Fuel treatments or fuel additives are fluids that are put directly into your car's fuel tank. They are designed to reduce engine wear and the build-up of deposits on many parts of your car, including the intake valves, carburettor and fuel injectors. They improve performance by reducing friction in the car's systems, sometimes by lubricating the different parts. Their use can solve many engine problems.
Injection cleaners are widely promoted fuel additives available from any store that sells auto maintenance products. They can be either a simple, pour-into-your-fuel-tank product or a complex, specifically-built cleaning and testing machine. The former is the most common.
Fuel injectors have to be cleaned because they often become clogged with the residue caused by the evaporation of the fuel in the injector nozzle when your car is stopped. This disrupts the fuel injector's spray pattern and reduces the flow of fuel to your engine, causing flats spots and hesitations. Certain fuel additives have injector cleaning capabilities when poured into your fuel tank. However, it is difficult to gauge how effective the treatment has been without taking apart the car to visually check.
Treating your engine with fuel additives can reduce your car's oil consumption and engine smoke. This can improve your car engine's compression and help your engine run quieter. Engine treatments can also extend the life of your car's engine by reducing the internal friction.
High-grade fuel additives treat the friction in your engine at its "source". Instead of simply lubricating the metal, these additives bond to the metal surfaces inside your engine to reduce friction when the car is started up. This is especially significant because most engine wear occurs when your car starts up. Engine treatments can also reduce the wear of your engine during high stress or high temperature operations such as off-road driving.
