Many of RunGreen's clients have now been using X-Carbon for several months at least. The surprise findings are that ... with fuel savings of 18% - 38% through using X-Carbon, they need to use 18% - 38% less X-Carbon, saving money in every direction.

X-Carbon packs a powerful punch with only 10ml of X-Carbon required for a 50 litre tank of fuel. Some clients who carefully monitor their fuel consumption have seen immediate fuel savings, smoother running and less black soot in their emissions. Other have seen the results after using X-Carbon regularly over 3 months - giving it time to clean out their carbon clogged engines and fully demonstrate it's effectiveness. A "good run" (i.e. over 40mph over a couple of hundred miles) generally gives clear signficant savings.

Our subscription offers the most economic way of purchasing X-Carbon - but find you need less due to its effectiveness in cutting your MPG?! Your subscription can be stopped and restarted at any time.

Not only fuel savings, but X-Carbon has helped many clients' vehicles pass their MOT tests where they had failed the emissions regulations previously. Fuel, oil and other filters are clogging less frequently, and maintenance costs have been less onerous. So X-Carbon not only saves you money, but helps you do your bit in cutting emissions and so helping us all.
