Jane and others,
I have a question about the use of MMO, which is very thin, right before an
emmisions test. At lower rpm's the engine vacuum is very high. Could you
be pulling the thinned engine oil past your rings or valve guides, causing
the higher hydrocarbons at idle?
Just a thought (guess). Personnally, I love MMO. It's great stuff. A
little dab of that almost pepper-minty stuff behind each ear drives the
women crazy. Whoops, I'll bet showering it off after the date is illegal
and constitutes a hazardous spill.
Just a though no one else has proposed yet. I have not scientific basis for
this possibility, just a gut feel.
Good luck,
Jack
