Subaru WRX Fuel system clean
Does my Subaru WRX need a fuel system clean?
A fuel system clean is carried out as a maintenance task or when a Subaru WRX is running rough, usually due to the build-up of contaminants in the fuel system. The fuel system cleaners chemicals have a way of vanishing the nasties that can cause fuel system problems, but it’s not a magical cure for all Subaru WRX fuel system problems.
Subaru WRX’s can get a build-up of dirt, grime and carbon deposits inside the fuel system. A fuel system clean is similar to a fuel injector clean except it’s a more powerful clean for the system. A fuel system clean can remove water and fuel deposits, clean and lubricate injectors, valves, rings, cylinder heads and combustion chambers. The Subaru WRX’s throttle body and throttle plate/butterfly valve will typically be cleaned of dirt and grime at the same time.
If the fuel system clean is performed as a regular maintenance task then the cost won’t be too high, but if the Subaru WRX has a history of performance issues, then more time may be needed to assess the fuel system. The cost can range from 10’s of dollars and move up into the hundreds to clean the fuel system.
A qualified mechanic can carry out a fuel system clean. They can do this in a workshop or a mobile mechanic can come out to your Subaru WRX and carry out a fuel system clean.
