STA-BIL Diesel Formula prevents the formation of bacteria, sediment, and sludge in diesel fuel
STA-BIL offers a diesel formula fuel stabilizer that is specifically designed to address issues related to Ultra Low Sulfur Diesel fuels and new diesel engine technologies. This includes preventing the formation of bacteria, sediment, and sludge in diesel fuel.
The diesel formula STA-BIL fuel stabilizer contains high levels of detergents and lubricity agents. When used regularly, it helps remove sediments and fuel system deposits, in addition to lubricating critical fuel system components. This keeps your diesel engine running smoothly and prevents starting problems, poor engine performance, and reduced fuel economy.
The formation of bacteria, sediment, and sludge in diesel fuel can cause major issues for diesel engines. Untreated diesel fuel can begin to degrade in as little as one week, leading to contamination of the fuel load and subsequent engine problems. By preventing the formation of these substances, the diesel formula STA-BIL fuel stabilizer helps to maintain the performance and longevity of diesel engines.
In addition to its detergent and lubricity properties, the diesel formula STA-BIL fuel stabilizer also helps remove water from the diesel fuel. This is achieved through a process called demulsification, where water is broken down into small droplets and separated from the fuel. By eliminating water from the fuel, the diesel formula STA-BIL fuel stabilizer further protects diesel engines from corrosion and creates an unfavourable environment for the growth of fungi and algae.
Overall, the STA-BIL Diesel Formula is an effective solution for preventing the formation of bacteria, sediment, and sludge in diesel fuel. It helps maintain the performance and longevity of diesel engines by addressing issues related to Ultra Low Sulfur Diesel fuels and new diesel engine technologies. By using the diesel formula STA-BIL fuel stabilizer, diesel engine owners can ensure that their engines run smoothly and efficiently.

STA-BIL Diesel Formula can be used in all diesel fuels, including Ultra Low Sulfur Diesel and Bio-Diesel blends
STA-BIL offers a range of fuel stabilizers for different types of fuel. STA-BIL Diesel Formula is a special variant of the fuel stabilizer that is designed for diesel engines. It can be used in all diesel fuels, including Ultra Low Sulfur Diesel and Bio-Diesel blends.
The STA-BIL Diesel Formula is formulated to address issues related to modern diesel fuels, such as Ultra Low Sulfur Diesel, and new diesel engine technologies. Ultra Low Sulfur Diesel fuels are less stable than traditional diesel fuels due to their reduced sulfur content, which can lead to decreased lubrication and more engine problems. The STA-BIL Diesel Formula helps prevent sludge and sediment formation, corrosion, and lubricity issues commonly associated with these modern diesel fuels.
The STA-BIL Diesel Formula contains high levels of detergents and lubricity agents. When used regularly, it effectively removes sediments, fuel system deposits, and water from the fuel. By demulsifying water and allowing it to be separated and removed from the fuel, the STA-BIL Diesel Formula inhibits the growth of fungi and algae, which often thrive in untreated diesel. This treatment also helps protect against corrosion and keeps critical fuel system components lubricated, ensuring optimal engine performance.
The STA-BIL Diesel Formula is recommended for use at every fill-up to protect diesel engines from the aforementioned issues. It can also be used during storage to maintain diesel fuel freshness for up to 24 months. The recommended dosage is 30ml for every 38 litres of diesel fuel for everyday use, and 30ml for every 19 litres for storage.
