In the owners' defence, BMW themselves had changed their oil suppliers a few times throughout the e36 life..First valvoline, then Quaker State, then towards the end of life of e36 they signed the exclusive with Castrol.
In fact synthetic was not recommended for a while. in fact the grades listed in the owners manual, some of them don't exist anymore. So there are a lot of trial and error. If you are worried about your engine, always send a sample to Finning or BlackstoneLabs.

A lot of people love eating up the shit they read online so they start pouring fancy motor oils like German Castrol (0W30) into their cars only to realize it either burns too quickly (too thin) or some kind of Redline cocktail and it causes lifter tick.
