One of the cylinders showed only 60 psi on my first check,so i put oil in the cylinder to check for bad rings,it made the compression go up so i cranked the motor to get the oil out and also ran it for several minutes,but when i rechecked the compression it was still up to 160 psi.What does this mean?When i first checked the compression i did it three times and i was sure it was the correct reading. What could causae this.

make sure you unplug the injectors, so fuel doent wash down the cylinder walls, it sounds like you have a ring issue, if compression comes up when you add oil, it.
thanks. after i ran the motor and burned out the oil the compression was still higher than before .from 60 psi to 160
