According to my mechanic, whom I trust very much, your information is not correct. He is using the latest PET rev 194. I would like to sugar coat my response, but I belive him and he is seldom wrong and never when questioned and when he does his research. Are you suggesting PET is wrong?

PS: the rings appear to be cast Iron, which would be correct.

I may have confused myself. Mahle = nikisil. And: KS = alusil.

Sorry to say you may have the wrong rings in your car. My situation agrees with Dempsey.
