G'day. I have a 2007 Suzuki Swift.

It has done approximately 260,000 KM's so far.

I have compression tested all cylinders and they all 100 psi.

Some people are telling me Thy should be at least around 150 psi.

Should I be worried?

I am the second owner of this car since 240,000 KM's and have done oil and filter changes every 10,000 kms.
