Application Steps: How to add cleaner to diesel fuel tank
Adding Premium 245 Diesel Fuel System Cleaner to your diesel fuel tank is a straightforward process that can significantly enhance engine performance and longevity. The first step is to determine the correct dosage based on your fuel tank capacity. For most passenger vehicles, a single bottle of Premium 245 is designed to treat up to 60 gallons of diesel fuel. If your tank holds more, adjust the dosage proportionally—for instance, two bottles for a 120-gallon tank. Always refer to the product label for precise measurements to avoid under or over-treatment.
Once you’ve calculated the correct amount, ensure your vehicle is on a level surface and the engine is turned off. This minimizes the risk of spills and ensures accurate fuel level readings. Locate the fuel filler cap and remove it carefully. If your vehicle has a fuel tank lock, unlock it first. Pour the cleaner slowly and steadily into the tank, avoiding spills that could damage the exterior of your vehicle. A funnel can be a useful tool here, especially for tanks with narrow openings, to prevent wastage and ensure all the cleaner enters the tank.
After adding the cleaner, securely replace the fuel filler cap to prevent contamination or evaporation. Start the engine and let it idle for a few minutes to allow the cleaner to mix thoroughly with the diesel fuel. This ensures even distribution throughout the fuel system, from the tank to the injectors. For optimal results, drive the vehicle immediately after treatment, as this helps the cleaner dissolve deposits and improve fuel flow during operation.
While the process is simple, caution is key. Avoid overfilling the fuel tank before adding the cleaner, as this can lead to spillage or reduced effectiveness. Additionally, store the cleaner in a cool, dry place away from children and pets, as it is a chemical product. Regular use, typically every 3,000 miles or as recommended by the manufacturer, can help maintain peak engine performance and prevent costly repairs down the line. By following these steps, you’ll ensure your diesel fuel system remains clean and efficient, maximizing both power and fuel economy.
