Why does the compression in the engine’s cylinders increase?
Compression increases due to the restoration process within the piston block. More specifically, the fact that the piston block is cleansed of unwanted by-products and build-ups of engine fouling, as well as the formation of Practex’s protective nanolayer, the friction surfaces in the piston block are made smoother, thus giving rise to an increased compression figure. However it is worth keeping in mind that if you still get low compression readings, this might be due to mechanical damage in the engine, for example a blown engine valve.
