Scotlands Ash Garage takes a lead role in reducing harmful emissions and saving motorists money with TerraClean. Didcot’s leading vehicle MOT, service and repair business is successfully helping motorists save money and reduce harmful emissions in its role as an authorised TerraClean service centre.

TerraClean is the only product of its kind in the motor industry. Suitable for petrol and diesel vehicles and taking less than an hour, a TerraClean machine connects to a vehicle enabling the removal of stubborn carbon, tar and varnishes – which significantly harm a vehicle’s performance – from a number of internal engine components.

The TerraClean service brings about an immediate, noticeable drive away difference with the vehicle showing increased fuel efficiency and better performance. TerraClean also increases the MOT test pass rate by reducing harmful vehicle emissions.

TerraClean is currently advertised on national digital and satellite TV stations and is endorsed by double BTCC champion Colin Turkington. Closer to home, Scotlands Ash Garage is active on Facebook and also advertises within the local community, most notably Didcot railway station.
