Mazda2 cylinder compression number

[envy2]

I was wondering if anyone has the expected numbers for a compression test on the mazda2. I'm planing on doing one over the weekend but does not know the numbers. Thanks.

220 normal 154 minimum

Why is there such a huge difference between 220 and 154. I got 175, 173, 172, 180 from left to right. Btw it was a cold motor because by the time I got everything off and went and buy a spark plug socket the engine has cooled down already.

Your not below 150 and they're close in range to each other. Should be good.

whats the compression ratio of the 1.5 mz2?

It is 10.0:1 per mazda website.

Warm up your engine to normal working temperature and measure again just after you turn it off.
