Gasoil stockpiles in Amsterdam, Rotterdam and Antwerp rose 10% to 2.9 million tonnes over the past three months, helped from an increase in the number of imports into the area.
The fuel, which was made up of heating oil and diesel, was imported from countries including Canada, India, Latvia and Russia, Bloomberg reported.
Many of these cargoes were then shipped to the UK.
There is also a lack of fuel in the agriculture sector at the moment, which fuelled the increase of imports.
Petrol stockpiles also grew by 1.5% to more than 870,000 tonnes, delivered from Denmark, France, Latvia, Russia, Sweden and the UK.
However, naphtha stockpiles fell 30% to 56,000 tonnes and jet fuel storage also declined, dropping to its lowest level since 20 January 2011, at 680,000 tonnes.
