I'm experiencing this first-hand on a car that has no leaks, but consumes a little oil. This was true even with multiple OCI's of PUP and M1HM. However, with PPHM, consumption continues to decrease. (All mentioned are 5w30's.)
So, it's unusual that PPHM is thinner than its regular PP counterpart.
Is it likely that the PPHM version using better base than the regular PP??
