Trialing and testing amongst our customers' vehicles of varying ages, models and situations to date have shown an average improvement of 26% MPG and emissions cut to almost zero. One high profile test case was BBC TV's former Top Gear presenter Jeremy Clarkson's Lamborghini Gallardo. It was tested on VOSA approved rolling road and when using X-Carbon showed significant improvements in performance: horse power rose by 16.2, torque improved by 17.6 pounds per square foot and hydro carbon emissions were cut by a significant 30%.

In an every day environment the exact impact of X-Carbon on a vehicle is harder to estimate. All new engine’s emissions are tested and most are reported on at point of purchase. When an engine is new and clean of any deposits caused by use, it should perform at its peak levels, matching the manufacturer’s claims.

With use, in the engine’s chambers where fuel is burned, there will be varying amounts of deposits, generally of carbon. The negative effects of this are well known as causing cavitation, misfire, reduced engine performance, sluggish acceleration, reduced fuel economy and increased emissions.

The use of X-Carbon in the fuel will restore the engine to the same state of cleanliness that existed when the engine brand new. We cannot predict accurately what levels of emissions reduction or fuel economy X‑Carbon will facilitate without measuring a vehicle’s levels, nor can we assess how ‘dirty’ the engine is. We do know that in most non-new cars a significant improvement will be achieved up to near new levels and, for new cars and those that use X-Carbon regularly, they will at least maintain their performance, reduce maintenance and increase engine longevity.

Through using X-Carbon, many of our clients have reported improvements of 20-33% or more in fuel efficiency. For emissions, the changes are most notable for many during MOT testing, enabling even older, high mileage cars to pass the emissions test.
