Use a fuel tank treatment to clean varnish and contaminants from the fuel system
Diesel fuel tank treatments are an effective way to clean varnish and contaminants from the fuel system. These treatments typically use detergents and solvents to break down and remove carbon deposits, varnish, and other contaminants from the injectors, lines, and combustion chamber.
One such product is Clear-Diesel Fuel & Tank Cleaner, an advanced diesel fuel and tank cleaning technology. To use this product, first, drain any excess water and fuel contaminants from the bottom of the fuel tank until diesel fuel appears. Next, add the entire contents (typically 16 ounces) of Clear-Diesel to each 40 gallons of fuel tank capacity. Finally, fill the tank with diesel fuel. It is recommended to use this treatment at least quarterly or as needed for immediate clean-up.
Another option is to use a product like Sea Foam, which can be added directly to the fuel tank. It is recommended to add a can of Sea Foam to the remaining fuel, followed by a gallon of fresh fuel. The engine should then be started and run for about 8 minutes to allow the Sea Foam to draw through the carburetor circuits. After shutting off the engine, let the vehicle sit overnight or longer (up to 3 days). The next day, add another gallon of fresh fuel and run the engine for 5 to 8 minutes. Finally, take the vehicle for a short drive to create upper engine heat and compression, allowing the Sea Foam to continue cleaning as you drive.
Using a fuel tank treatment is an effective way to maintain a clean fuel system and prevent issues caused by contaminated diesel fuel, such as clogged injectors and filters. These treatments can also improve engine performance and promote cleaner combustion, helping vehicles meet emissions standards.

Improve engine performance with octane or cetane boost treatments
To improve engine performance, octane or cetane boost treatments can be used. These treatments are designed to increase the ratings of octane (gasoline) or cetane (diesel) for improved engine performance.
Octane and cetane are often referred to as equivalent properties for gasoline and diesel fuel, respectively. A higher cetane rating in diesel fuel indicates that it will ignite more quickly and efficiently in the engine's combustion chamber. This results in better engine performance, including better starting performance, smoother engine operation, reduced engine noise, and fewer emissions.
Similarly, a higher octane rating in gasoline prevents pre-ignition, where the gas ignites too quickly. Using gasoline with a poor octane rating can lead to pre-ignition, causing the engine to run too quickly and burn fuel inefficiently.
There are several ways to boost the cetane rating of diesel fuel. One method is to add a chemical with a higher cetane rating to the fuel, thereby increasing the overall cetane rating of the fuel blend. The industry standard for cetane improvers is 2-ethyl hexyl nitrate, which is effective at raising the cetane rating without causing engine problems. However, it is important to exercise caution when using cetane boosters, as some products may contain harmful additives or not have the necessary active ingredients to be effective.
Additionally, if the diesel fuel already contains a biodiesel blend, it may not require a cetane improver as the fuel may already have an adequate cetane rating. Furthermore, using a cetane booster with a rating higher than necessary (above 55) can deteriorate the fuel and reduce overall engine performance. Therefore, it is recommended to refer to the manufacturer's guidelines and use cetane boosters only when necessary to avoid potential issues.
In summary, octane and cetane boost treatments can improve engine performance by enhancing the combustibility of the fuel. However, it is important to select legitimate and safe products, follow manufacturer guidelines, and avoid using boosters unnecessarily to prevent potential engine issues.

Remove water and slime with a fuel polishing formula
Water has always been a problem in diesel fuel. Today's cleaner-burning fuels have lower sulfur content, making them more prone to water separation, contamination, and instability. This is where fuel polishing formulas come in.
Clear-Diesel Fuel & Tank Cleaner is an advanced diesel fuel and tank-cleaning technology that uses a Fuel Polishing Formula to remove water and slime, disperse fuel contaminants, and stabilize fuel during long-term storage. It can be used as part of a preventive maintenance program or for immediate clean-up of equipment or fuel storage tanks.
To use Clear-Diesel Fuel & Tank Cleaner, add the entire contents (16 ounces) of the product to every 40 gallons of fuel tank capacity. Then, fill the tank with diesel fuel. It is recommended to use this product at least quarterly or as needed.
It's important to note that this product should be added to the fuel and not to the diesel exhaust fluid tank. If possible, pump or drain excess water and fuel contaminants from the bottom of the fuel tank until diesel fuel appears.
While filtration can help remove water from diesel, it is not sufficient on its own. Fuel polishing is a technical cleaning process that combines filtration with other steps to effectively remove sediment, water, and microbial contamination from diesel fuel. This process can be applied to tanks of various sizes, from 20 to 10,000 gallons.

Next, drain the diesel fuel tank. This is a crucial step, as you want to remove as much diesel, water, and contaminants as possible. Use a hand pump to suck out any remaining fuel, paying particular attention to the bottom of the tank, where these residues tend to accumulate. Continue draining until you see diesel fuel appearing, indicating that most of the excess water and contaminants have been removed.
Now, it's time to start cleaning with the hose and hot water. Attach a hose to a source of hot water, ensuring the water temperature is high but safe for handling. Begin rinsing the interior of the tank with the hot water, using a degreasing agent to help break down any remaining grease and grime. Throw or spray the hot water around the tank's interior, ensuring all surfaces are thoroughly wetted. Use a long-handled brush to scrub all corners and surfaces, dislodging any stubborn deposits. Continue rinsing and scrubbing as needed until the interior looks clean.
After the tank is clean, it's essential to dry it thoroughly. Use a hot air gun to blow hot air into the tank, accelerating the drying process. Leave the tank for a couple of days to ensure it's entirely dry. Finally, seal the tank by fitting the access hatches, if applicable, and bolting it securely. Reconnect the tank to the fuel filter and engine, and your diesel fuel tank is now clean and ready for use.
This process of cleaning a diesel fuel tank with a hose and hot water is a detailed and hands-on approach. It ensures the tank is thoroughly cleaned and dried, helping to prevent future issues with fuel contamination and sediment buildup.
