What is BMW Longlife-04?

BMW Longlife-04 is a motor oil specification developed for BMW petrol and diesel engines, particularly those equipped with advanced emission control solutions like diesel particulate filters (DPF). This low-SAPS oil ensures reduced ash buildup, protects engine components, and helps meet stringent Euro 5 and Euro 6 emission standards. It is suitable for long oil change intervals according to BMW’s service schedule.

Relevance: BMW Longlife-04 is a current and widely used specification for modern BMW vehicles. It has largely replaced older specifications, such as BMW Longlife-01 for models requiring low-SAPS oils and compatibility with advanced emission systems.

Main characteristics:

Viscosity: 5W-30, 0W-30, 5W-40, 0W-40, 5W-50
Specifications: ACEA A1/B1, ACEA A3/B3, ACEA A3/B4, ACEA C2, ACEA C3
Application: BMW petrol and diesel engines, including those a with DPF and advanced emission control systems

BMW Longlife-04 vs BMW Longlife-01: Key Differences

Features	BMW Longlife-04	BMW Longlife-01
Engine type	Petrol and diesel (with or without Diesel Particulate Filters)	Petrol and diesel (without DPF, older engines)
Emission standards	Meets Euro IV, Euro V, and Euro VI emission standards, compatible with vehicles equipped with a DPF	Meets Euro IV and Euro V emissions standards, designed for vehicles without a DPF
Protection level	Improved wear protection, especially for modern engines and DPF systems	Excellent protection for older engines
Oil viscosity grades	Typically 5W-30, 0W-30	Typically 5W-30, 5W-40
Compatibility	Designed for newer BMW engines, including those with advanced emission systems (DPF, SCR)	Designed for older BMW engines, both petrol and diesel (no DPF)
Fuel economy	Optimised for fuel efficiency, especially in modern engines and aftertreatment systems	Improves fuel economy for older engines but lacks specific features for modern emission systems
Extended oil change intervals	Supports longer oil change intervals for newer enginesi	Supports standard oil change intervals for older engines
Environmental considerations	Lower SAPS (Sulphated Ash, Phosphorus, and Sulphur) to protect the DPF and reduce emissions	Higher SAPS content, designed for engines that don’t have a DPF or modern emission reduction system
