How to Use Car Diesel Additives
1. Determine the Correct Dosage
The first step in using diesel additives is determining the correct dosage. This is crucial for achieving the desired benefits without causing any harm to the engine or fuel system.Alwaysrefer to the additive manufacturer's instructions for specific dosage recommendations. Dosage is usually expressed as a ratio of additive to fuel, such as "1 ounce per 10 gallons of fuel." Using too little additive may not provide the intended benefits, while using too much can potentially damage fuel system components or alter fuel properties.
To optimize the dosage, consider the size of your fuel tank and the concentration of the additive. Accurately measure the additive using a measuring cup or dispenser to ensure precise dosing. For example, if your vehicle has a 20-gallon fuel tank and the recommended dosage is 1 ounce per 10 gallons, you would need to add 2 ounces of the additive to a full tank.
2. Add the Additive to the Fuel Tank
The next step is to add the additive to the fuel tank. This is typically done when refueling the vehicle.Beforeadding the additive, make sure the fuel nozzle is removed from the tank and the fuel cap is securely closed.
Pour the measured amount of additive directly into the fuel tank. It is generally recommended to add the additivebeforefilling the tank with diesel fuel. This allows the fuel to mix thoroughly with the additive as the tank is filled, ensuring even distribution. However, some additives can be added after filling the tank, especially if they contain mixing agents.
A common mistake to avoid is spilling the additive on the vehicle's paint or body. Diesel additives can be corrosive and may damage paint if left unattended. If spillage occurs, immediately wipe it off with a clean cloth and wash the area with soap and water.
