FAQ

At what mileage should the carbon clean be performed?

Carbon Doctor recommends the first clean to be done prior to 50,000km. The onset of the negative affects start prior to this with consumption taking a dive as soon as 30,000km. Many car owners buy their vehicles used and have never realized how the car ran from day one. Various examples of build up over different mileage can be seen in our gallery.

Will I save on fuel?

All customers have shown a increase in engine efficiency with some models showing as much as a 3L/100km improvement after the carbon clean. The improvement is due to a change in the torque characteristic of the engine resulting in less throttle useage.

How will my performance change?

Most vehicles show a large increase of torque from idle. On naturally aspirated cars it's a serious restriction of the ports resulting in significant power losses.

On turbo cars the spool up is far quicker and the boost hold at high rpm lasts longer. Cars with detonation problems benefit greatly allowing the DME to adapt and use more timing.

All vehicles show a smoother and quieter idle and ride.

Will I need to retune my car?

The DME will correct for the more airflow over the initial first 30km. A retune is not necessary unless vehicles where having difficulty running higher stage modified ecu maps.

Will the Carbon Clean affect my warranty?

At Carbon Doctor we perform a maintenance clean that is non detectable by the agents. OEM gaskets and seals are used on all vehicles and utmost care is taken in re installing the stock components using recommended manufacturer torque settings.

How long does the process take?

We aim for a same day turnaround but prefer receiving the vehicle the evening before. This allows the cylinder head to cool down and the carbon build up hardens from a hot tar like paiste to a harder compound allowing for a more affective clean.

Is my car affected?

All direct injection vehicles are affected by carbon build up. Email us at info@carbondoctor.co.za if you are unsure if your car is fitted with direct injection.

How much does it cost?

Each vehicle varies in complexity. Please email us at info@carbondoctor.co.za to get a price on your model.
