Leon and Steve was very informative and answered any questions or concerns that I had especially DPF related. It has given me the necessary information on how best to pro-long the life of the DPF and hopefully prevent any likely costly repairs in the future. I would highly recommend!

This process makes an amazing difference to the smoothness and power output of your engine. It's well worth the investment and they are punctual and professional. Having it done annually would be a good idea.

Adrian was absolutely brilliant from start to finish. His communication was spot-on — friendly, helpful, and professional throughout. He explained everything clearly and made the whole process really easy. The quality of his work is amazing — my car feels incredibly smooth after the carbon clean, like it’s running better than ever. You can tell he really takes pride in what he does.

Highly recommend Adrian to anyone thinking about getting their car carbon cleaned — top guy and excellent service!

Adrian offered a simple and efficient service, from initial contact to completion of the job.

I was booked in quickly and had clear instructions ahead of Adrian’s arrival. He kept me up to date with his ETA on the day.

Adrian showed and explained everything that he was doing, and how the process works. He explained all of the engine codes and diagnostic figures.

Would recommend and will use again in the future

What Causes Carbon Build-Up and Why Your Engine Needs a Carbon Clean

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.

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.

How carbon build-up affects your engine

As carbon gathers inside the engine it becomes harder for it to run cleanly. To keep going it starts using more fuel which increases emissions and creates even more carbon. Over time you may notice:

Poor fuel economy
Rough or uneven running
Slower acceleration
Increased vibration and noise
Higher emissions that may cause MOT failures
Wear on injectors, engine mounts and other moving parts

A carbon-loaded engine simply has to work harder which makes the driving experience feel heavy and less responsive.

Why a 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.

Carbon Cleaning FAQs

Got a question about our Carbon Cleaning service? We’ve answered some of the most common questions we get from vehicle owners across the UK. From how often to book a carbon clean to what results you can expect, here’s everything you need to know before your appointment.

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.
