GUIDE
BP’s advice on long term storage of diesel.
WASP isn’t the only company advising that modern diesel has what can best be described as a ‘shelf life’. Even the fuel companies supplying the diesel agree. BP has issued a document detailing best practice for the long term storage of diesel.
BP notes that:
- Under normal storage conditions diesel fuel can be expected to stay in a useable condition for:
- 12 months or longer at an ambient of 20ºC.
- 6-12 months at an ambient temperature higher than 30ºC.
- The ageing process can be accelerated by:
- The presence of water. Water allows the growth of fungus and bacteria. These produce natural by-products such as organic acids which make the fuel unstable.
- Exposure to dust and dirt which contain trace elements that can destabilise the fuel such as copper and zinc.
- Fuel composition. Some components in diesel fuel (especially biodiesel) naturally age quickly.

ATEX and fuel polishing
In mid 2015, diesel was reclassified. As it has a flashpoint of 55 deg C and above, whereas the lower limit for hazardous material has been moved from 55 deg C to 60 deg C, diesel must now be considered to be a hazardous material. This means clients may wish to consider ATEX in future installations.
