hi so a little while ago I did a compression test on my motor. I looked up the mazda fsm and also did some research on other sites as well as talked to multiple people who have rotary experiance and came up with the conclusion that if the motor produces 85psi or above three consecutive times in a row it is still a good motor. my test came out to be 90 to 95psi at 250rpm's on every jump. the factory service manual says 85psi. that being said do you think my compression is good? the car is a 93 with 62,xxx miles. thanks

With a normal piston compression tester? Yeah that's good for those miles
