Sounds like a load of crap to me.

Unless they know you PERSONALLY they're going to simply assume you are just like the 99 other customers who doesn't know anything about cars. So they tailor their spiel to keep their jobs as simple as possible. Trying to explain to anyone that BMW engines require specific API and ILSAC ratings AND BMW's own LL-01 or better spec of a specific viscosity is useless. So they just tell you you can't use anything else or you shouldn't mix it because, well, to explain further would just be a waste of time, only confuse the customer more, and making more work in general for them.
SA is wrong period. I am not saying he can't simplify it; he just can't make blatantly wrong statements. You can't mix brands is simply wrong. All he had to say is that BMW recommends you use a certain type of oil. I would play it safe and just stick to BMW oil. Was that so hard? Did I lie or mislead?

If no codes are being thrown use Chevron Techron fuel injector cleaner (concentrate). It solves rpm fluctuating upon cold start-up. Also, for most BMW problems start off by scanning your car with the Peake Research Tool. It contains the actual BMW codes. If you want to register a newly installed battery for free (just buy a $10 cable) and google/download BMWLogger
