I have heard some bad stuff about the Prothe and Grant rings, so good job to you sir getting the first 30,000 out with no issues.
I just know that once I got the oil leaks sorted I never had to add oil. I added about 1/2 a quart from the first start to when I discovered my oil leak. After the oil leak and running syth oils I never had to add one drop of oil and that was with 7,000 mile oil changes. MY POINT: the Goetze rings did not let my engine burn a drop of oil and I want to know if the KS will do the same.
The other kicker is I have both Goetze and the KS rings in the .020" over, but I don't know what to do.
