Diesel Generator Fuel Tank FAQs

  • How much diesel does a generator use?

    The answer to how much diesel fuel a generator uses will vary according to how much power the diesel generator produces, what fraction of load it is being run at, and how long it is going to be run for. There are however assumptions that can be made.

    The greater the power of a generator (usually measured in kW or kVA), the more fuel it will use per unit of time. The higher the load it is being run at, the great its fuel consumption will be. Naturally, the longer it will be run for, the more fuel it will use.

    For accurate information regarding your specific generator’s fuel consumption at various loads, please contact your manufacturer.

  • How long does diesel last?

    Diesel fuel has a shelf-life. The consensus is that it can only be stored on average for between 6 and 12 months. The actual figure may be longer under perfect conditions or shorter if precautions are not taken. The main factors affecting diesel shelf-life are water, microbes, and oxidation.

    There are steps you can take to help reduce the effect of these factors:

    – Keep your tank covered

    – Keep your tank cool

    – Keep your tank topped up

    – Use biocides

    – Keep your tank clean

    – Treat your diesel fuel with appropriate additives

    – Keep your tank maintained

    When degraded diesel is used, it can corrode the insides of diesel storage tanks, engines, and generators. It can also block diesel injectors and filters. So by following these steps, you can help to maximise the life of your diesel fuel, and also your tanks, engines, and generators!

  • How far does a generator need to be from a house?

    It is a requirement generator fuel tanks be at least 6 metres (19 ½ ft) metres away from any boundaries, houses, or buildings because generator fuel tanks are more than capable of carrying over 3,500 litres of flammable fuel. This is for the protection of life, property, and the environment.

    Another standard of safety is that we ask our clients to remember to position their generator fuel tank so that the engine exhaust is directed away from the windows and doors of the house. Choosing a low-risk location (i.e. a place with limited water) is vital in not only keeping the environment safe but also keeping yourself safe from any accidents
