What is engine carbon cleaning and is it worth the money?

It’s hard to be at your best when you’re all blocked up, isn’t it? We feel tired, sluggish, defeated – and it’s no different for your vehicle, either.

Instead of performing on all cylinders, your vehicle loses its power, costing a fortune in fuel as it leaves a trail of harmful smog from one journey to the next.

If this sounds horribly familiar, it might be the case that your vehicle is suffering the strain of carbon deposits blocking its engine.

And if that’s the case, you’d better read this before things get worse.

What is engine carbon cleaning?

It’s the process of improving your vehicle’s performance and efficiency by removing unburnt hydrocarbons from its engine and various other combustion components.

Depending on the severity of soot built up in your vehicle, your mechanic will use a quick and simple hydrogen system to remove blockages, but in more extreme cases, individual components may need to be dismantled and hand cleaned, otherwise known as ‘decoking’.

Why do you need an engine carbon clean?

Despite introducing emission control devices, such as catalysts and diesel particulate filters, all vehicles (especially diesel and vintage engines) tend to collate carbon deposits as a by-product of burning fuel.

Over time, these deposits start to clog engines and combustion systems, leaving a noticeable decline in a vehicle’s performance, responsiveness and efficiency.

Modern petrol vehicles with onboard fuel-efficiency technology are far less likely to experience the same amount of clogging as a diesel engine, where the fuel tends not to burn as cleanly, resulting in excessive deposits of tar and soot.

In extreme cases, excessive blockages in the engine and combustion components can lead to an MOT failure due to high emission readings.

How does engine carbon cleaning work?

At CR Allen & Sons, we feed a hydrogen-based system into the air intake of your engine, where it begins to break down carbon build-up quickly.

And because our system only uses natural cleaning agents, it doesn’t run the risk of eroding any vehicle components notorious with other chemical-based carbon cleaning methods.

With our engine carbon cleaning service, we’ll clean your:

  • pistons
  • valves
  • cylinder heads
  • injector nozzles
  • exhaust manifold
  • exhaust gas recirculation (EGR)

What’s more, our safe and speedy system requires no stripping or dismantling of parts and can be completed in as little as 45 minutes.

For more severe cases, we also offer an advanced polymer bead blasting service, a technique whereby fine glass beads are directed under high pressure to remove surface deposits.

How do I know if I need an engine carbon clean?

Clear warning signs you may need an engine carbon clean is a lack in performance, illuminated warning lights, or, in extreme cases, a failed MOT due to high emissions.

Your mechanic will be able to diagnose and advise further during a routine vehicle health check, service or MOT.

What are the benefits of engine carbon cleaning?

As well as extending the life of your vehicle, an engine carbon clean can also help to:

  • restore responsiveness
  • revitalise fuel efficiency
  • restore performance
  • lower emissions
  • restore power
  • reduce engine noise

If you want to make sure your vehicle is ticking all of these boxes, book a health check with our advisors today.

How much does engine carbon cleaning cost?

Our service costs £48 inc. VAT or FREE when you use our remapping service.

We’re nice like that.

What can you do to delay engine carbon cleaning?

Easy ways to keep carbon cleaning at bay include staying on top of your servicing schedule, as well as using high-quality oil, fuel and filters.

If you tend to take short journeys in your vehicle (anywhere under 10 minutes), it’s a good idea to take the longer route once in a while to give your engine a chance to warm up properly and expel carbon particles.
