Three tips on fuel to get good performance from your backup diesel generator

July 06, 2022
Diesel generators are one of the best backup power solutions to protect the normal production and operation of a business in case of emergency. If a business loses power, a backup diesel generator will provide continuous power support. For those construction sites in the field, standby diesel generators allow the site to always have a continuous and stable supply of reliable power to ensure the smooth running of the project.
Standby diesel generators are often very reliable and can easily be left dormant for long periods of time between uses. However, this is not the case with the fuel used in generators. This article will cover three useful tips to get the best performance out of your standby diesel generator while avoiding the kinds of problems that can cause a generator to fail at the worst possible time.
1. Store diesel generator fuel properly
Diesel fuel must be stored properly to avoid unnecessary evaporation and to prevent debris and airborne substances from contaminating it. Impurities in the fuel can quickly clog the generator's filter. In turn, this will restrict the flow of diesel fuel - causing the generator's motor and other components to overheat. Eventually, "dirty" fuel can cause your generator to stop running altogether.
Water represents another problematic substance that can wreak havoc on the engine in your generator. If water builds up in the fuel source, it will often cause your generator to experience problems such as hard starting and rough running. It can also promote rusting inside the generator.
Internal rust increases the amount of particulate matter flowing through the generator, which speeds up general wear and tear. If severe enough, it can also cause some components to fail completely. Fortunately, you can prevent physical and water contamination by storing your fuel properly.
2. Use fuel stabilizers
No matter how well stored, there is no escaping the fact that diesel fuel is a volatile petroleum derivative. Over time, it will continue to undergo chemical changes. The most common change is the process of phase separation. This involves the separation of the different components that make up diesel fuel into different layers.
The more the diesel fuel breaks down, the more problems it creates when you put it into a generator. Fortunately, you can extend the life of your stored gas by using fuel stabilizers. As the name implies, these substances improve chemical stability - ensuring that your gas stays fresh for at least a few months.
3. Changing fuels
To be truly prepared for a power outage, your fuel tank needs to be full of diesel fuel. In fact, many people keep four or five tanks on hand for safety reasons. Be sure to label each tank with the date you filled it. This will allow you to monitor the age of the diesel fuel so that it stays within the specified life of the particular fuel stabilizer.
To make sure it doesn't go to waste, always use the oldest diesel fuel first. If the diesel fuel is nearing its limit, use it up as soon as possible and refill the tank. This way, you will still get the latest and cleanest diesel fuel from each tank.
