Mein Auto: 96 BMW Z3, 97 BMW M3
When the 1.9s were new they came with 15w-40 non synthetic oil. BMW was using Valvoline then. They later switched to Castrol 5-30 synthetic, I think in 1999. I have been using Royal Purple 15w-40 for the last 150k miles. I do live in Texas so I use it year around, you might want a thinner weight if you drive in the cold. But what you are reading is correct, although you will use 5 qts to get to the full line.
