X-Carbon aims to restore an engine's performance to near new standards, but testing is proving it can do far better than that.

"AmSpec is a world-respected testing and certification company for fuel, so we are pleased to add their positive test results of X-Carbon to our armoury of proof that X-Carbon is safe to use and does what it says on the bottle. These tests show that the addition of X-Carbon does not affect the required specification for Diesel, Gasoline (Petrol) and, for the first time of testing in the UK, Kerosene and Marine Gasoil."

This year RunGreen’s clients have successfully trialled X-Carbon in their trucks and proven that it delivers significant fuel cost savings.

We show how X-Carbon can clean out carbon deposits from your engine, improving your fuel efficiency and engine performance, reducing the need for maintenance, as well as cutting emissions.

When presenting BBC TopGear Jeremy Clarkson test drove a Lamborghini Gallado and so liked it that he bought one and then let us test it, firstly without and then with X-Carbon added to its fuel.

X-Carbon's significantly positive impact on the running of generators is so quick and easy to see in these trials and has proved far more straight forward to measure than on vehicles, which are affected by a driver's style, journey type, speed, load and topography.

Managing and running a fleet of trucks is a demanding business, with so many different variables affecting cost and performance, impacting often narrow margins. RunGreen is helping companies to reassess their systems while trialing X-Carbon, which is proving to produce so many more benefits than originally anticipated.

X-Carbon trial shows promising results on a fleet of Volvo trucks.

Governments are putting huge pressure on businesses to cut emissions while offering few solutions. Yet they should seek to inform the public and companies of products like X-Carbon that can cut emissions safely at little cost.

Fuel price rises has led a drive for doing more with less - which is why adding X-Carbon to fuel to achieve this is catching people's attention.

Decarbonising fossil fuel in transport: have we been asking the wrong question? While we wait for the wider roll-out of future fuels such as hydrogen, biodiesel and electricity we regularly address the challenge to decarbonise transport now. In previous articles we have considered the role of additives in improving fossil fuel efficiency and reducing the emissions associated with its use, but now we hear from Rungreen, an environmentally friendly organisation looking to transform vehicle emissions by asking a very different question.
