With the current climate, many industries are operating at a much lower capacity than normal, with some not operating at all. As a result, there will be a large stock of fuel for machinery, vehicles and other equipment that is not being used at the same rate as it previously was. This combined with the very low price of oil means many companies will be looking to store large amounts of fuel-ready for when the lockdown lifts and they can go back to work. Unfortunately, storing fuel for long periods of time can cause it to go off or be less effective than when it was first stored, so it is important to consider the ways in which it can be preserved and protected.
Diesel is one of the most commonly used fuels within many industries. Damage to diesel can occur during storage when it begins to oxidise. The fuel reacts with the air which can cause a sediment sticky gum residue to form. This can not only clog up filters and engines but can affect the diesel’s ignition quality and lead to a buildup of carbon and soot. Diesel is also prone to microbial growth – bacteria and fungus can build up in a tank and have a detrimental effect on the fuel and equipment it is used in.
The means of prevention for these problems is to use a diesel additive like our Fuel Store Plus. This will stabilize the fuel, preventing oxidation and microbial growth and allow it to be stored for longer periods of time. The fuel degrading process can be slowed further by storing the diesel at temperatures below 20°C and keeping the tank out of direct sunlight.
Like diesel fuels, petrol can suffer from oxidation when stored for a long time, along with evaporation. This causes a gum residue to form and if used, old fuel can cause an engine to be much less efficient. This residue will harm the engine if there is a significant amount of build up within the tank.
Using a fuel stabilizer gives petrol sitting in a container a protective layer by bonding with it, preventing evaporation and therefore extending the shelf life of this fuel.
Reviving Old Fuel
Sometimes preserving fuel may not be possible, or you may have some old fuel that could still be useful. In some cases this fuel may still be used with the help of a fuel reviver. This fuel additive can return the oxidation stability of out-of-spec distillate fuels to within acceptable limits, allowing it to still be useful.
