There never was a question about the wisdom of changing oil at 10,000 miles.
I think everyone accepts that.
There never was a question about the spec of the long life 3 oil being the "best".
All I reported was that 2 VAG specialists who actually dismantle and rebuild engines,
and therefore see with mark 1 eyeball their condition,
have said that some of those that have used long life oil have been dirty and clogged,
those that haven't used it have been OK.
Now there could of course be lots of other reasons for each of these occurrences,
and we can all think of several,
and I don't believe that the cause-effect is in any way proven.
BUT, the first hand experiences of others who don't happen to frequent this site,
I thought, was at least worth knowing about.
It was my surprise at the initial comment from the first VAG specialist - see first post -
that prompted that post in the first place.
Sorry if all this challenges any deeply held beliefs.
