This is probably a very good description. My milano has been
running on full sythetic oil for many years. Last time while
changing the 2 piece headgasket off my 155k verde (remember the
longest lasking 2 piece headgasket story?) I found significant
gooey stuff in those wells. Can't imagine how much more goos
would be in there with conventional oil.
