Geri,
As being someone that over researches before making a significant purchase, I have found that people tend to bitch alot. What I mean is...on these internet forums, people, myself included, are quick to post, blog, whatever about something that has gone wrong. As opposed to, "The [insert interest here] is working great...all is well here".
Of course this might not be news to you. Just an observation.
Just keep the oil flowing and the mix and timing in order and all should be well in the land.
