●Reduced fuel economy

●Poor acceleration

●Rough starts

●Shudders when idling

Although some of the above could be related to other car problems, the above could be a sign that all you need is your fuel system cleaned.

What does a fuel system service entail?

When you take your vehicle in to get the fuel system cleaned, mechanics will take a look at the system carefully to ensure everything is cleaned and maintained correctly. It will also ensure they clean the necessary parts without causing damage to those more delicate components. Here is what the process entails:

Injector Clean

Fuel injectors take the petrol or diesel and spray it as a mist and the mechanics will start by clearing the injectors of any debris which can clog them and stop them from working correctly. You can expect to replace your fuel injectors every 30,000 miles.

Fuel Varnish Removal

Varnish can easily build up in your car’s fuel system and this can cause the throttle to stick, making it impossible to control air intake. When your mechanic cleans the throttle, they will ensure the sensors are also operating as expected. Varnish also impacts the valve operation and this will be cleaned carefully also.

Fuel Filter Change

The fuel filter has been designed to keep the impurities and debris out of the delicate parts of your engine but overtime, this will get build-up and it needs to be replaced.

Add Fuel Additive

Finally, the mechanic will add a fuel additive directly to your tank of fuel to get rid of any moisture build-up and will also maintain the injector and other parts to make sure you get the most of your fuel system cleaning.
