How long does diesel last in a generator?


The truth is, diesel, like all fuel, begins to degrade as it is exposed to external factors. It depends on those external factors but if you’re using common on-road diesel and you’re investing in proper maintenance, you should get a solid 12-18 months out of it before you would expect to start seeing issues from its usage. To get the best advice based on your specific environment and usage, rely on professional generator servicing in Brisbane. Sometimes, in more volatile environments, the diesel in your industrial generator can last 6-12 months. Generally, common knowledge dictates that the way to prolong the quality of stored diesel fuel is by keeping it cool and out of the sun, treating it with stabilizers, and maintaining it properly. You can easily tell that your fuel is experiencing erosion if the filters are clogged and there is rust on the fuel cap. The main thing that has a substantial effect on eroding your fuel is moisture.

Fuel contamination happens when the diesel in your generator or otherwise is exposed to an environment element that will accelerate the natural processes of ageing and quickly attack its quality. All petroleum fuel, whether gasoline or diesel, will react this way to the environment like your fence planters. Moisture can cause fuel contamination and that’s really the main matter at hand. Diesel fuel contamination is the main cause of premature shutdowns or start-up failure in industrial generator models. The longer your fuel sits in the tank, or is stored on the property, the higher the probability of some moisture linked fault.

The natural response is to either store diesel on your property or make sure you are replacing your fuel as soon as its levels are low. Either way, diesel that sits for a long time in your generator, or on your property is vulnerable to environmental erosion and there’s nothing you can do to stop that. The thing you do have control over, however, is how well you keep up with regular maintenance of your industrial generator and the fuel in it. This will be an effective way to keep a close eye on how your diesel is ageing and what you need to do about it to avoid any emergency situations where your unit fails to start. If you invest in regular maintenance, you are already going a long way towards prolonging the shelf life and quality of your diesel fuel.

How to maintain the diesel in your industrial generator

The following steps are not full proof because diesel will experience contamination and be spoiled by the environment in one way or another anyway. Maintenance is only a way to prolong potential damage that has the risk to completely stop your generator from working. Use your local generator servicing in Brisbane as a matter of urgency. These are a few steps that can ensure that your fuel stays clean and uncontaminated.

  • Inspecting the tank for water build up

Check the fuel tank for pooled water in the system and especially after rain. Again, we’d like to emphasise that water is our enemy and if it develops in your industrial generator, it can be disastrous. You can maintain the fuel tank and the diesel in it by checking it regularly to remove pooled water on top of the tank and more often if you live in humid or rainy parts.

  • Place your generator in cool conditions

Generators that are installed in cooler areas are less susceptible to water and oxidization development. You can achieve this by considering an underground generator installation or by providing structures and ventilation systems around your unit to keep it out of the sun and cool. Who knows who might end up finding crystals in your backyard.

  • Regularly treat your diesel

We’re not talking about a pampering session, but this achieves the same effect. There are products you can buy that treat the fuel. Check your manufacturer instructions or speak to a professional technician about what kind to buy but diesel treatments will add enhancing qualities like antioxidants. These will maintain and reinvigorate, the quality of the diesel fuel by stabilizing it and preventing a chemical breakdown.

  • Completely drain and clean the tank every ten years

This is a long-term solution but it’s an indication of how long your diesel can last if you look after it. It’ll need a complete cleanse every decade or so to not only maintain the future life of diesel addition, but also the lifespan of the tank. It’ll empty out the tank of any impurities and give the tank a completely fresh start.
