The API , ISLAC or both upped the average cam and lifter wear allowance of the GM dyno mule engine from 20 μm maximum for the SL 30wts to 60 μm maximum for the SM-GF-4 30wts .
Wow! That is astounding. So it appears that engine wear is the sacrifical lamb to "mother earth." I bet the low zddp is the main culprit. Sort of like when the schools show better overall student performance by lowering the standards.
