Question: What benefit will I get out of a fuel system cleaning?


Well, the dirtier your fuel system is, the bigger the improvement you’ll see in performance and fuel economy.  But don’t wait until your engine is running poorly, you’ve wasted hundreds of dollars in gas or maybe even damaged your fuel injectors and catalytic converter.


Look, gasoline is a petroleum-based product and will leave some residue, gum and varnish along the way.  Some of that can find its way into your fuel injectors and interfere with their job.  The fuel injectors do just that – inject fuel into your engine.  They spray a precise amount of fuel, at a precise time, in a precise pattern, at a precise pressure.  When they are dirty this precision just isn’t possible.  So, your engine can run rough.  Also, carbon deposits build up on valves and in the combustion chamber.  Fuel economy suffers and performance is degraded. 

These poor conditions allow excess unburned fuel to pass out through the exhaust to accumulate in the catalytic converter – which can lead to it overheating and failing. 

So bad fuel economy, poor engine performance and the chance of having to replace expensive fuel injectors and catalytic converters – all potential problems associated with a dirty fuel system. 

A professional fuel system cleaning cleans out deposits, fuel injectors and the air induction system.  You get optimal power, performance and fuel economy and it helps avoid costly future repairs. 

Now I said professional fuel system cleaning: this isn’t just pouring a bottle in the gas tank.  Cleaner is added into the fuel system with a special tool attached to a vacuum source and there is some manual scrubbing of the throttle body and air induction system.

If you are experiencing a rough idle or unusually poor fuel economy, ask you service advisor if a profession fuel system cleaning is in order.
