Questions & Answers


A Sequential Turbocharger System is a set up where the engine uses combined turbochargers in one unit, as used on some Land Rover/Range Rover, BMW, Ford, Jaguar and Mazda models. This technology is becoming more common on larger capacity engines and will no doubt become a common configuration in the future.
Due to the complexity of its design, when treating these systems with REVIVE, it is necessary to use a vacuum pump to operate the actuator valves which open the transfer chambers, allowing the REVIVE fluid to pass through the complete system. Otherwise, only the smaller primary turbocharger would get treated, bypassing the secondary or main turbo. Because of this, treating these systems should be left to qualified professionals.


Is REVIVE a Fuel Additive?

No, unlike additives that get poured into the fuel tank, Revive is a treatment which is injected into the engine air intake when the vehicle is running and once treated and taken for a drive, the results speak for themselves.

What if my engine has 2 Turbo’s?

The application rate and treatment dose can be understood by using our Treatment Calculator. It depends on the Cubic Capacity of the engine, the Red Line limit and whether it is fitted with single/twin Turbochargers and inlet configuration. It also depends on whether the two turbochargers are seperate (one each bank) or whether it is using a Sequential Bi-Turbo Set up. In these cases, please refer to the Sequential Turbo FAQ and seek professional advice.

What Symptoms Will I See?

As a driver you may see any combination of the following: Smoking exhaust. Engine warning lights and messages 'Check Engine'. Increased fuel usage. Failed MOT emissions test. Poor performance / pickup. Limp home mode.

(Limp home mode - the computers that control the engine can restrict how fast it runs and how much power you get from it, often occurring whilst overtaking. This lets you get your car to a garage without causing more damage, you will also see the 'Check Engine' light)

Can I treat my own engine or do I have to take it to a Garage/Workshop?

Revive was formulated as a low cost solution to a global problem and was intended to be used by Trade Professionals. Although the treatment process is very simplistic, diagnosis of the problem or issue isn’t so simple. Once accurately diagnosed and treated, it is quite likely that fault codes are generated because of the process and diagnostic equipment will be required to clear them. Depending on the strategy of the ECU (Engine Control Unit) and the Vehicle Manufacturer, these should clear after 3 ignition cycles. If the Mass Air Flow sensor was disconnected with the ignition on (there is no need to!) then diagnostic equipment will be required to clear the code generated.

Will Revive clean Inlet Valves of Direct Injection Petrol or Gasoline engines?

Because fuel is injected directly into the combustion chamber, Direct Injection Petrol or Gasoline engines (GDI) suffer from carbon deposit build-up on the back of the inlet valves, due to no ‘fuel backwash’ through the inlet stem. These deposits restrict the air path, causing the engine to run rich. If Revive is used regularly as a preventative maintenance treatment, it will minimise this build-up. However, if untreated and the build-up is severe, an alternative cleaning process may be required.

Will Revive clean the intake side of the engine (inlet manifold, intercooler etc.)?

Revive will start cleaning as soon as it enters the air intake pipe. It will clean the oily deposits generated by the crankcase ventilation system from the throttle body to the inlet valves. Revive will clean the surface area that it passes, including, inlet manifolds, swirl flaps and intercooler. However, we have all seen inlet manifolds that are so badly clogged up; you have to ‘spoon’ the carbon out, in these cases, removing the inlet manifold and manually cleaning it, is the only option.

How can the fluid still be effective after combustion?

Unlike flammable propellants, which combust and are spent by the time they reach the hot side of the turbo (turbine), Revive’s patented non combustible formula, survives the burn process and the ingredients are still active passing through the exhaust valves and turbocharger, ensuring an effective clean of the variable vane mechanism.

It made a big difference but it’s not perfect.

If an engine is particularly dirty, then a second treatment is beneficial. If the second treatment is carried out soon after the first, we would recommend an oil change after both. We would also recommend to scan and clear any fault codes.

Why has the engine got to be cold?

Due to Revive being Aqueous based, it is inevitable that a percentage of the fluid will evaporate, due to the extreme temperatures if the treatment is carried out on a hot engine. So treating a cold engine maximises the effectiveness of the 750ml bottle.

Will it cause ‘Hydrolock’?

If applied as per instructions, then there is no chance of Hydrolock because the treatment process is calculated to administer the fluid through the combustion process in measured quantities over a specific period of time and at specific RPM ranges.

Will the treatment process block my DPF?

It is important to understand that, whilst there is a Diagnostic Trouble Code (DTC) in the Engine Control Unit (ECU), other than DPF related codes, the strategy of the ECU will abort any attempt to naturally regenerate the DPF until that the cause has been rectified, such as Turbo Overboost / Underboost conditions. During this period, if ignored, the Pressure Differential Sensor will detect an increase in soot content and this will continue to rise if driven and will trigger a DTC relating to DPF blockage even before a Revive treatment. When treating your vehicle, Revive will remove soot and carbon deposits from internal components, so it is inevitable that the removed particles will add to the soot levels in the DPF. Once the DTC’s have been cleared, the Engine ECU will then reinitialise the regeneration process, lowering the soot levels and this explains why customers believe that Revive has cleaned the DPF.

How Does It Work?

Revive is a Non-Ionic Surfactant and when applied at velocity through the combustion process, removes surface layers of soot and carbon deposits in tiny particles, which are no larger than the soot particles the engine naturally generates.

Will Revive clean the EGR Valve?

It depends on where the EGR Valve is located in the system; it also depends on whether it is open, as Revive needs to pass by the component to be effective. If the EGR is totally clogged with carbon, then it needs to be removed and cleaned manually with an aggressive solvent based cleaner or ultrasonically.

Will Revive Fix The Problem?

It depends on the cause of the problem, if it's soot build-up related, then Revive has a very good record of helping. Your Garage may recommend trying Revive first, rather than going down a more expensive repair route. If the build-up is very bad, you may need to apply two treatments. Prior to making a purchase, please carry out some basic tests first. Using suitable equipment, check for vacuum leaks in related pipes, solenoids and actuators. Scan for diagnostic trouble codes to identify the fault area. If you are unsure, seek advice from a Qualified Trade Professional. Revive is extremely effective at removing sooty carbon deposits from Variable Geometry Turbochargers, however, it cannot compensate for split vacuum pipes, mechanically worn or seized components. - Check out Revive's Reviews & Real world use

Will Revive harm any part of the engine?

The short answer is “no”....

The quality is rigorously controlled, with each and every batch of fluid being put through a series of tests to ensure that the mix is correct and that nothing has got into the batch that could cause any harm to any of the metals or seals in the engine. The tests are pH level, alkaline metal content, chlorides, specific gravity and the freeze point.

The fluid is non flammable, has no oxidising properties and is neither acid or alkali. It is also non-toxic.

The product is a variant of a cleaning fluid that is used for Rolls Royce and other aero engines. It is also used in the gas turbines that drive some of the world’s largest power stations, and as such is manufactured to the very highest standards.

Since the product was first used in 1987 there have never been any reports of it causing any damage to an engine.

What are Revive Service Cleans?

Preventative Revive cleans are performed each time you have your vehicle serviced by your garage or mechanic. These help keep your engine running as it was designed, fuel economy and performance up and may prevent the inconvenience of an expensive repair.

Why are Turbo Problems so Expensive?

Turbos are high precision parts and are often put in hard to reach places, this takes the mechanic more time to remove and reinstall and makes replacing an already expensive turbo a very costly job. This is why a Revive clean is often the first thing recommended to try and solve the problem without the expense.

What are Variable Geometry Turbos?

More and more diesel vehicles have very efficient turbos fitted to them called Variable Geometry / Nozzle / Vane Turbos. These change how the dirty exhaust gas gets directed inside the turbocharger as you drive. These movable parts are very prone to getting clogged up and stuck, then failing to work properly, causing reduced power, poor drivability / pickup and 'Check Engine' warnings on the dashboard. Diesel turbo cleaning performed with Revive can help prevent and cure these problems.

Are Diesels Worse Than Petrol?

Yes, because diesel engines produce more particles of soot than a petrol engine, there is a far higher chance of your engine suffering carbon/soot build-up.

Can I Prevent Soot Build-up?

Yes, a Revive maintenance clean at each service will help prevent oil and soot building up in the first place and may stop the need for costly repair work in the future.

Why do Engines Need Cleaning?

Despite recent improvements in engine efficiency the fuel is still not 100% burnt, this can be seen as soot deposits in the end of the exhaust pipe. This same soot also collects in various hidden places around the engine's system.

Modern engine designs need more parts to deal with environmental and fuel economy demands put on vehicles. These same parts are prone to failure due to the build-up of deposits. Once they get stuck or blocked the part can not operate as it was designed to and can cause various different symptoms.
