Engine Decontamination Treatment

Embracing the very latest motoring technology, EDT is a revolutionary Engine Decontamination Treatment that has been expertly formulated to remove all of the harmful, unwanted deposits that can build up in your engine over time.

Designed to optimise the performance of your vehicle, and of course, expand its lifespan by keeping your engine in the very best condition, EDT treatment has been developed over the past 20 years, with over 1 millions treatments used in all corners of the globe.


How does EDT work?

EDT is a performance focused and environmentally friendly cleaning solution that can be used to successful remove harmful deposits from your engine, without the need for major engine dismantling.

This treatment involves using bio-grade oil, which is heated, pressurised and then distributed around the engine in order to thoroughly clean your engine.


What are the benefits of EDT?

There are many benefits that come hand in hand with this treatment including improved fuel economy, reduced emissions, reduced internal engine friction, improved oil circulation, improved driveability, and enhanced performance and engine life!

You should really think of EDT as removing the cholesterol from the heart of your car.

Hardings did a terrific job on my exhaust. The customer service at the garage was brilliant.

I brought my BMW here a number of times now, so my feedback is based on a cumulative experience, not just one-off. There are standard car services out there - you know, the ones which will try to do a minimum work to "cover" issue symptoms, get paid and move on to a next customer. And there is Mike Harding's one. Who always strives to resolve the problem entirely, not just to cover it up. Who provides a detailed report with empirically proven underlying cause and steps taken to rectify it. Do you want to pay less... but a few times? Choose other service. Do you want to pay a fair price once and really forget about your problem for good? I suggest you speak with Mike.

I cannot fault the fantastic team at Harding Auto Services! I needed some major repair work done on my Landrover Defender and they were helpful and kept up communication the entire time (my vehicle was with them for approximately two weeks). When it came to specifing what work needed to be done and the overall cost they were completely transparent so there were no "nasty surprises" when the job was finished. They obviously know what they are doing with classic Landrovers and I will 100% recommend them to anyone!
