Our machine carries out a unique engineering process which removes all the sludge, varnish and debris that builds up in the engine. Improving the engine’s coefficient of friction allows the new oil to perform to its maximum capabilities. This then has a positive impact on fuel economy, CO emissions, engine performance and driveability.

Our system heats and pulses a soya based oil in and around your engine’s oil ways, breaking down and removing up to half a litre of harmful residue that is normally left in the engine after a conventional oil change.

Once broken down, our system then vacuums the deposits out of the engine through a 5 micron filtration system see Image below.



Our engine cleaner device is fully automated and once connected takes less than fifteen minutes to complete a full clean of your vehicle’s engine. It operates using a bespoke, environmentally-friendly, bio-fuel, white food grade oil.

We currently have experienced average emission reductions on cars tested of 69% on CO and 58% on hydrocarbons, as of September 2015. Together with many testimonials on the enhanced performance and drivability after an Engine Decontamination Treatment (EDT) has been carried out.

See how clean the oil is before and after the treatment on your dipstick.
