The key features of the part’s surface before and after revitalization are as follows: increase in micro hardness (kg/micro metre2) from 65-280 to 650-750 range, after treatment; the roughness coefficient (Ra) before revitalization was 0.9-2.1, and after treatment it is 0.06; and above all a dramatic increase in corrosion-resistance characteristics.

During the first few miles when a new vehicle is being run-in, adjustment of friction surfaces takes place. Revitalization allows the vehicle to be run-in with the minimal of material wear, and offers the unique chance of preserving the entire machinery. The surface does not wear out because it is protected with a cermet coating, which is more durable than metal surface matrix. It will be the new cermet protective layer that will be subject to wear and tear, not the original metal surface. Note that during revitalization, the friction surfaces adjust to one another individually, this is only possible during manual assembly. This means you will receive a custom fitted engine in your vehicle!

Revitalising is critical for engines that have been overhauled because during typical overhaul you cannot repeat the steps the original surface hardening. When boring an engine, the upper layer that is especially hardened is removed. And, if prior to first boring, the engine was running for about 200,000 km on average, then after the major overhaul this figure will fall to 70,000 km. This would ultimately happen if you do not use our XADO treatment. XADO will harden the surface for you!

The treatment again depends upon the amount of oil in the engine-and-gearbox unit (see question above). If you have used any of the engine treatments, which includes the three stage blister packs, the advanced 1 stage products or the 1 stage metal conditioners This varies from 1 blister pack treatment up to 9 blister packs for larger engines. The treatment for an average petrol or diesel saloon car with an oil capacity of 3 to 10 litres, is 3 blister packs. Don't worry this is NOT required immediately but, these will last for 100,000 Kilometres (65,000 miles). We are one of the only product that will last so long, unlike other products that require you to repeat the process every 20,000 miles!

XADO would certainly help; not least it will protect your engine against any future problems.  Even if you think there is no existing problem with your engine, there will always be minor areas or wear that XADO will restore. View XADO as an insurance policy.

It is widely agreed that the crosshatch finish on a cylinder wall is vital to help retain oil on the cylinder wall surface.

The application of XADO has no effect on the lubrication of the cylinder surface as the cermet coating is olephelic, (oh-lee-oh-fil-ik), meaning the coating attracts oil.  The olephelic nature of the cermet coating not only retains oil, but also significantly reduces friction between the piston rings and the cylinder walls.

In fact by using XADO you will help to refine the bore Geometry?

No, the engine will not seize. Revitalizing is self-regulating. In fact, the formation of a cermet layer takes place in both friction surfaces that are affected by the same load. due to the high pressure and temperature, a cermet layer starts to form between the friction surfaces. Its thickness increases pro rata to the wear (the process was explained in the answer to question 1). As soon as the original worn surface has been repaired, the friction factor drops dramatically, and the XADO activation energy will also decrease. The process then stabilizes, and at some point, the energy will drop to a point where cermet growth will stop completely.

The gel when added to the oil completely breaks down It passes through the filter with the oil.

No, XADO will not affect the turbo or catalytic converter. It will not harm them in any way.

There are many causes of reduced oil pressure, ranging from trivial failure of the oil sensor to a worn out oil pump, bushings, or crankshaft journals. If the wear is not catastrophic (not 100 %), XADO will definitely help! In any case, consult a certified technician. 

The causes of excess oil consumption are numerous. Some of them are easy to eliminate, while others present a serious problem. If the problem is due to the extreme wear of the sleeve assembly, XADO can help, but even here, the degree of wear is a key factor. Let us remind you of manufacturers’ recommendations: consumption of 1 litre of oil per 1,000 km (for a petrol engine) points to practically 100 % wear, so a good mechanical diagnostics is always necessary.

As a rule, excessive fuel consumption is caused by worn sleeve assemblies. After revitalization, the assembly geometry will be restored, and fuel consumption will be restored to its original value. In addition, a lower friction factor (surface finish 0.06 Ra instead of the usual 0.9 to 2.1 Ra) will significantly reduces friction loss. The result is a dramatic increase in fuel savings, up to 30 % at idle and 5 to 7 % when driving. 

By restoring the cylinders’ geometry, compression grows by 10 to 20 % as early as in the first 500 to 1,000 km of operation. We have witnessed cases when the compression increased from 4 - 6 atmospheres to 10 - 12 atmospheres. Usually, low compression values are caused by mechanical damage (piston burnout, valves, etc.), rather than by natural wear.

Of course, to be on the safe side the engine should be re-bored! Keep in mind that the cermet layer is formed to a depth of 10 to 30 micro metre, whereas the cutter removes a much greater layer of metal. But do you really need conventional major overhaul? The exceptional capacity that enables XADO technology to restore the geometry of engine parts will allow you to avoid these labour-intensive and expensive repairs. For instance, the repair of the sleeve assembly can be reduced to replacing damaged piston rings or replacing rings that have completely lost elasticity, replacing a burnt-out piston, etc. In other words, you would only need a “face-lift” repair, which takes only a few hours.

Try using XADO engine blister pack or the single 1 Stage Advanced engine treatment, which comes, in a tube or as a metal conditioner.

Try one of our engine revitalizants. We have had many customers used our products to pass an MOT. Of course it depends on state of your engine, but there is no harm in trying.

One blister pack will certainly help but it will not complete the process of full revitalization. There is no harm in trying and you can always order additional blister packs as and when you want to.

Yes, XADO can be used with any vehicle no matter its age. We have many classic car owners who use XADO.

Yes, XADO will work in all engines. If the engine is in reasonable condition, but in need of some revitalization the product will work. If the engine is excessively worn it will still work but the results will be less noticeable, and would be best accompanied by any necessary mechanical repairs.

Yes XADO will help.  We have our revitalizant designed to treat gearboxes and differentials.

Yes XADO will work on a Nikisil coated engine, and no it will not strip the bore lining of it’s original Nikisil coating?  We have experienced with this coating as well as other similar coatings and XADO works well.

Yes XADO can be used in any engine whether it has a dry or wet sump.

Noisy tappets can be due to inaccurate tappet adjustment so this may need to be adjusted manually.  If there is some wear and tear on the metal surface then XADO will help.  Again, try it and see if it helps, it will do not harm.

Use the XADO for small engines and this will treat both the engine and the gearbox.

You can use XADO to treat all types of engines.  There is a special gel for revitalizing two stroke engines whether it is a motor cycle, scooter, chain saw, outboard engine, in fact any two stoke engine.

Of course, you can. The XADO technology is compatible with all additives, metal conditioners, and re-metalisants, no matter how often they were used.

No, XADO does not contain any of these products.  These products can damage your engine and in certain circumstances are toxic and carcinogenic. XADO is very safe to use.

No XADO is not an EPA as EPA’s traditionally contain sulfur or chlorine compounds which can react with water and combustion by products, forming acids that facilitate corrosion of the engine parts and bearings. As you have seen form our website XADO causes none of these.

The gel revitalazant in tubes are our original products and though easy to use, it can be difficult to use on some engines, gearboxes etc, where the oil filler neck or plug is in a difficult to reach location, so we designed the aerosol. This comes with a convenient tube, which you attach to the aerosol nozzle allowing you to reach these in accessible places.

The metal conditioners contain exactly the same revitalizants that is in all our products, except they have two additional enhancements. The first is what we call a 2D sliding agent, which provides additional anti friction properties. The second helps to enhance the lubricating properties of your oil by strengthen the oils lubricating capacity.

No, XADO will not damage your engine. XADO revitalizant in gel aerosol or granular form are completely soluble in the oil and do not change the viscosity of the properties of the oil in any way. Remember XADO is self-regulating. As soon as the original worn surface has been repaired, the friction factor drops dramatically, and the XADO activation energy will also decrease. The process then stabilizes, and at some point, the energy will drop to a point where cermet growth will stop completely. Besides, using too much is just a waste of money.

No, you do not need to flush your engine as part of the revitization process XADO cleans the metallic surfaces. However if you do feel your engine needs flushing, try our Vitaflush product, which will not only flush the engine but will also restore it.

Mix the contents of the tube with a small amount of oil warmed up to room temperature. You can then pour this don the oil filler neck.

You can use XADO in either case, but for the full treatment to take place you must not change the oil until 1,500 km after using the treatment.  For some of our treatments this may be less depending on the product you are using.

Yes, XADO will help protect the vehicle engines and keep your customers happy. We have many new car sales rooms and second hand car dealers who use our products. Look upon XADO as an insurance premium, it will protect your engine against any unforeseen issues that you may not be aware of. It is better to be safe than sorry!

If you can provide relevant information to authenticate that you are a member of the trade, we are happy to offer trade discounts.

Here the rules are the same as for any other lubricant. First, remove the old standard grease, and then apply the new grease. Do not completely fill the inner bearing body with grease - this is a common error. Excess grease in a bearing is, in fact, provides an additional load which cause overheating and will accelerate wear. Refer to manufacturer’s suggested amount of grease that can be applied. XADO grease can be used for the entire service period of the bearing (or other assembly), and requires no subsequent replacing.

In principle, this is possible, but when revitalizing a bearing assembly in the standard way, the acting surfaces are adjusted independently to one another. However, if revitalization is performed on a bench (let’s call this method an artificial one), then after the bearing has been refitted, it may be that the bearing will not run with the reconditioned friction surfaces.

A machine tool is a complex piece of equipment, but it is still a mechanism, so naturally, revitalization improves its performance. We would like to draw your attention to the extreme effectiveness of XADO for high-precision machine tools. The spindle is the key component of any machine tool. It is a highly loaded assembly running at high speeds (up to 30,000 rpm, and in coordinate grinding machines the speed even reaches 84,000 rpm). This leads to significant wear in a very short time period. Experts know that conventional repair of such assemblies is, in many cases, impossible because of the specificity, complexity and shortage of parts. Here is where XADO comes handy! Revitalization with one of the special high-speed XADO greases allows the spindle operations to achieve the required certification. Rejects are practically eliminated, this being of critical importance during any finishing operations.

Yes XADO can be used to reitalize the engine in standard diesel locomotive engines, but if the locomotive is the new generation of electic engines you can still use XADO greases to lubricate the wheels and couplings etc.

Yes whether it be added to the engine oil or a grease to lubricte any rotary couplings.

Again XADO can be used in any oil lubricated engine. The application process is the same as any vehicle engine but in larger marine diesel engines the quantity of XADO required will of course be greater and will be calculated on the quantity of oil lubricating the engine. Of course you can also use XADO in your marine gearbox.  If you need advice as to the amount required, plese call us so we can help.

Yes, XADO technology will recondition any mechanisms, simple, complex, small and big, ranging from watches to nuclear power plant turbines – wherever where there is motion and friction. For a clear, effective and fast demonstration of the effectiveness of the technology, there is no better example than a “projectile & barrel”. Here is an ideal example where all the conditions required for the formation of the CERMET coating are in place, namely a very high temperature, significant friction energy and interaction of materials with different strengths. The revitalization process takes place literally in front of your eyes. The Russian certified handgun test laboratory “Rzhevka” military unit 33491, in association with “Kalashnikov. Firearms. Ammunition and Equipment Magazine” carried out extensive tests. The tested included both new and used firearms with chromed and non-chromed barrels.

Revitalising a rifle barrel provides the following: geometry restoration (complete shuttering) and protection from the wear of the bore surface; maximum impact force for the given type of ammunition; a 10-fold increase in wear resistance and barrel life; an increase in firing flatness, the key factor is a 2 to 3 fold increase in firing accuracy!

No special preparation is needed. Standard cleaning of the bore is enough.

The XADO revitalizant improves the firing performance of any firearm however worn.

A special experiment was needed to answer this question. First, a new chrome barrel was revitalized. Even though the barrel spread characteristics, complied with the standard acceptable, the firing accuracy increased by 23 % after treatment with XADO!

Next, the durability tests were conducted. This meant firing 200 tracer rounds in succession. The firearm became so sizzling hot that the stock varnish coating began to run. It was cooled in the simplest way by dipping it into a bucket of water. Everybody waited impatiently for the results of the test. Sceptics wagered that the coating wouldn’t withstand the extreme temperature drops and would simply peel off. The results surprised even the developers of XADO! The firing accuracy increased by an additional 46.6 %!  The service life tests carried out at the Rzhevsk test facility allow us to claim that the service life is 10,000 shots with no loss of improved performance. Under normal loads, you’ll be able to keep the barrel in an ideal condition at all times by treating it once a year with the appropriate XADO treatment.

No special maintenance is required. Moreover, the protected inner surface of the barrel is subject less to corrosion attack than conventional coatings are. Remember that chippings and micro cracks are restored even on chromed barrel coatings!

No, it won’t. Special barrel rusting and exposure tests have shown that the performance of a treated barrel does not degrade.

The revitalizant improves the accuracy of any barrel, both chromed, and un chromed.

After revitalization, shooting accuracy, even for high-precision barrels, will certainly increase.

Yes, it will. The main point is to observe the revitalization principle, i.e. to ensure sufficient friction by contact between the bullet and barrel surface. You might want to use a bullet of a special design. In which case, you can draw more extensive conclusions and back up both of our tests.

All engine oils and greases have some form of additives added by the manufacturer. In fact without these additives the oils and greases would not do their jobs properly, so it is a fallacy that there are no additives in any of oils and grease and that you should not use additives to further enhance your engines performance, purely on the basis that the oil companies do not use them – they do.

You must remember XADO is different as it is NOT an additive. The oil or grease is used as a carrier to deliver XADO to where it is needed.

No they are not the same and some of them can damage your engine. XADO is the original and all others are attempting to copy our process.

The reason why we are not on the high street is purely the fact that the major retailers do not always do justice to a popular product. We feel as though we can do better. We in fact regularly achieve the top position in most search engines so much of our sales are based online and we ship direct to individuals, dealers, motor factors and garages. Many of our customers order form us by way of a recommendation.

We are happy to deal with your order in any way you wish. If you are happier calling our office within office hours our sales staff will gladly process your order over the phone.

We are currently only offering engines oil purchased in a minimum of 1000 gal quantities for trade purposes. Our specialist field is in revitalization rather than lubricants as oil is a flammable liquid distribution in small quantities is a problem.  If you are looking to gain the benefits of revitlization for your vehicles, you are better off using one of our gel blister packs or 1 Stage revitalizants and adding this you your existing oil. If you are also looking to change your oil then use an oil available from any motor parts supplier and add our revitalazant to treat your vehicle.

We can quite understand your scepticism and we do not claim that XADO is a one stop fix all product. XADO has been independently tested and used by may customers in many countries around the world. All we can suggest is to try one of our products and see if it helps.

No. All our products have a Material Safety Certificate (MSC).  As XADO has been used to revitialize machinery in a food processing plant XADO also has a food hygien certificate.
