Like any other part of a vehicle, the fuel system is also likely to get clogged and dirty. As gas or diesel fuel travels from the tank through the filter, fuel pump and injector to reach the spark plug, dirt, debris and other deposits are bound to build everywhere.
When the fuel system is clogged with sludge, carbon, varnish or dirt, the gas does not get sprayed properly and therefore, fails to combust as needed, That is why fuel treatment for the system is neccesary. Lower power and mileage are bound to follow. As the buildup grows, it can also damage other engine parts leading to sluggish throttling, hesitation in acceleration, deteriorated performance and ultimately, complete shutdown of the engine.
There is no way out other than replacing all the fuel injectors or even completely overhauling the system. An extremely costly burden indeed!
Another way out
It follows that cleaning the fuel system is essential for restoring the economy and performance of the vehicle. In fact, this is a basic maintenance that can genuinely extend the life of the vehicle.
Premium fuel system cleaners are available in the market, that thoroughly clean the gas pump, fuel lines and injectors. All you have to do is pour the entire contents of the can into a nearly empty tank. Then continue to refuel up on gas as always. The pour-in additive will slowly clean the fuel system over a period of time.
Within a few days, fuel economy will improve, horsepower is restored, torque increases and harmful emissions are greatly reduced. The thorough cleaning will prevent any more knocking, pinging, hesitation and stalling in the engine. Very soon, the vehicle will be back to running like new.
