Usage
This cleaner is intended for use by everyday drivers, fleet operators, and automotive enthusiasts who want to preserve engine health and reduce environmental impact. To use, simply pour the recommended amount of cleaner into the fuel tank before refueling, then fill the tank with gasoline or diesel as usual. The cleaner mixes with the fuel and circulates through the fuel system, reaching the injectors, combustion chambers, and exhaust components. It works continuously during engine operation, breaking down carbon deposits as the engine runs. Ideal for vehicles with over 75,000 miles, the product helps restore performance that may have degraded over time due to accumulated soot. It is also suitable for newer vehicles that benefit from preventive maintenance, ensuring that the catalytic converter remains clean and efficient from the start. The portable size allows you to keep a bottle in your glove compartment or toolbox, making it easy to apply during any fuel stop, whether at a service station, a home fuel pump, or a remote location. Regular use—once per fuel fill—provides ongoing protection and can extend the life of expensive emissions components.
