Engine Carbon Clean system – Does It Really Work?

A few weeks previous to this article, I was approached by a representative of Engine Carbon Clean.com, who wanted to see if I was interested in having their engine carbon clean system performed on my own vehicles to show what results and benefits this process would give. As I’d actually been looking at various engine cleaning systems anyway, I said yes, and now I can deliver the answer to the question; Engine Carbon Clean – does it really work?

Like most, I’m sceptical and wary of anything that’s going to go directly into the engine of my car, so I did as much research as I could on this system beforehand. Note; there are others out there offering an ‘engine carbon clean system’, but the company I’m using is Engine Carbon Clean.com. Their system does not use any chemicals, their gear is CE-certified and all work is fully insured. They are also a Which? Trusted Trader, and all UK agents are participating in a IMI accreditation.

While the system has been designed and manufactured in the UK, the company is global one with agents currently in the USA, Australia, Greece, the Republic of Ireland and Romania. They also work closely with the Ministry of Defence, local councils, commercial fleets and emergency services too.

What they claim

EngineCarbonClean offers what they say is ‘the ultimate engine detox’, using the latest in hydrogen technology to help remove carbon build-up from the engine, with no dismantling of parts and no harmful chemicals used, and they also state that it’s safe and a completely green product.

The main benefits are;

  • Restoration of power and performance
  • Lowers harmful emissions
  • Revitalises fuel efficiency
  • Helps avoid costly repair bills

and other benefits include;

  • smoother performance
  • more responsive power and torque delivery
  • fewer vibrations
  • restored torque
  • enhanced driving experience
  • Quick procedure, undertaken in 30 to 45 minutes by local agent

The system isn’t limited to cars, as it can also be used on motorcycles, commercial vehicles, marine vessels, farm and plant machinery, as well as mining equipment and generators. The local agents carry the equipment on their vans to service engines from 500cc to 13 litres in size, but Engine Carbon Clean have equipment that can be used on engines up to a massive 100 litres in size.

The price

The price varies from country to country, but in the UK it’s GBP £99.00 per car, although there are sometimes offers on if more than one vehicle is booked in at the same time. After the incredible results I saw with both cars, as well as the included diagnostic check, this is an absolute bargain.

How does it work?

To quote the website; The Engine Carbon Clean system works by using tap water to create hydrogen and oxygen which pass through the air intake of an engine and out through the exhaust system as a gas, helping to remove the excess carbon that leads to poor running issues. By removing the carbon, this allows an engine to breathe more easily.

The procedure

Undertaking the work on my cars was my local EngineCarbonClean.com agent, namely Leon, who covers North Lincolnshire and East Yorkshire. From the off, talking to Leon about the system put me at ease as he’s highly professional, friendly and incredibly knowledgeable about the system.

I’d booked two cars in for the engine clean; a 2001 Mitsubishi Shogun 3.5 litre V6 petrol, and a 2002 Lexus RX300 3.0 litre V6 petrol. The Mitsubishi was showing 86,500 miles on the clock, while the Lexus had done around 135,000 miles and both cars have been serviced at regular intervals.

The procedure is quite simple, but I was highly impressed by the thoroughness of the pre-checks carried out before the system is used. First of all, Leon checked all the engine fluids to make sure they were correct, as well as doing a visual check to make sure there are no major leaks or damaged pipes.

The next step was for Leon to plug his laptop into the car’s port and carry out a diagnostics check, which would flag up any potential issues the car had, or which could interfere with the system working. This really impressed me, as simply having a diagnostic check at a garage would cost at least £25 – £35 normally (possibly more at a main dealer) but it’s just part of the Engine Carbon Clean procedure, and should you have any issues show up that need addressing, they can advise whether those are done before the system is used.

Having had the all-clear for both cars, it’s time to start the carbon clean process. This involves a simple loosening of the air intake pipe, and pushing in the pipe which feeds the hydrogen into the system. It’s best if the engine has been warmed up prior to this, as it works more efficiently.

Leon informs me that the hydrogen is not forced into the system, but rather drawn in naturally as the engine is running. As soon as the hydrogen started to be sucked in, the Shogun’s revs rose by a couple of hundred rpm, which is fine according to Leon, as it simply shows it’s working.

The laptop is still attached to the diagnostic port of the car as the process happens, and Leon kept an eye on that as time passes. He then gently and smoothly pushes and releases the accelerator, up a 1,000 rpm or so at first, but gradually doing this until its up a few thousand revs each time. Leon explains that this helps to draw the hydrogen through at a higher rate and allows it to burn off the engine’s carbon build-up at the same time.

One other thing Leon mentioned is that he won’t ‘big-up’ the results to the customer before or during the process, ie; ‘hey its sounding better, the acceleration is smoother’ etc. This is so that they can make up their own minds as to how the engine genuinely sounds, and the true driving effects afterwards, rather than it being a psychological feeling.

I noticed that after around twenty minutes or so, the Shogun’s V6 engine started to sound quieter and smoother, and any slight rattles or judders were almost completely ironed out. At this point, I had a huge grin. While I’d done the research and Leon had explained how it worked, until it actually took effect in front of me I was still naturally a little sceptical.

After around 40 minutes, the process was finished and Leon recommended me taking it for a test run. From the moment I sat and revved engine, there was a clear difference. Previously, there had been a slight juddering or vibrating as the car idled, and there was a small flat spot at lower rpm as it was revved. After the carbon clean, both of these issues were gone, and the engine now revved cleanly and fluidly.

As I got out onto the road and accelerated, I actually started laughing in disbelief at just how much of a positive difference there was to the way the Shogun accelerated. The power and torque was now delivered more strongly and fluidly across the rev range, allowing the physical acceleration to actually feel more polished.

Onto a 60 mph limited road, and the results were just as impressive. The Shogun surged forward in a more vigorous manner than before, so much so that I actually laughed out loud in disbelief at just how much of a significant difference the Engine Carbon Clean had made! Something else I raved to Leon about when I returned was just how much quieter the engine noise was in the cabin too.

With the Lexus, there were similar results. The RX300’s 3.0-litre V6 engine is already incredibly quiet but even then the carbon clean still made a slight difference. However, the main positives that both myself and the other driver noticed were firstly the acceleration was staggeringly better, with the Lexus getting up to motorway speeds way quicker than before. It was also, incredibly, quieter inside too, which I didn’t think was possible with the already-hushed cabin of the Lexus.

The second big difference with the Lexus was the improvement in fuel economy, which we worked out to be a 15 – 20% improvement! With the Shogun, the average mpg also went up by 2 mpg in city driving, and 2 – 3 mpg on a motorway run. That doesn’t sound like much, but when I was previously getting between 16 and 20 mpg, that a good percentage.

Final thoughts

No matter how much someone had enthusiastically explained to me the results you could gain from an Engine Carbon Clean(.com), until I actually physically felt them for myself on two different vehicles, I would have been a little sceptical.

It’s now a few weeks since the clean, and the engines of the Shogun and RX300 feel refreshed and vitalised since the clean. I’m still impressed each time I drive the car by the difference it’s made, and I’ll now be having the EngineCarbonClean.com system done to every car I buy.

    Hi how far do you travel

  3. Jacob

    It works on dry carbon… does it work on oily sludgy carbon build up?

  4. Tom Benson

    Does he power the system from your car’s battery or from the wall (110v/240v)?
