Advanced Engine Decarbonising.

TerraClean is an advanced decarbonising solution designed for today's high-compression, multi-valve and direct-injection petrol and diesel engines.

TerraClean Thame

Cleaner Combustion. Better Efficiency. Stronger Performance.

TerraClean is designed to reduce carbon deposits inside the engine and fuel system. By tackling build-up created during combustion, the treatment aims to help restore lost MPG, lower emissions and recover vehicle performance.

Restore Performance Carbon reduction can help an engine recover lost response.
Improve Fuel Economy Cleaner combustion may help the engine operate more efficiently.
Reduce Emissions Improved combustion efficiency can support cleaner operation.

Inside the Engine Carbon Build-Up
What Is Carbon Build-Up?

A Natural By-Product of Combustion.

Carbon deposits are produced naturally during combustion. Over time, those deposits can accumulate inside the engine and affect how efficiently it operates.

The result can include reduced performance, poorer fuel economy and increased emissions.

  • Reduced engine response
  • Lower fuel economy
  • Increased emissions
  • Reduced overall efficiency
Fuel Economy Claim 4–15% potential improvement through proper decarbonising
Keep Your Engine Properly Decarbonised

Good Maintenance Goes Beyond a Single Treatment.

The original TerraClean information states that keeping an engine properly decarbonised can improve fuel economy by around 4–15%.

It also highlights the importance of fixing underlying faults. For example, a faulty oxygen sensor can have a much larger impact on fuel economy than carbon build-up alone.

Actual results vary by vehicle condition, engine type, driving conditions and existing mechanical faults.

The TerraClean Story

A Decarbonising Technology Discovered by Accident.

TerraClean originated from research by a group of environmentally conscious Canadian physicists who were attempting to develop an ultra-low-emission internal combustion engine.

Their test vehicles were fitted with a molecular injector and effectively operated the TerraClean system as part of the vehicle's fuel system.

When technicians later dismantled the test vehicles, they found very little evidence of carbon build-up.

Unsure whether this was simply due to the age of those vehicles, the same technology was applied to an older engine known to contain accumulated deposits.

After running the process and dismantling the engine again, the carbon that had accumulated over years of use was found to have been removed.

The cleaning effect worked — but operating a vehicle permanently using the system was too expensive to be commercially practical.

That led researchers to reverse-engineer the process and understand exactly why it cleaned the engine.

The technology was then developed specifically as a decarbonising solution capable of cleaning the engine and the wider fuel system.

Why TerraClean?

Designed for Modern Engine Technology.

TerraClean is particularly suited to modern high-compression, multi-valve and direct-injection engines where carbon build-up can gradually affect performance and efficiency.

The aim is not to replace routine maintenance, but to complement good vehicle care by addressing deposits within the combustion and fuel systems.
