If the end of compression pressure is lower than the standard, remove the test gauge connector and
add some cc of oil to the combustion chamber, make the engine turn (preferably manually) to lubricate
the cylinder.
Repeat the pressure test:
if the new values are low again, check the condition of the valve gaskets.
Pressure values too high in a new engine signal poor sealing of the rings.
