XADO EX 120 Car Engine Restore Treatment - Cylinder-Piston Group Repair - for Diesel and Gasoline Engines - Wear Protection Friction Modifier - Restores Compression and Reduces Noise (Tube, 9ml)

Does it work? I don't know because the application was impossible. When you read the directions it says to apply the product directly to the cylinder walls and to not get any on top of the piston. It goes on to say that the application can be done using a syringe. The problem with the method is that access is almost impossible through the method they recommend of removing the spark plug in accessing through the hole. You would need some kind of flexible tube that could be moldable yet rigid enough to make the angles needed. I ended up purchasing a set of craft syringes and trying multiple with no luck. I even used a borescope to verify. If you had Direct access to the cylinder walls say for example with the head removed off of an engine it may work but not practical for most applications.
