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

FREQUENTLY ASKED QUESTIONS ABOUT MOTS
How is EDT different from a standard engine flush?
A basic engine flush is usually added to old oil shortly before a routine oil change and works for a short period while the engine idles. EDT is a much more controlled and thorough process. It uses heated, pressurised bio-grade oil circulated throughout the engine to properly clean internal components. It’s a far more advanced and structured treatment compared to a quick additive based flush.
Will I notice a difference straight away?
Most customers do and after treatment, engines often feel smoother and quieter, particularly at idle. Throttle response can improve, and the engine may feel freer when accelerating. While it’s not a “performance upgrade” in the tuning sense, it restores lost efficiency by removing restrictions that have built up over time.
Is EDT suitable for both petrol and diesel vehicles?
Yes, it is. Whether you drive petrol or diesel, deposits can still form internally, and EDT works effectively on both engine types. If you’re unsure whether your vehicle is a good candidate, we’re always happy to assess it and give you honest advice before proceeding.
Is Engine Decontamination safe for older or higher-mileage vehicles?
In many cases, older engines benefit the most from this. Of course provided the engine is mechanically sound, EDT can help restore smoother operation and improve oil circulation. Before carrying out any treatment, we’ll check the condition of the vehicle to make sure it’s appropriate. If we feel it isn’t suitable, we’ll explain why.
How long does the typical EDT treatment take?
The process typically takes a few hours from start to finish. It’s not an all-day job, but it’s not rushed either. We allow the system enough time to circulate the heated cleaning oil properly so the treatment can do its job effectively.
Will EDT reduce oil consumption?
If oil consumption is being caused by internal build-up restricting proper oil control, EDT may help improve the situation. However, if excessive oil use is due to mechanical wear or damaged components, cleaning alone won’t fix that. We’ll always manage expectations and explain what the treatment can realistically achieve.
Can EDT help with noisy or rough-running engines?
If roughness or increased engine noise is linked to internal contamination or restricted oil flow, EDT can often help smooth things out. By reducing friction and improving lubrication pathways, the engine may run quieter and more consistently. That said, it’s not a substitute for mechanical repairs where parts are worn or damaged.
How often should Engine Decontamination be carried out?
There’s no fixed rule, as it depends on how the vehicle is used. Cars that mainly do short journeys, urban driving or long service intervals tend to build deposits more quickly. We’re always happy to look at your mileage, usage and service history and recommend what makes sense for your vehicle.
Does EDT replace regular servicing?
No and instead it complements it. Regular oil and filter changes are still essential, and EDT works alongside routine servicing by giving the engine a deeper internal clean that normal maintenance doesn’t achieve. Think of it as preventative care rather than a replacement for standard servicing.
