There is no such thing. Every oil suitable for your vehicle will have at a min ACEA A3/B4/C3 ratings and by definition these will always be extended drain oils.
Like I said earlier:
"In the US that basically means:
-Castrol SLX OE Prof 5w-30 available at BMW dealerships and maybe Audi/VW.
-Mobil 1 ESP 5w-30 (Pepboys, Autozone, etc)
-Valvoline MST 5w-30/5w-40 (NAPA, and probably others).
- Motul & Total (Has a few LL-04 but they're usually mail order only)"
