Here are some frequently asked questions:

Q1: What is TerraClean?

TerraClean is a service available via the UK network of approved service centres and mobile operators. A TerraClean service involves linking your vehile to our unique equipment which using highly refined fuels and  patented process will remove carbon and other lacquers which build up in your engine, thus restoring vehicle efficiency, improving MPG and reducing harmful emissions - as well as prolonging the life of various components, thus reducing the costs of ownership.

Q2: What do TerraClean service agents actually do ?

A Service agent will link your vehicle to one of our TerraClean machines (either Petrol or Diesel). The machine will take over as the fuel supply for the vehicle and use a highly refined, none harmful fuel coupled with the patented technology of the equipment to remove the build up of carbon from your vehicle. Many operators also have other TerraClean equipment which can clean and unblock EGR and DPF removing the need for expensive replacement. 

Q3: Is TerraClean any better than the pour-in I have been using for years ?

Yes. TerraClean is unique in the system of cleaning. It is not just about the chemistry, it uses patented technology. TerraClean cleans from Injectors through the combustion process and cleans post combustion too. Thus cleaning EGR & Diesel Particulate Filters. Pour in products are generally very good at cleaning intake and injectors but not post combustion. This applies to other equipment on the marketplace, which claim to clean the system, because they do not employ the same formulation and technology they are only cleaning intake and injection not full system and the all important post combusion parts of the fuel system. 

Q4: How much does a service cost ?

We Randstad are the importers of TerraClean . We set Recommended Retail Prices. Vehicles up to 2.0L engine size £ 110.00 vehicles above 2.0L engine size £ 130.00. Larger engined vehicles including Trucks and Buses will cost more. Your local operator can give you a firm price, before you agree to the service.

Q5: Can you TerraClean any vehicle ?

Yes, we do almost all vehicles. From a Motorcycle, Car, Van, HGV, Bus, Agricultural and Marine engines. There are a few exceptions which we can not do, but your local service agent will confirm when you arrange to book your vehicle in. We have TerraCleaned, commuter motorbikes, family cars, Ferraris, Trucks, Passenger Buses and boats with both outboard and inboard engines.

Q6: Where is my closest TerraClean service agent ?

We continue to develop a network of approved service centres. There is good UK coverage so far. Simply use the “Find a Local TerraClean Service Agent” form for instant full contact details.  See Box on the Right >>>>>>>

Q7: I run a garage, can I become a TerraClean agent ?
We have an application and approval system for prospective Service agents. For more details complete the “Become a TerraClean Service Agent” form by selecting the option – See Right >>>>>>>>>
Q8: My vehicle runs on LPG can it be TerraCleaned ?

Yes. Most cars operating on LPG ran as petrol vehicles before conversion, and build up carbon deposits during that period. A TerraClean will remove those deposits. LPG does not create much carbon so a further service is not usually required.

Q9: I drive a Hybrid, does it need a TerraClean ?
Yes. Hybrid technology and vehicles which use Stop-Go systems to save fuel are inherently prone to carbon build up and will generally develop more carbon deposits than other vehicles with similar mileage.
Q10: When will my car need its first TerraClean service ?
As a general rule we say a car is due a TerraClean after about 15,000 miles. But if most mileage is done about town the service may be better done at a lower mileage, if most mileage is done at motorway speeds then less carbon will have built up and the service will be due at a slightly higher mileage.
Q11: How often do I need to have my vehicle TerraCleaned ?
Read this answer in conjunction with Q10. We generally say you should have your vehicle TerraCleaned every 15,000 miles.
Q12: I have several vehicles to be TerraCleaned. Are discounts available ?

We are the brand importers, manage the network and set Recommended Retail Prices. Individual service agents set their final price and may offer trade or multiple vehicle pricing options.

Q13: What can I do on a routine basis to reduce carbon build up ?
Use of a good quality fuel will help reduce formation of some of the deposits, but the fact is that carbon build up is a natural by product of the combustion process and carbon will therefore naturally develop in a vehicle and build up until removed.
Q14: Will TerraClean damage my Nikasil Seals ?

We have TerraCleaned many vehicles with Nikasil (Nickel Silicon Carbinde) liners. These are found on several brands such as Jaguar, Audi & BMW & current Porsche 911s. TerraCleaned will not cause any damage to the Nikasil coating. We are only using a highly refined fuel, there are no harmful chemicals present .

Q15: Can a TerraClean service damage my vehicle ?

The simple answer is "no". A TerraClean service is using a highly refined fuel which can cause no harm to your vehicle or any of its components. A TerraClean service will remove carbon which has built up over time from your vehicle, as well as other contaminents (tars & lacquers) which build up and deteriorate the performance of your vehicle. TerraClean is not a "fix" for a problem, it is a highly effective preventative maintenance service which will help prevent problems occuring, prolong component life and improve the efficiency of your vehicle in terms of performance, fuel economy and emissions.

Q16: Can TerraClean clean my EGR and DPF system ?

A standard TerraClean will clean through both the vehicles EGR and DPF if there is airflow thruogh these units. BUT, a standard TerraClean service is not designed to unblock these components. There is another tool and service within the TerraClean range which will clean and unblock DPF and EGR. For further details simply speak to your local agent and explain your problem. 

Q17: Will TerraClean work with my petrol Direct Injection engine.

A standard TerraClean service does not touch the Intake on a DI engine. But there is an adaptor tool the service agent can use to clean Intake and there is a specific Petrol Induction tool whcih many of our agents have specifically designed to clean this part of a Direct Injection system. Simply talk to the agent when booking the car in about your requirements.
