Pour directly into the fuel tank
To use Lucas Fuel Injector Cleaner, purchase the correct product for your vehicle and pour it directly into your fuel tank. The process is simple and can be completed in just a few minutes.
First, locate the fuel tank cap and remove it. The fuel tank cap is typically located near the rear of the vehicle, although the exact location will vary depending on the car's make and model. Once you have found the cap, turn it counterclockwise to unscrew and remove it.
Next, take the Lucas Fuel Injector Cleaner and carefully pour the contents directly into the fuel tank. Pour slowly and carefully to avoid any spills or messes. The amount you should pour will depend on the size of your fuel tank and the severity of the issue you are trying to address. As a general rule, for every 10 gallons (38 litres) of fuel capacity, use one bottle of Lucas Fuel Injector Cleaner.
After pouring the cleaner into the fuel tank, replace the fuel tank cap by screwing it back on tightly. Ensure it is secure to prevent any fuel evaporation or spillage while driving. Once the cap is securely tightened, you can start the engine and begin driving as usual.
It is recommended to use Lucas Fuel Injector Cleaner with every fill-up, or at least once every 3,000 miles (4,800 km) to maintain optimal engine performance and fuel efficiency. This product helps clean and lubricate the fuel injectors, improving engine performance and fuel mileage while reducing harmful emissions.
