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.

spot on. good job.
