Fuel System Cleaning

We are asked quite a few questions when we recommend a fuel system cleaning.  The most frequently asked questions are:  ” I haven’t noticed any problems so why do I need this service?”  The answer to this question is that most vehicles are equipped with a “knock sensor” which decreases the engine’s performance to prevent harmful knocking conditions.  You might not notice the reduced performance and fuel economy because it happens gradually.  After the fuel system cleaning you may notice a dramatic increase in the performance and fuel economy of your car.

We are also asked, “why does my car need a fuel system cleaning?”  Our cars have fuel systems that have fuel injectors, intake ports, intake valves, combustion chambers, throttle body and an intake manifold.  Each of these areas can have deposits build up that can create problems in the engine.  If you have experienced rough idling, engine stalling or hesitation, loss of power or engine knocking, the problem might be in your fuel system.

Another question we get is,” what’s the difference between a fuel system cleaning and a tune-up?”  When you have the fuel system cleaned there aren’t any parts replaced.  When you have a tune-up the spark plugs are usually replaced.  The fuel system service cleans the existing parts in the engine so they run like they were new.  Since we haven’t replaced any parts we’re often asked what we actually do to the car.  What our technician will do is attach cleaning tools to the fuel system that clean deposits from the fuel injectors, intake valves and the combustion chamber.  The deposits are also removed from the air intake system.   These deposits occur as a by-product of burning gasoline and need to be removed on a regular basis.  We recommend that you have a fuel system cleaning every 36,000 miles to keep your car running at it’s best.
