So I have a 99 civic with a d16y8 auto. I decided to do a compression test because i felt i was lacking little power and my numbers were 125psi all across. The odometer only reads 153k miles so its making me question whether 125psi is ok for its amount of miles. My other civic with 300k miles had same numbers but I figured it was normal for its age but a motor with only 153k miles reading the same psi is worrying.

 

What is book about 150?
