What is an X-Carbon Complete Subscription?
The most economic way to obtain the full benefits of X-Carbon is with a monthly subscription. It provides all you need over a year to clean your engine and keep it running to its optimum performance. Over a year we will send you 2 months of X-Carbon Boost and 10 months X-Carbon Regular.
How Much Do I Use?
Just 10 ml of X-Carbon is required for every 50 litres of diesel or petrol, added straight into the fuel tank, every time you add more fuel. Cars’ fuel tanks can hold an average up to 45-70 litres depending on their make and model. Like some advice? Please contact us.
X-Carbon
A revolutionary innovation.  Built from the same petrochemicals that are already in the petrol and diesel, X-Carbon releases the air from fuel, enabling more complete combustion, yielding substantial additional benefits.
Improved Fuel Economy
Customers save an average of 26% on fuel consumption.
Extended Engine Life
Fuel has greater lubricity and viscosity reducing engine wear, so your vehicle’s engine lasts longer.
More Responsive Acceleration
More instantaneous and smoother throttle response.
Reduced Emissions
Protect the planet’s future by cutting your carbon footprint.
Smoother Running Engine
More complete and consistent combustion results in a quieter, smoother driving experience.
Cut Maintenance Costs
Replace parts less often, as the engine is subjected to less wear and tear.

I have never seen a reaction take place this quickly as with X-Carbon. I could hear the engine get quieter. I could feel it get smoother. I noticed that the throttle response had improved.
Christopher Sawyer - Founder of TheVirtualDriver.com
For a truck to get 23 MPG is absolutely SHOCKINGLY GOOD with X-Carbon when the normal mileage is around 14 MPG. Thanks again for insisting I try it.
