Steve arrived to give my Jaguar xfs an engine carbon clean. Presently on 107,000 miles. Explained the process and was obviously very knowledgeable about the process and expected outcomes. And he was a thoroughly nice chap.
The V6 in the xfs is a quiet, smooth, powerful unit and I was not sure of what improvements I would get. Well, I’m impressed. The power delivery is smoother, the engine even quieter and 6 mpg better to boot.
If you want to do one thing to maintain and improve your motor, then this is what you should do.
Had the pleasure to meet Adrian this morning who performed a carbon clean on my bmw 525d
Very knowledgeable guy, I was really impressed.
Car drives much better now, highly recommend.

Thanks Adrian

Iv had the pleasure of having 2 Carbon cleans from both Adrian and Mark. Both lovely gentlemen and you can tell they love what they do. My car failed on emissions and this helped me get the car through the test, and at the time, I REALLY needed a pass because I couldn’t get anywhere. These guys saved me. Not only that, it’s a lot cheaper here compared to other places also. Thank you so much and look forward to seeing you in future endeavours.

What is an Engine Carbon Clean?


A professional engine carbon clean helps restore lost performance by removing carbon build-up from key hot-running engine components.

Using a safe and effective process and endorsed by Which? Trusted Traders, we target areas such as the turbo, combustion chamber, injector tips, pistons, cylinders and catalytic converters.

This helps the engine run smoother, quieter and with less strain, supporting the long-term health of the vehicle.

Our service focuses heavily on live data engine diagnostics throughout the clean to help us identify underlying issues affecting performance and help you prevent future repair bills.

If you’re searching for a carbon clean in your area for your own car, van or a fleet, our mobile service delivers a safe, controlled engine carbon clean wherever you are.

What Causes Carbon Build-Up in an Engine

All petrol, diesel, LPG and hybrid engines create carbon as they burn fuel. When the engine is new the levels are low so everything runs smoothly, quietly and efficiently.

As the miles add up incomplete combustion becomes more common and carbon deposits start to stick to internal parts. This can happen from around 10,000 miles.

carbon build-up

Why modern engines suffer more with carbon

Newer engines are built for performance and low emissions which means they rely on more complex systems. Features such as direct injection, swirl flaps and tighter tolerances make them far more sensitive to dirt. Even with cleaner fuels carbon still builds up over time, especially on cars that do short trips or stop–start driving.

An engine carbon clean is especially valuable for:

Carbon Clean for engine

How carbon build-up affects your engine

As carbon gathers inside the engine it becomes harder for it to run smoothly and it starts to get noisier, using more fuel and generally performance starts to decline.

Just to maintain an idle it starts using more fuel which impacts fuel economy, increases emissions and creates even more carbon. Over time you may notice:

carbon build-up

Why A Regular Engine carbon clean helps

A professional engine carbon clean removes these deposits and helps the engine breathe and burn fuel properly again. Most drivers notice smoother running, improved throttle response, better fuel economy and lower emissions.

Regular cleaning is a simple way to keep the engine healthy and avoid unnecessary wear and tear.

What makes us different? Our focus on Live data Diagnostics throughout the clean. It’s essentially a health check and detox for your vehicle.

Ideal Preventative Maintenance

A regular engine carbon clean helps remove carbon build-up before it begins affecting drivability. Most people are coming back to us approximately every 20k miles, but anything over 10k miles is acceptable.

Restore Power, Performance, Fuel Economy and Emissions

Cleaning the engine regularly helps limit the amount of carbon entering the inlet manifold, EGR and DPF going forward, which can help reduce the frequency of regenerations.

Ideal Restorative Maintenance

Removing carbon deposits from the hot side of the turbo and internal engine components helps restore performance and reduce the risk of mechanical issues such as a sticking turbo and limp mode problems.

Carbon Cleaning FAQs

What does an Engine Carbon Clean do?

Keeping your engine cleaned on a regular basis helps prevent issues such as DPF issues, MOT emissions failures or sticking turbos. An Engine Carbon Clean is great at cleaning up the back of a turbo, combustion chamber, injector tips, pistons, cylinders and cats to get a vehicle running smooth, quiet, responsive, economical and emissions friendly again.

Can you carbon clean a petrol engine?

Yes. All hydrocarbon engines create carbon build up depending on the mileage, driving style, journey length and fuel quality used. You can clean petrol, diesel, LPG, hybrid or anything else such as methane.  Not just cars and vans, but we also work on boats, tractors, tanks, generators, landfill engines, anything really.

What are signs of carbon build up?

Typical symptoms include a decline in fuel economy, noisier engine, increased vibration, sluggish response and smoke/emissions levels. As fuel economy and emission targets have got stricter over the years the engine components have been developed and added in order to keep the soot within the vehicle rather than passing it out through the exhaust. This then clogs up EGR valves, inlet manifolds and DPFs.

When should you Engine Carbon Clean?

If you have just bought a vehicle or warranty is due to expire then it is a perfect time to get it checked out and cleaned up. As part of your regular maintenance plan an ideal time is just prior to a service or MOT to help keep your vehicle running smoothly, quietly, economically and with low emissions. Most people are coming back for repeats approximately every 15-20k miles based on driving style, journey length and fuel quality.

Does Carbon Engine Cleaning actually work?

Yes it does and it is very good at what it does as long as the relevant pre-checks are performed to ensure an effective clean and critically it is done by someone who is properly trained, certified, with the right approach and equipment.
