Smile Advice on Compression test please?

Hi all enthusiasts, I'm about to buy a 2008 Mazda Demio, I have just had a full mechanical check done by a Mazda mechanic and the compression and TK head check came up okay.
Verbally I was told it was pretty good. The report says ok. overall condition was good. Just want to check with you experts Cylinder 1 160 ps, 2 163, 3 163, 4 168
Would love see feedback thanks :-)

Your reported numbers are good nothing to worry about if they did the test correctly.
A cylinder compression TEST KIT are very inexpensive and very easy to use. If you can change spark plugs you can do a compression test! I usually do at least 2 complete test runs @ 5 cycle max counting on the compression stroke to match and verify the results of the first test.

Your welcome and

WELCOME TO THE FORUM
If you do decide to do your own compression test there are a couple of us that can instruct the correct way to do it. But as I said your engine numbers look good!

Thanks really appreciate that :-).
I'm happy to buy the car now, the test was done by a good Mazda mechanic and not who I'm buying from and your opinion is valued as a second opinion. This kit sounds useful will look into it for future reference. cheers
