180 across is good, thats the same reading i had on a 92 civic lx with 260km

170, it just weaker , but keep an eye on it if it goes lower

what year is your car and how many Km is it?

Do you race sometimes? I like to race ppl so I know how that car is supposed to be like, espeically if they have the same car as mine. Sometimes the numbers don't really tell what the car is like

Don't worry.

Don't worry. Those numbers indicate a strong motor.

Research has shown often times one cylinder is lower than the others.

Also, the seal that many compression testers make isn't 100% perfect. Perhaps the lower cylinder had a bit of anti-sieze or some crap that got on the tester seal. Keep it clean when testing.

Try it again another day, and try that (lower) cylinder first.

Perform a wet and dry test on all cylinders... generally it's nothing to worry about till it's down to 135, then it's really time for a rebuild LOL As long as it runs, it runs.
