I got 180 psi in all cylinders but this may have been because I put more oil in the cylinders than I probably should have....maybe 1/2 a shot glass worth? I'm not going to start the car until it's at least 10 Celcius here. I will let it warm up before I do another test. I'll bet it's going to smoke. Isn't 145 psi what it's supposed to read? Is my compression tester out of whack??
