, and fuel drained during engine work and winterisation. Call 07950 582635 or send an enquiry.

Common problems with red diesel at marinas

Water in red diesel: water is where most diesel problems start. Diesel bug in red diesel: the microbes form slime and sludge that block filters and injectors, and produce acids that corrode tanks and fuel systems. Old red diesel: old diesel forms gums and acids, mostly from its biodiesel content, which block filters and injectors.

Containers at marinas

Drums, cans, small tanks and fuel berth tanks.
