If a factory value is not available you can estimate it by multiplying your intake . A tired engine will have 20% or more of cylinder leakage. I'd be more interested in those numbers, as a measure of engine efficiency. Just so you know, the volume of oil injected in the cylinders on the wet compression test effectively raised the compression ratio, by the volume of oil taking up space in the cylinder. When conducting a compression test, it’s important to interpret the results accurately. Consistent pressure readings across all cylinders indicate a well-functioning engine. However, if you notice significant variations in pressure levels, it could be an indication of underlying problems that require your attention.
Repeat test steps 3 - 5 on the remaining cylinders..
