Compression check

I've checked the engine compression in my 17-year old Mazda 626 1.8 - it was very good! 200, 185, 200 and 200 psi. I guess it's true what they say about the good old Japanese cars.

I've checked it because I was worried about the white smoke coming from my exhaust. Now I think it might be due to the recent oil change. My Mazda is running on 10W40 now. The oil type recommended in the service manual is 5w30. I will soon change the oil again and see if it helps.

PS. Here is my "how-to" video made during the cylinder compression test https://www.youtube.com/watch?v=1xnoOHZfhco
