Like most other European car makers, Mercedes-Benz has long had their own motor oil specifications. While some European car owners may grumble about the fact that finding the correct motor oil for the car can be inconvenient (and possibly expensive). These motor oil standards do remove any doubt from the buying process.
Below is an explanation of each Mercedes motor oil standard along with the AMSOIL European Formula Synthetic Motor Oil that complies with the specification. We sell four different European engines oils formulated to meet the specifications for Mercedes-Benz cars and Sprinter diesel vans.
- AMSOIL SAE 0W-20 LS Synthetic European Motor Oil (MB 229.71)
- AMSOIL European LS 5W-30 Synthetic Motor Oil (MB 229.5, 229.51)
- AMSOIL European MS 5W-40 Synthetic Motor Oil (MB 229.51, 229.31)
- AMSOIL European FS 5W-40 Synthetic Motor Oil (MB 229.5, 229.3, 229.1)
- AMSOIL European FS 0W-40 Synthetic Motor Oil (MB 229.5, 229.3, 229.1)
This obsolete Mercedes motor oil specification was devised for both gasoline and diesel engines back in the late 1990’s. The MB 229.1 spec dictated minimum standards in terms of motor oil detergent levels and soot dispersant content. Motor oils suitable for the MB 229.1 specification required full-SAPS (Sulfated Ash, Phosphorus and Sulfur) levels. The AMSOIL motor oils that cover the MB 229.1 specification are AMSOIL European FS 5W-40 Synthetic Motor Oil and AMSOIL European FS 0W-40 Synthetic Motor Oil.
For gasoline and diesel engines covering model years from 1998 to 2004. MB 229.3 compliant motor oils also require high SAPS levels. MB 229.3 differs from the 229.1 spec in that it an MB 229.3 engine oil must also be capable of longer oil change intervals. They must reduce friction to improve fuel economy by a percentage point over 229.1. For cars requiring MB 229.3, use AMSOIL European FS 5W-40 Synthetic Motor Oil or AMSOIL European FS 0W-40 Synthetic Motor Oil.
This specification came into effect during the 2003 model year for both gasoline and diesel engines. MB 229.31 motor oils are required to have medium SAPS levels. This makes them compatible with Mercedes Bluetec diesel exhaust particle filters and the catalytic converters on the gasoline engines. Higher SAPS levels of some non-compliant motor oils can foul these emission components and cause operational problems. MB 229.31 motor oils must be designed for a service life of up to 15,000 km. AMSOIL European MS 5W-40 Synthetic Motor Oil is suitable for cars and Sprinter vans requiring the MB 229.31 engine oil standard.
For both gasoline and diesel engines, the MB 229.5 specification was released in mid-2002. This specification was designed to be an upgrade over the MB 229.3 spec in terms of fuel economy and oil change interval duration. MB 229.5 motor oils are formulated with high SAPS additive levels. AMSOIL European Formula “Full-SAPS” 5W-40 Synthetic Motor Oil and AMSOIL European FS 0W-40 Synthetic Motor Oil cover the Mercedes 229.5 engine oil standard.
Introduced in 2005, MB 229.51 was designed for longer oil life over the MB 229.31 specification. For gasoline and diesel engines. MB 229.51 oils must be capable of staying in service for 20,000 km. MB 229.51 oils must have low to moderate SAPS levels. This makes them compatible with catalysts in gasoline engines and diesel exhaust particle filters. Both the AMSOIL European LS 5W-30 Synthetic Motor Oil and the AMSOIL European MS 5W-40 Synthetic Motor Oil are designed for MB 229.51 service.
For 2019 and newer Mercedes-Benz models requiring a 0W-20 engine oil. This low-viscosity specification requires a low-SAPS formulation. MB 229.71 oils are compatible with gasoline, diesel and hybrid engines. AMSOIL SAE 0W-20 LS Synthetic European Engine Oil was introduced in 2020 was designed around the MB 229.71 standard.
