Effective and economical engine cleaning that makes a real difference.


An effective way to clean carbon deposits from your engine.

The combustion process that powers your vehicle will always produce carbon as a waste product. This carbon collects within your engine and can form deposits that can clog it, preventing it from functioning as it should. FlexFuel Hy-Carbon is a unique system that can remove these deposits safely.

Soot deposits are commonly found in cylinders, pistons, particle filters, EGR valves and turbos, and can cause expensive problems. FlexFuel Hy-Carbon combines hydrogen and oxygen during the combustion process, destroying the carbon deposits and expelling them through the exhaust system. It’s a non-corrosive process that leaves your engine running smoothly and that can reduce pollution in your vehicle’s exhaust by up to 50%. 

Regain power, reduce fuel consumption, and prolong the life of your engine components by making sure that carbon deposits are effectively removed before they can cause problems. Try FlexFuel Hy-Carbon for yourself – get your vehicle booked in today.

Thorough cleaning for your engine

The FlexFuel Hy-Carbon process can remove soot deposits from:


  •  The ERG valve

  • Engine valves

  • Your vehicle’s turbo

  • The particle filter

I drive an old Mercedes C220 diesel which I took in for a service and was introduced to HY-CARBON series engine cleaning by the team at Studley Green. I was hesitant at first, but I decided to go ahead as I’ve always been able to trust information and service that I have received from Studley Green staff, and I must say once again, I’m very pleased that I did it - the HY-CARBON engine cleaning makes my car performance much better. I do not know anything about mechanics or engine cleaning, but I do know my car feels like it’s had all it bolts and every screw tightened and it’s running like a dream..."
