Gilbert Auto Repair

Answer: 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 thro ... read more

A lot of gas is wasted in dirty fuel delivery systems.  Let’s start at the tank.  The gas tank gathers of dirt, rust and sediment over the years.  That’s why there’s a fuel filter to clean the fuel after it leaves the tank.  A dirty filter will rob the engine of the clean gas it needs to run efficiently. The fuel intake components get coated with gum and varnish over time.  This results in fuel being delivered inefficiently and some of that gunk getting into the engine.  A fuel system service will leave your intake as clean as a whistle.   The big fuel thief is dirty fuel injectors.  They deliver fuel to the engine at a specified pressure and in a specific spray pattern.  When they’re clogged, the fuel doesn’t get atomized the way it’s supposed to and doesn’t get burned as efficiently. See your owner’s manual or ask your service advisor for when fuel system cleaning is recommended
