I won't pretend to speak for Larry.

I am not opposed to extended intervals. I am opposed to people recommending extended intervals without any testing, oil analysis or knowledge of folk's driving habits. That, in my opinion, is foolish and potentially very wasteful.

I am not a certified tribologist. I am a chemist employed in the petro-chemical industry and have been studying oil analysis on an almost daily basis for the past 4 years. I have also been maintaining my own cars for about 30 years. This is a hobby, I guess you could say.

I find it rather in poor taste for you to impune Larry Bible's integrity as you have. It is fine to disagree. But why stoop to insinuation?
