We all know how important it is to go to the doctors for a checkup to make sure everything is running smoothly. Well the same goes for our cars! When a car is designed, manufacturers set out a service schedule for the car, which they believe will keep it running reliably and safely.

If you are unsure about what type of service your car requires then be sure to check your manufacturer guide book as this will have all of the relevant details in it. Failing that give us a call or an email and we'll be happy to help you out.

Remember the smile on your face when you drove your car for the first time? EDT can give you that smile back again after we have given your car our Engine cleaner treatment. With your engine performance and driveability improved, more responsive power delivery, and smoother, quieter running, your vehicle will feel as good as new.

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 drivability.

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 mineral oil.

We currently have experienced average emission reductions on cars tested of 69% on CO and 58% on diesel smoke, as of September 2017. Together with many testimonials on the enhanced performance and drivability after an Engine Decontamination Treatment (EDT) has been carried out.

At DMS Auto Services Our goal is to resolve all vehicle repair issues in a professional environment. We hope to win every customer’s trust and confidence by treating them fairly and with the highest ethical standard. We strive to provide the best car repair experience to our customers.
