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!
