My mechanic did a compression test on my 95 LS with 125k on it. All cyl's were 150. This seems pretty low. My question is, is this bad?

 

If they are all pretty close, I doubt there's anything wrong. It's pretty rare for compression to drop too low but still stay consistent all across the board. Consistency across all cylinders is most important.

 

dyno the car. if the numbers are around what you expect, don't worry about it.

 

well if the car drives fine youre ok. i think ls's are supposed to be between 150-180...or maybe im making up stuff. but yea long as its consistent youre ok.

 

when i had my 1994 LS...it had 175k on it, and it read 190-200 across the board...id say ur numbers are pretty low...or maybe i was just gifted that perfect motor
