Overview of BMW Long Life oil specifications, covering application limits, viscosity grades, TBN, ash and Noack values for various engine models.
This document summarizes the BMW Long Life (LL) oil specifications, listing the applicable engine families, model years and regional restrictions for each LL code (LL‑01, LL‑04, LL‑12, LL‑14, LL‑17). It details which gasoline, diesel and M‑engines are permitted or prohibited, and notes mandatory use for engines equipped with DPF or GPF filters.
Technical parameters such as viscosity grades, ACEA classifications, Noack volatility, total base number (TBN), sulfated ash content and pour point limits are presented in tabular form for each specification, providing the minimum values required to meet BMW’s performance standards.
| Viscosity grade | 0/5W‑30/40 xW‑30 |
|---|---|
| Noack (ASTM D5800) | ACEA values (varies by spec) |
| Sulfated ash (ASTM D874) | ≥ 0.8 % m/m (up to 1.6 % for some specs) |
| Pour Point (ASTM D97) | max ‑42 °C |
LL‑12 specifies a viscosity grade of 0/5W‑30/40 xW‑30.
