You mean it seeps past the rings when the car is off, collects, and then burns at once on restart? You don't think enough oil might get passed the rings once the car is really hot that it could affect the catalyst efficiency?

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
