01
What Longlife combines
A BMW specification brings together viscosity, performance and engine compatibility: wear, deposits, oxidation, cleanliness, service life, additives, emissions and aftertreatment requirements.

BMW Longlife
LL-01, LL-04, LL-12 FE, LL-17 FE+ and LL-22 FE++ should not be interpreted as a ranking where the newest specification is automatically better for every BMW.
Americopp rule
The correct Longlife specification for the engine, rather than simply the newest Longlife specification.
Selection must start with the vehicle, engine, year, market and applicable BMW documentation. Then check viscosity and specification.
Technical sequence
02
LL-01 and LL-01 FE
They are different designations. LL-01 is a longstanding specification used in multiple gasoline and selected diesel applications; permitted viscosities depend on the engine. LL-01 FE targets fuel economy and lower friction. BMW Peru lists 0W-30 for selected LL-01 FE applications; FE does not mean universal replacement.
03
LL-04
Low-SAPS formulation is particularly relevant to many diesel and aftertreatment applications, including diesel particulate filters. It also applies to selected gasoline engines. Compatibility depends on engine and market.
04
LL-12 FE
A fuel-economy specification for selected engines; BMW Peru lists 0W-30 for particular applications. It is not an automatic substitute for LL-01 or LL-04.
05
LL-17 FE+
A low-friction specification for selected engines; BMW lists 0W-20 in relevant applications. It targets efficiency and emissions performance and requires specific formulations. It is not a universal LL-01/LL-04 upgrade.
06
LL-22 FE++
A newer specification for selected applications, with efficiency and emissions objectives. BMW documentation may exclude it from certain engines. A newer designation is not proof of compatibility.
07
Selection sequence
Identify VIN, engine, year and market. Consult the applicable BMW specification, verify the permitted SAE grade and check the lubricant’s approval. Selection starts with the engine, rather than the bottle.
BMW Longlife is a specification, not just a viscosity
Longlife designations form part of BMW's technical requirements for lubricants intended for particular applications. A compatible SAE grade alone does not establish that an oil is suitable for a specific BMW engine.
Engine and generation
Application depends on the engine and its technical documentation. Do not extrapolate a specification from one engine family to another.
Market and emissions
Requirements may vary with the market, fuel and exhaust aftertreatment systems. A generic recommendation may therefore be insufficient.
Viscosity + Longlife
The permitted viscosity and BMW specification must be checked together. Neither replaces the other.
LL-01, LL-04, LL-12 FE, LL-17 FE+ and LL-22 FE++
These designations represent different generations and sets of BMW requirements. FE variants relate to efficiency and low-friction targets in applications designed for them. That does not make a later specification a universal replacement for an earlier one.
VIN / engine / year / market → BMW documentation → permitted viscosity + required Longlife specification
Common workshop mistake
Choosing oil because “it is BMW Longlife” or “it is the newest Longlife” leaves out the decisive question: is that specification permitted for this particular engine? The decision must be based on the vehicle's applicable documentation and the lubricant's actual declarations.
Approval and label wording
Distinguish an approval or specification declared by the vehicle manufacturer from marketing terms such as “recommended for” or “suitable for”. Before servicing, check BMW documentation and the lubricant's current technical data sheet.
Conclusion: Do not select BMW Longlife by number, date or viscosity in isolation. The correct reference is the specification permitted for the engine and the vehicle's application conditions.
