Store diesel fuel in a clean, dry place
Diesel fuel has a lifespan of six to twelve months on average, but it can last longer under optimal storage circumstances. The quality of diesel fuel begins to deteriorate after six months, and it can become contaminated and degrade within 28 days of storage. To increase the lifespan of diesel fuel, it is critical to avoid contaminating it.
One way to avoid contamination is to store diesel fuel in a clean, dry place. Keeping the fuel dry is essential because water exposure is a significant cause of fuel degradation. A dirty tank might taint the fuel and reduce its shelf life, so it is important to store diesel fuel in a clean tank or container. In addition, if the gasoline has been exposed to water, it is best to engage a diesel bug removal business to properly remove the water.
It is also important to keep the fuel cool, as diesel fuel should ideally be stored at around 70°F. If the fuel gets too cold, it will gel, and if it gets too hot, it will degrade quickly.

Use a fuel stabilizer or biocide
Diesel fuel has a relatively short shelf life and can start to degrade within 28 days of storage. To extend the life of diesel fuel, you can use a fuel stabilizer or biocide.
A fuel stabilizer or biocide is a product that is added to the fuel to prevent degradation and maintain its quality over time. Diesel fuel is susceptible to microbial contamination, which can lead to the growth of bacteria and fungi. This contamination can result in the formation of biomass, which contributes to problems such as accelerated tank corrosion.
To combat microbial contamination, a diesel fuel biocide can be used. A biocide is a product that kills microbes, including bacteria and fungi. Examples of diesel fuel biocides include Biobor JF, Bio Kleen Diesel Fuel Biocide, and Bellicide. These products are effective in both diesel fuel and water, making them suitable for use in fuel tanks. When using a biocide, it is important to follow the recommended concentration and properly mix it with the fuel.
In addition to biocides, fuel stabilizers can also be used to extend the life of diesel fuel. Fuel stabilizers work by inhibiting the oxidation of the fuel, which slows down the degradation process. They can also help to dissolve water in the fuel, preventing the growth of microbes. Some fuel stabilizers may also contain additional additives, such as cetane improvers, lubricity improvers, and detergents, which can enhance fuel performance and protect engine components.
By using a fuel stabilizer or biocide, you can effectively extend the life of diesel fuel and prevent issues related to microbial contamination. These products are especially useful for diesel engines that are subject to extended periods of non-use or stored in warm and humid environments, as these conditions can accelerate fuel degradation and the growth of microbes.

Maintain proper tyre pressure
Maintaining proper tyre pressure is crucial for several reasons. Firstly, it helps extend the life of your tyres, as underinflated tyres can lead to increased wear and tear and even blowouts. Secondly, it improves vehicle safety by ensuring optimal braking distances, grip, handling, and cornering capabilities. Finally, it maintains fuel efficiency, saving you money and reducing fuel consumption.
To check your tyre pressure, locate the recommended PSI (pounds per square inch) or BAR pressure in your vehicle's manual, on a placard sticker usually found on the driver's door frame, or by using a tyre pressure gauge. Tyre pressure gauges can be analogue or digital and are placed on the valve stem to provide a reading. Compare this reading to the recommended pressure, and if it is low, add air using an air compressor; if high, release air.
It is recommended to check your tyre pressure regularly, at least once a month, and before long journeys. Tyre pressures may also need to be adjusted according to the ambient temperature, as air expands when heated and contracts when cooled. Therefore, it is best to check the pressure in the morning before the tyres have been used and are still cold. Additionally, ensure that you follow the manufacturer's recommended tyre pressure for your vehicle's specific make and model, taking into account factors such as total weight, size, and towing capacity.
By maintaining proper tyre pressure, you can improve the overall performance, safety, and fuel efficiency of your vehicle, making it a crucial aspect of diesel engine maintenance.
