What is revitalization?
The term "revitalization" (from Latin "vita" life) literally means "returning to life". The discovery of the revitalization phenomenon is based on unique physical-chemical processes occurring under certain conditions in the friction zone. XADO contains a building material and a unique energy activator which uses excess friction energy to create a new surface. The process of revitalization stops as soon as the part (or parts) restores its geometry. Revitalization provides individual adjustment of mating parts, and all rubbing surfaces appear to be covered with not quite clear glass.

How big can the build-up be?
XADO revitalizants will add the very necessary microns to the worn pump element, "hundredths" to the engine parts, and "tenths" to the cog wheels. This is REPAIR.

What are the properties of this coating?
XADO coating is very hard, quite smooth, and corrosion resistant. It has a micro hardness of 650750 kg/square millimetre. Surface roughness of the most of new parts is between 0.9 and 2.1 Ra while XADO assures you a surface roughness of 0.06 Ra.

Could the cermet layer growth cause engine seizure?
No, it could not. The process of revitalization is a self-regulating one. It is the most active in the places of the extreme wear where there are all necessary conditions for the cermet coating growth: high temperature, extreme pressure, much friction. As soon as the surface is reconditioned and cermet coating is formed, the process stops as there are no reasons for the further growth.

I have a new automobile. Why do I need XADO?
The run-in period is a time of adjustment of the parts. During this period the surface layer of the parts wears out. XADO revitalizants allow going through run-in with minimal loss, and offer the unique opportunity to protect and tune the parts covering them with the cermet coating.

I just had a major overhaul done, do I need XADO?
XADO Revitalization is especially vital for engines that have been overhauled. During a regular overhaul it's impossible to ensure the original hardness of the parts surface layer. XADO can recondition the parts and restore surface hardness.

Will the cermet layer peel off during running?
No, it will not. The diffusion (not adhesion) of metal and revitalizant results in a monolithic and solid crystal buildup to the depth of 10 to 30 m. Therefore, there is no clear border between the matrix surface and the cermet layer.

Why does the amount of gel applied depend on the volume of oil but not on the wear degree?
The amount of oil in the engine & other joints & units is proportional to the area of the operating surfaces. One should take into account the volume of oil system because the calculated amount of gel is sufficient to restore any wear degree.

Which kind of oil is the best for treatment, mineral or synthetic?
It makes no difference because the revitalizant is compatible with any kind of oil and fuel. It does not react with them and does not change their viscosity. The oil only carries revitalizant to friction surfaces. XADO is not for oil, it is for repair.

Should the oil be changed before the engine treatment?
Only if oil resources are not sufficient for full cycle of revitalization.

Does XADO settle in the crank-case if the car is parked for a long time?
No, it does not if you follow the directions when applying XADO. XADO should only be applied to a warmed engine. The engine should then be run for at least two minutes at idle. This allows the revitalizant to localize on the friction surfaces.

Should I add XADO after each oil change?
No. The coating is formed during the first 9301,240 miles (1,5002,000 km) of running. After treatment you may change oil as usual. "XADO effect" remains after several oil changes (up to ten).

How does XADO help to save fuel?
As a rule, excessive fuel consumption is caused by wear of the cylinder-piston group. After revitalization the geometry of the parts is restored, & fuel consumption returns to normal. In addition, a lower friction factor (surface roughness 0.06 Ra instead of the usual 0.9 to 2.1 Ra) significantly reduces friction losses. As a result you can save up to 30 % of fuel at idle & 57% of fuel when driving.

Can I treat a two-stroke engine?
There is a special compound, gel for reconditioning the cylinders in two-stroke engines. It can be used for treating any mechanisms from scooters to lawn-mowers and chain-saws.

Can valve guide rods be reconditioned?
Valves are protected with special oil-scraper cups (valve seals), so the amount of oil getting onto the valves and, respectively, of revitalizant, is really slight. If the valves wear is small, this is sufficient to protect and preserve the valves. If the wear is extreme, it is necessary to replace the valves and the guide sleeves.

How long will the coating obtained last?
Say the compression in the cylinder before treatment was 142.2 psi (10 kgf/cm2) and after treatment, it became 184.9 psi (13 kgf/cm2). The manufacturer guarantees that this performance will remain the same for a year at any mileage. In practice, your car can run 60,000 miles without loss of improved performance (100,000 km). Then, you can treat your engine again.

Can all compressors be treated by XADO technology?
Yes, practically all compressors can be treated by XADO technology. The benefits of the treatment are: increase of oil pressure, elimination of clearances in the crank gear; elimination of ovality and obliquity in the cylinder-piston group and reconditioning of worn surfaces up to 0.5 mm. The oxygen compressors cannot be treated by XADO because of absence of oil.

What should I do when it is difficult to remove spent grease?
In this case, it is recommended to use the "Repairing" Grease. Add it directly to the regular grease. The high concentration of revitalizant in "Repairing" Grease makes it possible to restore the extreme worn parts up to their original sizes and ensures a practically unlimited service period later on. All OADI Greases are mutually compatible.

How to revitalize joints and units operating on greases?
By replacing the regular grease with XADO Greases. First you should diagnose the joint wear degree. Choose the right XADO Grease: 1. "Protective" Grease is used in new joints and units, or in those with insignificant wear (up to 10%). It is a universal substitute for any grease. 2. "Restoring" Grease contains more active components. It not only protects parts but restores their geometry as well. It is used in joints and units with wear degree up to 50 %. 3. "Repairing" Grease is used in joints and units with wear degree up to 80 %.

We have a lot of machine tools. What would be the benefits of XADO treatment?
A machine tool is rather complex mechanism. Naturally XADO revitalization improves all its performances. For example, spindle, the main part of any machine tool, operates at high speed and under heavy loads. It wears considerably and quickly. Professionals know that it will take a lot of time and efforts to repair a machine tool. The high-speed XADO Greases will protect and recondition the parts of your machine tool.

Is the cermet layer formed on non-ferrous metals?
Yes, a cermet layer is formed on all "metal-metal" friction pairs, including non-ferrous metals and any alloys.

I have seen some ads about revitalizants for rifled barrels. Is it of XADO too?
Yes. XADO revitalizant for rifled barrels is one of our new products. It is especially designed for restoring and protection of barrel bore. It ensures the following benefits: l reconditioning and repair of inner barrel surface; l improved accuracy of hits; l ten times increased wear resistance and endurance of the barrel; l maximum killing power for given ammunition; l flatter trajectory; l more spin.

Does the barrel need any preparation before revitalization?
No special preparation is required. A regular cleaning of the bore is enough.

What is the breaking point at which XADO will fail to restore the barrel?
The OADI revitalizant improves the firing performance of arms at any wear degree.

What is the service life of a reconditioned barrel?
A special experiment was needed to answer this question. XADO revitalizant for barrels of rifled arms has passed very severe tests in "Rzhevka" certified test laboratory of fire-arms. The results of the revitalizant were examined on different arms, new and worn-out, on both chrome and non-chrome barrels. The experts conclusion was specific: XADO revitalizant has the ability to remarkably improve the accuracy of any rifled arms. In one powerfully convincing test a brand new SKS rifle was treated with XADO. You would think that nothing could be improved in a new such rifle. But after the treatment, the accuracy of hits improved by 23%. Then 200 consecutive shots were fired. The barrel became so hot that the varnish on the forearm began to melt. It was cooled in a brutal manner plunged in a bucket of water. The witnesses were all anxious about the results of such an experiment. Even after this abuse the radius of the group of shots was reduced by a surprising 46.6 %. The service life tests carried out at Rzhevsk allow us to claim that the service life is 10,000 shots with no loss of improved performance. Under normal loads, youll be able to keep the barrel in an ideal condition at all times by treating it once a year with the green gel (10 shots) or fire 10 times using the same gel after every 1,000 shots.

Does the treated barrel need any maintenance?
No special maintenance is required. Moreover, the protected inner surface of the barrel is more corrosion resistant than conventional coatings.

Does it make any difference whether the barrel is chrome or non-chrome?
The revitalizant improves the shooting performances of a barrel with any coatings, both chrome and non-chrome.

I have a smooth-bore gun with a pit in the chrome coating. Will XADO help?
Yes, it will. The main point is to observe the revitalization principle, i.e. to ensure sufficient friction between the bullet and barrel surface. For this, you might want a bullet of special design. In this field we have the special experience and practical skills of both our experts and firearms fans. For more detail, do not hesitate to contact XADO.

Is XADO toxic?
No. All our products have a sanitary permit for usage in the food industry and a hygienic certificate.

My car failed NCT on emissions, told i need new catalyst converter, any of your products help with this?
In short the answer is yes.
XADO can resolve the cause of your problem, but it can not repair your catalytic converter, failure of the catalytic converter is the result of your engine burning oil. Xado will require approximately 1000km to complete treatment and resolve the issue of the engine burning oil, your car will then require a further 500km to clear the fouled catalytic converter. It is only at this time you will discover whether or not your catalytic converter is in fact irreversibly damaged.

Let's get the picture more detailed.
When an engine is worn due to high mileage, poor maintenance and or abuse, it is common for the engine to then burn oil as a result of engine oil entering the combustion chamber due to the degradation of the seal between the piston and cylinder walls provided by the piston rings. XADO Gel-Revitalizant can and will restore this seal by rebuilding and hardening the cylinder walls which become oval with wear. This will prevent the engine burning oil and drastically reduce emissions problems, the catalytic converter was not designed to deal with oil in the exhaust fumes. It should be understood, that even if XADO is used to resolve this problem your catalytic converter may already be irreversibly damaged by oil vapors. It is impossible to know without first attempting treatment with XADO Gel-Revitalizant.
