We seek out world-class products and services that will enhance the sustainability of the planet while also delivering considerable financial benefits for our clients.
X-Carbon is one of RunGreen’s first products to be launched, that when added to fuel restores and maintains engine performance to the highest near-new levels. It does this by removing the air entrained in the fuel so it combusts more completely, cleaning the engine, improving fuel efficiency and engine life, cutting noxious emissions and so improving air quality.

X-Carbon’s use will also help clients achieve their Environmental, Social and Governance goals and can reduce their carbon-offset requirements.

RunGreen International has the exclusive agency for X-Carbon in the UK, Europe and Africa, manufactured only in the USA by a company that owns the Intellectual Property Rights worldwide.

RunGreen’s Fuel and Emissions Monitoring Services, provides research and input that can deliver greater efficiencies to clients with fleets of commercial vehicles.

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.

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.
