STA-BIL contains a fuel injector cleaner to improve engine performance
STA-BIL is a fuel stabilizer that can be used on gasoline and diesel engines, including two-cycle and four-cycle engines, as well as marine and agricultural equipment. It is designed to keep fuel fresh and stabilized for up to 24 months, although fuel stored for more than 12 months may experience some loss of volatility. STA-BIL is safe to use and will not damage fuel injectors or any other part of the engine, fuel lines, or fuel tank. On the contrary, it helps improve engine performance by preventing the formation of gums and varnish that can clog fuel injectors and by cleaning the entire fuel system, including the injectors.
STA-BIL contains a fuel injector cleaner that helps to improve engine performance by keeping the fuel system clean and functioning properly. This is especially important in engines that tend to sit between uses, such as boats or lawnmowers, where corrosion is a concern due to the collection of water in the gas tank. STA-BIL's fuel injector cleaner removes water from the fuel tank and cleans the injectors, preventing corrosion and keeping the engine running smoothly.
The STA-BIL 360 Marine Fuel Stabilizer, for example, is designed to increase power by stripping away carbon build-up, gum, and varnish that can inhibit engine performance. It is recommended for use at every fill-up to provide year-round protection against corrosion. Similarly, the STA-BIL Diesel Fuel Stabilizer is designed to be used with all diesel engines and fuels, and it also cleans and lubricates fuel injectors to improve performance.
STA-BIL's fuel injector cleaner is an important component of its overall fuel stabilization and protection capabilities. By keeping the fuel system clean and corrosion-free, it helps to ensure that the engine runs efficiently and effectively, preventing performance issues and potential damage caused by clogged or dirty fuel injectors. This makes STA-BIL a valuable tool for maintaining and optimizing the performance of various types of engines and equipment.
It is important to note that while STA-BIL is safe to use, it is always recommended to follow the directions on the product label, including the recommended dosage rates, to ensure optimal performance and avoid any potential issues.

STA-BIL can be used for year-round fuel protection and storage
STA-BIL is a versatile product that can be used for year-round fuel protection and storage. It is safe to use in fuel-injected and carburetted engines and will not harm fuel injectors, fuel tanks, or engines. In fact, STA-BIL helps to improve engine performance by preventing the formation of gums and varnish that can clog fuel injectors. It also includes a fuel injector cleaner.
STA-BIL treats all types of fuel, including ethanol blends from E-10 to E-85, pure gasoline, and diesel. It is effective in all 2-cycle mixes and can be used in cars, boats, motorcycles, lawn equipment, generators, and outdoor equipment. The recommended dosage is 30ml of STA-BIL for every 9.5-19L of fuel, depending on the specific STA-BIL product.
STA-BIL is especially useful for seasonal equipment, classic cars, or boats that are used infrequently and stored for long periods. It helps to stabilize the fuel and prevent engine failures during storage. STA-BIL can keep fuel fresh for up to 12-24 months, depending on the product and storage conditions.
It is important to note that STA-BIL should be added to fresh fuel for optimal performance.

STA-BIL is safe for all diesel engines and fuels
STA-BIL is a fuel stabilizer that is safe to use with all diesel engines and fuels. It is designed to prevent sludge and sediment formation, and the darkening of diesel fuel. STA-BIL contains high levels of detergents and lubricity agents, which help remove sediments and fuel system deposits. It also lubricates critical fuel system components, including fuel injectors, to keep your diesel engine running smoothly.
STA-BIL is effective in all 2-cycle mixes and can be used with all types of fuel, including every ethanol blend (from E-10 to E-85), pure gasoline, and diesel. It is ideal for gas engines that operate with ethanol-blended fuel and can be used in cars, motorcycles, boats, and outdoor equipment such as lawnmowers and generators.
One of the key benefits of using STA-BIL with diesel fuel is its ability to remove water. Water attraction can occur within any fuel tank, but diesel fuel stored for long periods is more likely to draw in moisture from the air, leading to a gummy mess that clogs the system. STA-BIL demulsifies the water, breaking it into small droplets that drop to the bottom of the fuel tank. This allows the fuel/water separators to remove the water, ensuring the fuel can move safely through the system without causing corrosion.
STA-BIL is recommended for use at every fill-up for year-round protection. It is safe for consumers to use in both two and three-cycle gasoline engines and will not harm the engine, fuel lines, injectors, or the fuel tank, even if over-treated with more than the recommended dose.
