this board has threads on this, Timsco initiated one, for example. I am interested in this topic becuase of one of the conclusions that we seemed to reach - the oil consuption / smoking av issue (on start-up, it seems) has been largely associated with early build date avs (I have one of those), pre- 11/01 builds if I recal the general conclusion. this led to a flurry of questions about how to determine one's build date, to head off that topic again the build date is noted on the driver side door placard.
Mine is not smoking yet or showing an appetite for oil, but keeping an eye on it!
